- the processing head either be arranged to remove material from the work piece or may be otherwise arranged to process the work piece by addition or deposition of material or may be arranged to inspect or monitor the work piece. Such heads may be loosely referred to as processing heads. In some cases it will be appreciated that the processing head may be arranged to process the work pieces by heat treatment and may remove some of the material of the work piece in the processing. Other processing heads are arranged to remove material from the work piece.
- each tool changer has a number of processing heads stored therein.
- the first tool changer preferably stores processing heads designed to remove material from a work piece.
- Such heads may be arranged to carry out milling, grinding, planning, boring, ablation, machining and other material removal processes as are well known in the art.
- the machining may be laser assisted and the processing head may utilise coaxial laser delivery or off-axis laser delivery.

- heads may be any one or more of the following: an image recording apparatus; lighting, either fixed or moving; touch probes; 3D surface
- each tool changer is adapted to store from 5 to 50 heads, or more preferably from 10 to 40 heads or most preferably from 25 to 35 heads. It will be appreciated however that as in common practice a tool changer can be expanded to store more heads if required.
- the respective tool changers store the processing heads remote from the work piece.
- Such storage of the heads in a remote location from the work piece allows a larger number of heads to be stored and to be available for selection as well as prevents them from becoming contaminated from the work piece. Additionally as only the “in use” head is attached there is a greater range of movement available to the head relative to the work piece.
- the first carriage is parked while the second carriage is in use and vice versa.
- the machine comprises a body having a clean side and a dirty side.
- Each side may comprise a chamber that may be sealable.
- at least the clean side comprises a sealable chamber.
- the clean side may comprise a chamber, such as a tool changer, in which clean heads are stored.
- the dirty side may comprise a chamber such as a tool changer, in which “dirty” heads are stored. Such “dirty” heads may be used for removal of material from a work piece.
- the first and second tool changers are preferably remote from the work station.
- the machine is arranged to control an environment of the work station
- the work station is located between the clean side and the dirty side.

- the inert gas may also be provided as a coolant.
- the carriage may provide a means of supplying fluid to the chamber or to the work piece.
- the fluid may be a gas.
- the gas may be inert and/or may be acting as a coolant. In some cases the gas may assist in extraction of waste material. In other cases an inert atmosphere may be provided and a coolant gas may be supplied to the work piece in addition. Where the work piece is submerged in an inert gas, any waste material or coolant extraction preferably rises above the level of the inert gas so that upon extracting coolant and waste material, the inert gas is not expelled from the chamber.
- a waste extraction means may be provided. In a preferred embodiment an extraction point is provided which is connected to a duct in the machine.
- waste is removed by means of an Archimedes screw operating in the duct.
- This arrangement preferably extracts the coolant straight up the centre of the screw and out of the chamber, yet always leave a column of inert gas and fluid in the duct, which would provide a natural airtight barrier between the chamber and the atmosphere.
- the chamber may be at least partially sealable. It is desirable in managing heat in the work piece that the work station is liquid cooled. Typically the work piece will be held in a work holding device on a platform in the work station. The platform or at least the work holding device may be cooled with a cooling liquid or gas such that heat generated by material deposition on the work piece is removed through conduction to the work holding device and into the cooling system. Advantages have been found in that the cooling enable higher work cycles to be maintained for deposition. Additionally the machine is insulated from the heat of the work piece which helps axes of the machine to maintain the accuracy that they are designed to hold and prevent damage due to thermal expansion of moving parts.
- the chamber may be sealable and a vacuum may be applied to the sealed chamber such that material processing is carried out in a vacuum or under a pressure reduced from atmospheric. Alternatively it may be desirable to increase the pressure in the chamber above atmospheric pressure.
- the chamber may be unitary on at least two, three, four or five sides.
- a lid or other sealing mechanism may be provided to seal the chamber.
- a sealing door may be provided.
- Preferably means for introducing a gas or applying a vacuum is provided in at least one face of the chamber or door.
- the chamber may be partially open and may be provided with a local shielding.
- a local shielding may be expelled openly, or preferably may be confined by using a bag, such as a plastic bag, or a skirt that can be located around the work piece during processing.
- the skirt could be supported on a plunger and the locating of the skirt around the work piece may be automated.
- first and second devices are moveable in at least x, y and z axes. In a preferred embodiment the devices are slideable in at least one of the x, y and z axes.
- one of the slideable axes is in the x directions and a rail is provided which is common to the first and second devices.
- the first and second carriages are each mounted on respective first and second supports.
- the first and second supports are preferably each slideable in the rail so providing movement to the first and second carriages in the x direction.
- each carriage is moveable in the z direction relative to the support. Desirably the movement of the first and second carriages on the first and second supports in the y direction is parallel.
- the machine may be provided with further variation by control of orientation of a platform supporting the work piece.
- the platform may be fixed providing flat table or may be rotary or may in some cases be arranged to tilt as well as rotate.
- the platform and the chamber are advantageously arranged to accommodate a work piece having a size as known in the art of machine tools.
- the machine is cuboid and overall size the footprint of the machine is from 1 m to 5 m or more preferably from 2 m to 4 m or most preferably about 3 m.
- the machine is preferably optimized for high speed machining of light passes since the amount of heavy cutting, traditionally known as “roughing” would be reduced due to the addition of material which is near-net of the target shape and therefore a work piece will require mostly “finish machining”.
- the machine provides an integrated docking system.
- the integrated docking system may deliver material and energy to a processing head on the first or second carriage which may be arranged to remove material from the work piece or may be arranged to process the work piece.
- the docking system is arranged to provide a clean connection between a processing head and the docking manifold on the machine.
- An operable seal may be provided on both halves of the mating manifold.
- portions of the head which are sensitive to contamination, such as the optical windows for laser energy may be covered by a sliding or rotating door which is only opened after the head manifold and dock manifold mate, thereby eliminating the opportunity for contaminants to accumulate on said sensitive areas when the head or dock are in a storage position.
- positioning of an air knife may be used to blow off any contaminants after the doors are closed to ensure the powder ports and other docking manifold connections may be kept clean.
- Material delivered to the processing head may be in the form of powder, fluid, or filaments.
- the material may comprise a polymer material.
- the material may be selected from a group comprising metals, non-metals, polymers, ceramics, clay, salts, conductive, capacitive or dielectric materials, in powder form, filaments, rods, fibers (short, chopped, long, or continuous) sheets, or wires, in solid or semi- to fully liquid form.
- materials can be provided in suspension in a liquid, emulsion, gas, aerosol or paste.
- continuous or discontinuous fibres may also be deposited to form a composite material.
- the media may comprise a polymer pellets or filament.
- such a feedstock may be heated by an energy source to a temperature such that the material can be fed, directed, extruded, jetted or otherwise deposited in a controllable manner.
- a fluid material may be supplied to the processing head from a media reservoir which may be provided in the machine. The material may be heated by an energy source till all the material in the reservoir is fluid and can be extruded in a controllable manner.
- the material may also comprise conductive, semi-conductive, capacitive, piezoelectric and dielectric material such that electric circuits can be laid down during formation of the work piece.
- the media may comprise metals which may be provided in the form of powders or wires. Such metals may be used in forming the body of the work piece or may be applied to a part of the work piece in order to lay down electronic circuits.
- a particular advantage of the machine is that a wide variety of heads may be provided and these are able to deposit material so as to produce work pieces complete with embedded electronic, biological and other functional subsystems.
- machine may be used for making prototypes, end use products and entire products.
- the integrated docking system is arranged to be able to supply material and energy to the processing head when required.
- the laser energy required for processing is delivered parallel to the z axis, but from a point removed from the close proximity to the working area. It will be appreciated that advantages arise as the laser beam path can be direct and so the laser power that can be delivered is reduced less because of the few reflectors and optics than with side docking delivery of laser power which necessitates the use of mirrors in the beam path.
- the docking may be provided on a top face of the processing head and the integral docking in the carriage is arranged to align and to mate with a manifold on the carriage with the processing head.
- a manifold and docking means may be provided in a collar of the carriage.
- the carriage may comprise a spindle arranged to be moveable in the z direction and the docking manifold may be provided on a collar of the spindle.
- Provision of an integral energy source in the machine has a number of advantages.
- the energy source may be by means of a beam targeted on the work piece.
- Control means can be provided to control the applied beam of energy and the source may be selected from lasers, such as infra-red lasers, visible light lasers and UV lasers. Pulse durations may be controlled to vary from an attosecond (as) up to femtosecond (fm) and so on up to continuous wave (CW) durations.
- the energy source selected may be chosen depending on the process being carried out—whether removal, addition or alteration of the material.
- the energy source and pulse duration may also be selected to optimise absorbance of the energy by the material to be processed.
- a beam switch may also be used for changing between different laser beams sources.
- the energy source may be supplied to the work piece or to the processing head, particularly a processing head, using a fibre optic cable arranged to be carried by the carriage to the processing head. It will be appreciated that in some cases a hollow core may be required due to the energy density.
- the machine has a clean side and a dirty side and the work piece can be located in a chamber.
- the processing heads or deposition heads are maintained in a clean condition. It will be understood that contamination of the work piece in the course of deposition or processing of the work piece can lead to poor quality finishes or imperfections in the material. Accordingly it is important to maintain the processing heads used on the clean side without contamination or to minimise contamination that can occur.
- the machine and particularly the processing heads are cooled using a cryogenic cooling system.
- a cryogenic cooling system Preferably an organic coolant is used which evaporates, vaporizes, flatulises or otherwise combusts to form products with a very low ash content and which leave no residue behind.
- other coolants may be used such as liquid nitrogen.
- the coolant may be supplied to the chamber or the coolant may be supplied to the work piece or to the processing head.
- the clean side can be maintained by providing seals between the chamber and the clean tool changer.
- Any processing heads used for deposition or processing may be stored in the second tool changer and the second tool chamber may be suitably sealed. Processing heads used for milling do not need to be kept in a clean environment and are stored in the first tool changer when not in use. As the first tool changer is on the “dirty” side the first tool changer does not need to be sealed from the chamber or the work piece.
- the machine is provided with duplicated supports and carriages arranged to move in the z direction.
- the supports and carriages are the same.
- one of the supports and carriages is used exclusively for clean processing and the other support and carriage is used exclusively for “dirty” processes.
- docking of the heads on the carriage and support is arranged to maintain a clean environment.
- the optics of laser processing heads are not exposed to the air and are maintained in a clean environment at all times.
- an automated cover system is provided whereby actuation of a cover on the dock opens a corresponding door on a selected processing head. Once docking of the head on the carriage has been completed the system is sealed. Automation of the docking process allows the process to occur with out visual inspection being required. It will be appreciated therefore that a machine equipped with an automated docking and not requiring visual inspection may use higher power lasers since it is no longer necessary to provide laser safe windows for inspection.
- the environment may be maintained as a clean environment by the use of air knives and air purging. This may be particularly desirable around the areas used for head changing and for docking of the head with the carriage.
- the second processing heads are maintained in a clean environment during storage in the second tool changer.
- a separate storage area is provided for processing heads.
- the processing heads may be reversed into the tool changer such that a face of the processing head is sealed against a surface of the tool changer pocket.
- the machine comprises a waste extractor. This may be used to remove swarf from the bottom of the working area where it accumulates with the cutting fluid. Additionally, fumes and humidity may be removed from the working area using appropriate filtration, extraction and dehumidification. Such an air filtration/de-humidifying system prevents airborne contaminants and humidity from affecting the cleanliness of the working area.
- a tray may be provided in the machine that can be slid into the chamber to capture overspray powder.
- material captured by the tray can be collected and may be re-used directly or may be reconditioned and re-used. Some material may escape the powder collection tray.
- Such material is typically removed from the chamber with the coolant and may be filtered from the coolant and re-used.
- An important aspect of the machine is the provision of integral monitoring of the work piece and the processing head or heads.
- At least one of the following monitoring methods may be provided on the machine.
- the melt pool in processing or additive manufacture may be monitored.
- a thermal history of the work piece may be monitored and recorded using thermal cameras.
- Oxygen sensors may be provided in the chamber.

- wireless communication is enabled between the processing heads and a controller in the machine. Communication with a remote controller or output may also be provided. Such communication may use IR or radio data transfer. Additionally communication of processing data using MT Connect may be utilized or other established wireless protocols.
- a focal length of any optical elements may be monitored and data output.
- sensors and circuitry may be embedded into a work piece as it is being made to form a monitoring device that can monitor the condition and health of a part in use.
- such sensors and monitoring devices to be printed into and onto work pieces may be arranged to function and give feedback to users prior to completion of said part. It is envisaged that the monitoring devices could continue to function throughout the service life of the part.
- An example of such a monitoring device would be a strain monitoring circuit, which could detect when a device had been loaded beyond a safe condition.
- data from the machine and from processing heads may be output to remote monitoring means.
- a performance of the machine and the delivery heads and data from the chamber and the work piece is monitored and reported in real time.
- an analysis may be carried out in real time.
- a statistical analysis may be carried out to predict failure of work pieces.
- the analysis may be applied to the processing heads to identify potential failure of the processing heads. In all cases it is preferable for the detections to form a closed loop feedback system to ensure quality production of parts and if needed enable remedial re-work of areas of the parts that do not meet acceptable quality standards in situ to avoid scrapping the part.
- the docking system is arranged such that docking between the carriage and the head is at a top face of the processing head.
- integral docking with the carriage aligns and mates a manifold on the carriage with a cooperating manifold in the processing head.
- the manifold is orientated perpendicular to the delivery head loading axis. This may eliminate or reduce the need for the supply docking manifold to be moved since the processing head docking action also accomplished docking of the manifolds. It has been found that this action is particularly suitable for energy sources that do not require a line of sight but it can also be used with lasers and with other energy sources.
- connection between the carriage and the processing head is arranged to be sealable so as to preferably exclude contaminants.
- the processing head manifold is arranged to be fixed. However in some preferred embodiments the manifold is arranged to move outwardly from the processing head to a docking position. This has been found to be particularly advantageous as the processing head occupies less space in the tool changer.
- a seal can be provided over the manifold. This is particularly advantageous for processing heads that are used on the clean side and for which it is desirable to maintain all of the elements in as clean a state as possible. Such a seal may be provided by a sliding door.

- the deposition of the material for the article may occur in an iterative manner: ie some material is deposited, processing heads changed; other processing performed; deposition head returned and further material deposited and such a process flow is described in relation to FIG. 19 .
- the controller 306 then causes the machine tool to select a second processing head (step 606 ), which in this example is processing head 310 .
- a second processing head which in this example is processing head 310 .
- the area onto which the laser beam is focused from the processing head 310 is smaller than the area for the processing head 312 .

- process step 602 may have been used to deposit layers 700 and process step 604 may have been used to deposit layers 702 .
- FIG. 16 shows only a single change of processing heads, other embodiments may provide multiple processing head changes in order to work on the work-piece. Each sequential processing head selected can be controlled by the controller using information from an inspection or analysing head and depending on the work piece to be created.
- the head 310 has been used to fill in the stepped nature of the surface part 704 (ie the work-piece) being fabricated.
- the surface of the part becomes a closer approximation to the desired surface 706 and the second processing head used in step 606 has been used to improve the fidelity of the article being created to the desired article thereby removing, or at least reducing, the need for surface finishing of the article.
- a higher fidelity to the intended surface may be achieved as shown in FIGS. 17 b and 17 c.
- FIG. 17 b illustrates an embodiment where the second processing head allows material 710 a - e to be deposited with sufficient resolution that the final, desired surface 706 can be substantially achieved without the need for further processing.
- FIG. 17 c shows an embodiment in which a liquid has been deposited by the second processing head, and due to the surface tension within that liquid (prior to solidification), the deposited and solidified material 712 a - e forms convex surfaces extending slightly beyond the desired 706 final surface.
- the surface may have an acceptable surface finish. If this is not the case then further processing and/or machining heads may be used to further work the work-piece. For example smaller amounts of material could be deposited within the remaining steps (eg 708 ) between the layers 700 and 702 to make the surface a closer approximation to the desired surface 706 .
- a milling head may be selected to remove material to provide the desired surface. It will be appreciated that in such embodiments less material will need to be removed when compared to embodiments in which the material layers 702 a - c was not deposited by processing head 310 . Thus, it will be appreciated that embodiments providing the method as outlined in relation to FIG. 17 provide a surface finish that is either i) acceptable without any material removal; or 2) requires much less material removal to provide the finished surface when compared to an embodiment in which layers 702 a - c had not been deposited. In the example, of FIG. 17 the material being deposited in layers 700 and 702 is largely the same but with the rate/amount of material deposition being varied between layers 700 and 702 .
- FIG. 18 is used to exemplify another example of FIG. 16 in which the material is varied between steps 602 and 606 . It will be appreciated that it would also be possible to vary the rate/amount of material being deposited in addition to varying the composition of said material.

- step 606 the second processing head is used to deposit a material having a different property in the layers 800 a - d when compared to the layers 700 a - d .
- the skilled person will appreciate that whilst the layers 800 a - d are shown, in this embodiment, as being on the faces of the layers 700 a - d this need not be the case.
- the different property is provided by a different micro-structure of material.
- the material deposited in layers 800 a - d has a different heat treatment, whilst it could be substantially the same material as that in layers 700 a - d , and therefore has a different hardness.
- the layers 800 a - d may constitute a hardened bearing surface, cylinder sleeve of the like.
- step 602 may be used to deposit a metal and step 606 may be used to deposit a plastic.
- the layers 800 a - d may not be provided by further material and may simply be provided by a heat treatment to the surface region of layers 700 a - d .
- Such surface region treatment may be provided by a heat source, such as a laser, or the like. An alternative treatment will be described in more detail below.
- FIG. 18 is used to exemplify embodiments in which step 606 is used to deposit materials of different properties (whether bulk or nano/micro-structure) when compared to the material deposited in step 602 .
- FIGS. 19 a -19 b are used to exemplify a further example of the process outlined in relation to FIG. 16 .
- a first processing head is used to deposit a series of substantially annular layers 900 a - d .
- Each of the layers are shown and thus the interface between each of the layers is visible in the figure.
- this interface between layers 900 a - d will be present both on the outside of the annulus of each layer and also on the inside of each layer.
- the second processing head used in step 606 is a material removal head, such as a milling machine, or the like.
- the material removal is not only used to smooth the outside surface of the layers, as shown at 902 but also to smooth the inside of the annulus in a similar manner.
- further material may be deposited using a second processing head in order to improve the fidelity of the inside surface of the article being created to the desired article in a similar manner to that described in relation to the outer surface in FIG. 17 .
- the number of layers deposited using the first processing head in step 602 is limited to the extent that the second processing head used in step 606 can reach sufficiently far inside the work-piece 902 .
- step 606 it can be seen that once the second processing head has been finished with in step 606 , the first processing head is again used a further four layers 904 a - d are deposited on top of the work-piece 902 . Then the second processing head is again used in step 606 and both the internal and external surfaces of the new layers 904 a - d are processed to generate work-piece 906 .
- Embodiments, in which the internal surfaces are smoothed in this manner may find utility applications in which a gas, a liquid, or other fluid or fluidized material flows through work-piece 906 since it will be appreciated that smooth internal surface can lead to a better fluid flow.
- Examples where such a structure may be useful include fuel lines, hydraulic lines, cooling channels, flow tubes or the like.
- FIG. 20 is used to explain a further example of how the process of FIG. 16 might be utilised.
- a first material is deposited.
- the material is deposited as half a cylinder 1000 in a first material.
- This cylinder 1000 will be a sacrificial material as described hereinafter.
- a further material 1002 is deposited over the sacrificial material 1000 .
- the sacrificial material 1000 supports the arch 1004 so that the arch 1004 can be fabricated and thereby, the sacrificial material 1000 provides support for material deposited in latter processing steps.
- the sacrificial material 1000 can be removed. The skilled person will appreciate that further processing steps may be completed before the sacrificial material 1000 is removed.
- the portion of material 1002 may any suitable material for acting as a support.
- the portion of material 1002 which may be thought of a support material, may typically be a soluble polymer material or a loosely bonded/confined particulates or powder. It may be in a solid part filling the void or may be created as hollow self-supporting structure according to the limitations known in the art of directed energy deposition.
- a support structure could be made in a form that resembles cathedral like arches. It could also be made in such a way that it is easily removable by machining.
- FIG. 21 provides a further example in which a support, or sacrificial, material is deposited to facilitate fabrication or repair of the underlying article.
- the article being fabricated is a turbine blade 1100 .
- some embodiments are arranged to encase this fir tree root portion 1102 within a block of sacrificial material 1104 (shown here in dotted outline).
- This sacrificial material 1104 could then be clamped in order to hold the turbine blade 1100 during subsequent steps.
- the sacrificial material 1104 provides a temporary, sacrificial, material which aid physical location of the work piece.
- one embodiment provides a further portion of sacrificial material 1106 toward the end region opposite the fir tree root portion 1102 .
- This further portion 1106 allows the blade 1100 to be held at two points at the regions of sacrificial material 1104 , 1106 and the blade 1100 is protected from damage by the clamping means (such as a vice, or the like).
- a processing head may be used to provide a protective material arranged to protect a surface region of the work-piece.
- the protective material may (or may not) be a sacrificial material which is removed later in the fabrication of the article.
- a processing head may be used to inspect an article.
- the processing head may comprise any one or more of the following: image recording apparatus; lighting; touch probes; 3D surface and volumetric scanners; photogrammetry systems, sensors (such as oxygen sensors; thermal sensors; thermal cameras); eddy current generators; ultrasound transducers (for air, gel, and liquid coupled); electromagnetic wave generators or the like.
- Inspection data can be transferred from the processing head to the controller and from the controller to the processing head to control the inspection.
- Some embodiments may flush a processing head. Such embodiments are advantageous because they help to ensure that the processing head is clean for its next use and help to avoid contamination of materials. Further, such embodiments help prevent wear to components through particles of material left within and/or on a processing head.
- a processing head is returned to the tool changer 308 is flushed with compressed air.
- other gases eg an inert gas such as nitrogen or the like might be used.
- Other embodiments may have fewer or more material feeds used one at a time or in combination to provide in-process alloying.
- four feeds can be used to provide flexibility in how material is delivered from the supply-unit 414 to the processing head 400 and can be used to improve the speed with which a material change can be made and also to reduce the chances of contamination.
- material of a first kind may be fed to the processing head 400 using two feeds. Then, it is desired to switch materials and so flow of material is stopped, or at least diverted, using a by-pass circuit, away from the processing-head 400 .
- a by-pass circuit a by-pass circuit
- the processing head is flushed with air and subsequently the two feeds not previously used are now used to supply a second material to the processing head.
- Such an embodiment is advantageous as it allows the supplied material to be switched from the first material to the second material quickly without the need to change processing heads 400 or change supply-units 414 whilst ensuring that no contamination of the materials occurs.
- Various actions may be performed to assist changing from a first processing head to a second processing head.
- parameters associated with the processing head to be used are loaded for use into the controller 306 .
- the controller 306 parameters associated with the processing head to be used are loaded for use into the controller 306 .
- a wide variety of processing parameters are stored for each deposition head including powers, feed speeds, gas flows, etc. and rates of change for each of these triggered by geometry requirements. These settings may be stored in database tables in a separate controller and called up as needed or they may be fully integrated into the machine tool controller and called using custom M-codes or other suitable signals.
- parameters for deposition heads may be used with functionality in the controller already associated with conventional cutting tools such as offsets.
- Embodiments may re-purpose the parameters stored in relation machining heads (eg a milling head or the like) to allow those parameters to be used with non-machining processing heads (such as deposition heads, probe heads and the like). For example, at least one of the following parameters may be stored for a processing head:
- the tool length stored may be modified or compensated such that the processing head length is increased beyond its physical length to include the designed stand-off distance of the processing head from the build surface (ie the surface of the work-piece 304 ).
- the stand-off distance is the required distance between the processing head and the work-piece 304 and may be adjusted to manipulate the deposition width.
- the controller 306 is arranged to vary the stand-off distance, and therefore to vary the stored length of the processing head, in order to vary the distribution of the laser beam power that is imparted on to the work-piece 304 .
- the controller 306 is arranged to vary the stand-off distance, and therefore to vary the stored length of the processing head, in order to vary the distribution of the laser beam power that is imparted on to the work-piece 304 .
- the skilled person will appreciate that as the laser is moved toward or away from the work-piece then it will move into or out of the nominally engineered focus. Accordingly, using a processing head length which includes the stand-off distance can allow the focusing of any energy source provided by the processing head, which in the embodiment being described is the laser.
- Some embodiments may measure the amount of back reflection of the laser from the surface of the work-piece 304 and aim to minimise this amount; as such, the processing head is arranged to measure energy returned from the work-piece from energy directed (ie the laser), from the processing head, toward the work-piece. It will be appreciated that once a laser is focused then maximum power will be coupled into the work-piece 304 and that therefore, the amount of laser light reflected from the surface will be a minimum.
- This process of determining the ideal focus may be a stored routine which moves the head through a range of stand-off distances to establish the ideal focus and then the optimised outcome of the process can be stored in the CNC tool length tables as described above, or otherwise.
- any processing head where the deposition or processing point is not on the spindle centerline can be stored as a fixture offset and called when the head is loaded into the spindle, thus re-purposing another standard CNC feature to accommodate the use of multiple heads.
- embodiments may store further parameters for a processing head. For example, parameters may be stored that determine the flow rate of any media 424 , flow rate of any shielding gas, or the like; determine the power of any energy source (such as laser 416 ).
- the parameters mentioned in this paragraph may indicate how they should be varied according to motion of the processing head. For instance, it will be appreciated that as a processing head approaches a turn within its path then it is likely to need to slow down in order to achieve that turn. Accordingly, as the processing head slows it becomes advantageous for embodiments to reduce the flow of media 424 ; reduce the flow of shielding gas; and reduce the power of any energy source (eg laser 416 ).
- Some embodiments may use a processing head 1200 which use mechanical means, such as a syringe 1202 or one or more Archimedes screws (not shown), to eject or extrude material 1204 from the head 1200 .
- mechanical means such as a syringe 1202 or one or more Archimedes screws (not shown), to eject or extrude material 1204 from the head 1200 .
- Such embodiments may work with a material feed from the supply-unit 414 or may additional supply media from a reservoir within the processing head 1206 .
- Some embodiments may use the spindle rotation (of the machine tool) to directly control the amount of material extruded.
- the plunger or other means for causing displacement in the syringe 1202 is coupled to the spindle with the tool holder and thereby commands to control the spindle motion changes the displacement which controls the deposition rate.
- there are one or two Archimedes screws which are arranged to interact to plasticise a material (typically by shearing the material after the manner known in injection moulding), typically a polymer, within the processing head.
- the energy to rotate the screws may come directly from the spindle rotation.
- a heater can additionally be provided in order assist plasticising of the material. The heater may be powered by electricity generated from the spindle motion.
- the processing head is arranged to sense the spindle speed of the machine tool to which it is attached and to use that spindle speed to control the mechanical means within the head. For example a transition from a first speed of rotation to a second speed of rotation may indicate that flow should start. A transition from a high speed to a low speed may indicate that flow should cease.
- FIG. 23 illustrates a further embodiment in which a processing head 1300 is positioned above an article that is being inspected 1302 .
- This article may still be in the process of being manufactured and an inspection step may be performed as part of the process described in relation to any of the Figures above.
- the article 1302 could also be a finished article to be inspected.
- FIG. 23 shows a fluid 1304 being ejected from the processing head 1300 and impacting upon a surface of the article 1302 .
- the fluid is a cooling fluid typically used by the machine tool in which the processing head is mounted to cool an article being milled, drilled, or similarly processed.
- the fluid sprays away 1306 from the surface 1302 .
- a channel 1308 is provided along a central region of the processing head 1300 . The channel is arranged to ensure that the fluid 1304 , as far as possible, has a laminar flow since turbulence within the fluid flow can reduce the coupling to the article 1302 .
- the fluid 1304 is through spindle coolant.
- the fluid 1304 provides sufficient coupling for an ultrasound transducer 1310 provided within the channel 1308 and in communication with the fluid 1304 flowing therein for ultrasound transmitted by the transducer 1310 to be couple to the article 1302 .
- embodiments as described in relation to FIG. 23 can be used to inspect articles 1302 using ultrasound.
- the skilled person will appreciate that such inspection may be useful in determining the presence of voids and the like within the article 1302 .
- the fluid may be deposited onto the surface and latterly used by a processing head to couple that processing head to the part to make an inspection, such as an ultrasonic inspection, using that fluid as a coupling medium.
- a processing head to couple that processing head to the part to make an inspection, such as an ultrasonic inspection, using that fluid as a coupling medium.
- the processing head making the inspection may be the same or different to the processing head that deposits the fluid.
- the fluid may be a gel or the like.
- the gel may be termed a sacrificial material as it does not end up in the final article and used as part of the inspection process.
- FIG. 27 An alternative processing head 1700 is shown in FIG. 27 having a 1702 in the form of a chisel.
- a surface of the work piece can be treated with the chisel tip to reduce stress in the work piece or a part of the work piece.
- the chisel tip may be kept stationary or may be moved by movement of the spindle. Alternatively they can be actuated by mechanical or ultrasonic means which can be provided within the processing head.
- the processing head 1800 has a tip in the form of a pin 1802 .
- the pin can be used to relieve stress and strain, particularly tensile stress, in the work piece.
- Alternative configurations of the tip of a processing head are shown in FIGS. 29 a to 29 d .
- the tip may have one, two, three or more pins. Arrays of pins can be used as can be seen in FIGS. 29 c and 29 d .
- the controller can choose a head with a particular arrangement of pins to apply pressure to the required part of the work piece and the arrangement selected is suited to the geometry of the work piece.
- the selection of heads can be pre-determined using planning software ahead of time such as with CAM software.
- the pins have a circular cross section but the skilled person will appreciated that the pins may alternatively have rectangular, hexagonal, square or other cross sections. Such cross sections may be used if an array is required in which there are not gaps or overlaps.
- the processing head is actuated to impact upon or apply pressure to the work piece. This process is referred to as peening.
- the application of pressure relieves tensile stresses and applies compressive stresses to the work pieces so improving the characteristics of the work piece.
- the force results in material compression, which in many materials contributes to better fatigue life and is less susceptible to propagate cracks, with improved resistance to stress corrosion, corrosion fatigue, and cavitation erosion.
- FIGS. 30 a to 30 e Alternative heads that can be used to needle or ultrasonically peen the surface of the work pieces are shown in FIGS. 30 a to 30 e .
- FIG. 30 a shows a head having a continuous wheel or roller and can be caused to apply a continuous pressure.
- the discontinuous roller in FIGS. 30 b and 30 c can be used to apply pressure intermittently and may be preferred to reduce the rigidity required of the machine tool. It is desirable that the machine tool or processing head be supplied with a force feedback mechanism to apply a desired amount of pressure to the work pieces which can be recorded and used in a metrology loop which monitors feedback (including force and work piece temperature gradients) and adjusts the process ideally in real time to ensure consistent treatment of each work piece.
- FIGS. 30 d and 30 e show variations in which an array of wheels or rollers are used.
- the rollers can be arranged to have individual travel so that the rollers can conform to a surface as they travel over it.
- FIG. 31 shows an embodiment in which the processing head comprises sets of arrays of rollers.
- a pair of arrays are arranged to rotate about an axis parallel to the spindle and an array of rollers is arranged to rotate about an axis perpendicular to the axis of the spindle.
- the rollers are arranged to act on an upper surface and side surfaces of a wall part created on the work piece.
- FIG. 32 is a side view of the processing head if FIG. 31 in which the set of rollers arranged to rotate about the spindle axis can be seen more clearly.
- FIGS. 33 to 34 show variations of the embodiment of FIG. 13 and the same reference numerals have been used for the same features.
- a roller is combined with a laser cladding head. This allows for hot rolling of the material immediately after deposition on the work piece. Hot rolling of the work piece can have benefits for the microstructure of the deposited material and can also reduce the amount of force required to affect the material properties.
- the manifold and the processing head are arranged to supply a cooling fluid to internal passageways in the head and to the wheels or rollers to prevent overheating.
- the roller is indexed around the spindle to ensure that the rolling action is substantially parallel with the direction of deposition.
- FIG. 34 shows a processing head having a laser deposition head and peening pins integrated around the head.
- This arrangement allows hot peening, hammering, scarifying, and chiselling of the work piece.
- coolant is supplied to the processing head and is circulated around the head to keep the pins cool.
- the peening is carried out by striking the surface, of the part which is hot, akin to the use of a blacksmith's hammer, and the impact of the pins on the heated metal in a softened state is maximised while the force is reduced compared to cold peening.
- the action of the pins is mechanical and is controlled by the processing head but alternatives such as delivery of the action by the machine tool or by the use of ultra sound can be envisaged.
- the pins can be attached such that they could be displaced with a couple of mm of travel once the appropriate force was exerted by them.
- the pin actuation can be countercyclical to a laser pulsing frequency so as not to defocus the laser if the motion of the pins is dependent on the Z axis of the CNC machine.
- a laser heat source has been shown here as an example, but an arc, electron beam, microwaves, induction heaters, or the like could also be useable.
- FIG. 35 is a variation of the processing head of FIG. 34 and has a processing head having a laser deposition head and peening pins. The same reference numbers are used for the same features.
- the head is shown in more detail in FIG. 36 .
- the peening pins are integrated around the head.
- the head is indexed around to follow a line of deposition, in this head different pins can be activated in order to add pressure in the wake of an area heated by the laser.
- the activation may be by actuation of the peening pins or by a length increase of individual pins so that the contact the surface before the other pins.
- the pins are attached to the processing head such that they can be displaced by a few mm of travel once an appropriate force has been exerted on the pins. It has been found that it is desirable to make the pin actuation countercyclical to a laser pulsing frequency which prevent s the laser defocusing which motion of the pin is dependent on the z axis of a CNC machine.
- the energy source may be exchanged for an alternative energy source such as an arc, an electron beam, microwaves, induction heaters, or other equivalent energy sources.
- FIGS. 44 and 45 show alternative processing heads adapted to carry out two processes.
- the heads in FIGS. 44 and 45 apply a polymer extrusion to a work piece.
- processing head comprises a polymer extrusion head 4400 attached to the tool holder 4402 .
- the extrusion head comprises a body 4404 and a nozzle 4406 .
- the nozzle 4406 is surrounded by a compacting frame 4408 .
- Heaters 4410 are located around the body 4404 of the extrusion head.
- a screw 4412 connected to the tool holder 4402 rotates within a bore 4414 of the head to move injection moulding pellets 4416 from the media feed 4418 towards the nozzle.
- the pellets move down the bore 4414 the pellets are melted by heat from the heaters 4410 around the body.
- the screw 4412 which is driven by the spindle, plasticises the pellet material ready for extrusion from the nozzle.
- the compacting frame 4408 reciprocates up and down applying pressure onto the soft material 4420 in order to achieve full density of the extruded material.
- FIG. 45 illustrates a modification of the head of FIG. 44 .
- the same reference numerals are used for the same features.
- an additional feature is that a continuous fibre 4422 is fed into the head in a co-axial direction.
- the fibre 4422 feeds through the melted polymer and is extruded through the nozzle 4406 with the extruded polymer 4420 .
- a knife 4424 is provided that operates to cut the fiber periodically once it has been extruded. The knife can cut the fibre when it is finished with each continuous feed. In other embodiments the fibre is chopped periodically to produce a chopped fibre reinforcement of the extruded material.
- the polymer and the fibre could be fed from separate nozzles on the same head or could be applied by different heads with the processing heads being switched between the deposition steps.
- the screw does not need to be connected to the tool holder but may be located in the receiving dock or even in the supply dock.
- the polymer may be melted in the machine tool and merely fed to the processing head by means of a heated tube connected or connectable to the body of the processing head.
- FIG. 37 shows a prior art deposition processing head in which an electrode 3701 supplies energy to the work piece 3702 and a wire 3703 is fed into the melt pool 3704 . Typically this is done just ahead of the electrode since feeding the wire ahead of the electrode prevents the wire from snagging on the substrate.
- the area generally indicated at 3705 is the dilution layer and heat affected zone.
- FIG. 38 shows a novel deposition head comprising an electrode 3801 providing energy to a work piece 3802 and a media feed 3803 .
- the head comprises means for generating an integral electromagnetic field 3804 which is arranged to bend an arc 3805 extending between the electrode and the work piece.
- the electromagnetic field 3804 bends the arc 3805 to be slightly ahead of the electrode 3801 .
- the media feed 3803 in the form of a wire can be feed substantially parallel to the electrode so facilitating automation.
- the wire always feeds straight into the weld pool 3806 and is unaffected by changes in the feed direction. Should it be necessary the bend of the arc can be controlled by changing the electromagnetic field applied to the arc.
- the electromagnetic field 3804 can be controlled by changing the mode of the electricity used to induce the field or can be changed by controlling a position of the magnet or magnets.
- FIG. 39 illustrates the control that can be achieved in the location of the melt pool using the head of FIG. 38 .
- the position of the electrode was not changed but the polarity of the field powering the electromagnet was reversed.
- the weld pool location was moved by approximately 10 mm.
- the displacement of the weld pool allows the wire to be fed co axially with the electrode. It will be appreciated that the arc may be intentionally shifted to an alternative position other than a co-axial location of the wire if so desired.
- FIGS. 40 and 41 illustrate processing heads 4001 that can hold various components 4002 .
- the components 4002 are held inside the processing head 4001 in a reservoir or storage facility 4004 and the head 4001 is arranged to dispense the components 4002 as required.
- the processing head 4001 can be replenished through a dock 4006 as schematically indicated at 4008 .
- FIG. 42 illustrates an alternative processing head having a body 4600 and a nozzle 4602 .
- the processing head is connectable to the carriage and has a receiving manifold 4604 located on a side face 4606 of the body.
- the receiving manifold 4604 comprises an opening 4608 having a closure 4610 arranged to be moveable in a track 4612 between a closed position in which the closure is over the opening and an open position 4614 as can be seen in FIGS. 42 and 43 .
- An actuator not visible, is arranged to move the closure form the closed to the open position in the docking operation and to move the closure from the open to the closed position in the undocking operation.
- In the closed position the interior of the processing head is sealed from the environment.
- docking of power and media supplies can be arranged through the opening.
- the path for power and media supply through the opening and into the processing head is sealed from the environment.
