Description
The present invention relates to have process equipment, lathe for example, processing station and method of operating thereof.
Be the control process equipment, for example lathe normally adopts digital control (NC) recently, and the most frequently used then is computer control or computer numerical control (CNC) (CNC).The purpose of these controls is the axle runnings that make process equipment according to the instruction and data by keyboard, data carrier (for example perforated tape reader, plastic flexible disc) or data channel (for example Serial Transmission Chains) input, processes and control process.
Determine each input parameter of NC or CNC control device, its expense can be very big, and this depends on process in the requirement of physical dimension and technical elements and decide.Therefore in order to calculate input parameter, people adopt the method for computer-aided manufacturing (CAM) usually.The CAM processing station is worked out needed data by means of the application programming language relevant with relevant issues and processing technology, and these data normally are sent to NC or CNC control device by data carrier (circuit outer) or data circuit (on the circuit) with the form of the most frequently used code speech unit (ISO or EIA sign indicating number).
NC or CNC control device are to be used for controlling or the adjusting time is the treatment capacity of determinative and the working order of equipment.Because these control device can not carry out the calculation task hard work, and because the display resolution characteristic deficiency of these control device, there be not the application programming language relevant with relevant issues, therefore the data structure of not representing workpiece and machining physical dimension etc. changes the limited in one's ability of machining geometric condition by the intervention to NC or CNC control device in process.
On the other hand, the CAM processing station is fast inadequately to the repeatedly interruption reaction relevant with technology that program recurs fast in process, thus they to be not suitable for the control time be the treatment capacity of determinative and the working order of equipment.
From " Verein Deutscher Ingenieure magazine " the 875-878 page or leaf of 1986 the 128th the 22nd phases of volume and from " weapon technology workshop " 129-133 page or leaf of 1987 the 77th the 3rd phases of volume, people can know the CAM processing station is connected to the situation that a programing system carries out NC or CNC control.In the prior art, programing system produces standardization NC control information according to DIN 66025 Deutsche lndustrie-Norms, and this information must be transported on NC or the CNC control device in some way.Therefore be not directly to get in touch between CAM processing station and NC or the CNC control device.In these cases, in view of being sent back the CAM processing station from programing system, any data do not have any meaning, thereby only get in touch usefulness between CAM processing station and the programing system for the one-way transmission data, only be to transmit in the direction of CAM processing station to programming station, these characteristics can also the direction of arrow be understood in described photomechanical printing reference accompanying drawing.These two parts of reference instructions will keep the independence of each system as far as possible in addition, and they and existing general structure are coupled (referring to " Verein Deutscher Ingenieure magazine " the 128th page, left hurdle, second section, " weapon technology workshop " the 131st page, the 4th point).This external " weapon technology workshop " the 131st page also recommends the IGES or the 4PT formula interfacing equipment that can not carry out any real-time interactive process control in the 4th.
Can know that from European patent EP-A-0109742 the data that programming station is produced are sent to the situation that NC or CNC control device use for this device.In the prior art, the transmission of data still only from programming station to NC or the direction of CNC control device carry out.By the way, this programming station is not a CAM processing station fully, because it can rather than determine each input parameter of NC or CNC control device according to the requirement of the geometric condition aspect of processing technology according to the requirement on the technology.
Certainly, can also recognize that from European patent EP-A-0109742 and EP-A-0086843 employing also can be used as the transmission data of contact between programming station and NC or CNC control device of two-way operation circuit (bidirectional line, " bus ").In the prior art of European patent EP-A-0109742 and EP-A-0086843, this bidirectional line is must not be in order to set up real bidirectional data exchange between the process computer of programming station and NC or CNC control device, they can only be used for making data to circulate in a direction or another direction between each a special-purpose process computer and an i/o controller on demand, so that get in touch with data-carrier store.In the prior art of European patent EP-A-0109742 and EP-A-0086843, the transmission of data between the process computer of the process computer of programming station and NC or CNC control device is from programming station to NC or NC control device and unidirectional carrying out on the direction of NC or CNC control device all the time.
In addition, can see getting in touch of being set up between programming station and NC or the CNC control device from European patent EP-A-0109742 and EP-A-0086843, these contacts only allow data circulate between the process computer of the process computer of programming station and NC or CNC control device sometimes, and do not allow data circulate sometimes, in other words, at this moment get in touch interruption between the process computer of the process computer of programming station and NC or CNC control device.
Therefore prior art did not propose at the process computer of NC or CNC control device fully and carried out the practice of mutual process interface exchanges data between the process computer of the programming station of its upstream or CAM processing station.
Aspect keyboard and display, European patent EP-A-0109742 introduce also just selectively rather than side by side lead to the contact method of programming station or NC or CNC control device.
Therefore remove haply at the CAM processing station to the direction of NC or CNC control device, between CAM processing station and NC or CNC control device, circulate inconsistent with prior art in other direction vectoring information.In other words, prior art only is taught in process operation and uses the CAM processing station before beginning, and with the use-pattern of the process interface formula of the CAM processing station of NC or CNC control device cooperating will be inconsistent with prior art.
Especially, with usually on equipment generally in order to process and any instant condition relevant with the machining geometric condition of existing process operation and/or Machining Technology feed back to the CAM processing station from NC or CNC control device may be contradictory with prior art.As mentioned above, the CAM processing station is handled the usefulness that the data that produced are actually can not must be enough to transfer them to NC or CNC control device confession any significant purposes in existing process soon on time.
Therefore prior art has been got rid of the possibility that the Processing tasks with the Processing tasks at common CAM station and common NC or CNC control device distributes and allocate each corresponding processor of CAM processing station by the mode beyond the traditional approach.By traditional mode, whole tasks of CAM processing station are to be handled by the processor of CAM processing station oneself, and all tasks of NC or CNC control device are to be handled by the processor of NC or CNC control device oneself.
No matter how to say, the Processing tasks of common CAM processing station be transferred to common NC fully or the CNC control device is impossible, because with regard to data volume, common NC or CNC control device are the tasks of can not handle common CAM processing station.In addition, in any case also the Processing tasks of common NC or CNC can not be transferred to common CAM processing station fully, because common CAM processing station incident at least just relevant with technology, that time factor plays a decisive role is to react with enough fast speed.
The purpose of this invention is to provide a kind of useful performance and combine comprehensive solution to the problems described above common NC or CNC control device and common CAM processing station, make on the equipment generally in order to process and any instant condition relevant with the machining geometric condition of existing process operation and/or Machining Technology can both feed back to the CAM processing station from NC or CNC control device, handle at the CAM processing station, and the feasible process that made is at that time carried out required data and/or is instructed in time being sent in NC or the CNC control device.
Compiling in processing station of the present invention has following equipment: a process equipment; One NC or CNC control device comprise the process computer that wherein is equipped with; One CAM processing station comprises the process computer that wherein is equipped with; Single control desk is equipped with monitor keyboard and can establishes the printer that can not establish, for the usefulness of carrying out man-machine interaction with NC or CNC control device and CAM processing station; With a two-way data transmission link (bidirectional line, " bus "), for the usefulness of between two process computers, carrying out bidirectional data transfers.
Therefore the embodiment of processing station of the present invention has such advantage: all do not relate to, and the time is played the treatment capacity of determinative and function that equipment carries out processing action can be sent in the CAM processing station.This has further promoted rationalization, and has reduced expense, because NC or CNC control device only need be handled the partial function of common NC or CNC control device, thereby can make simplyr.In addition, this can be avoided repeatedly repeating to import identical or similar data, for example, numeric data code is become the form of NC or CNC with numeric data code from the format conversion of CAM by Deutsche lndustrie-Norm DIN66025 for example, can also avoid ambiguous meaning and consequent error source.
In a word, exist two independently " fields " so far, i.e. " CAM field " and " NC or CNC field ", and the present invention might transfer in " CAM field " " NC or CNC field " bigger equipment, thus transfer to craft interface device and be transformed into language.The embodiment of processing station of the present invention comprises the two-way connection that embodies real-time change process between CAM processing station and NC or the CNC control device now.Simultaneously actual NC or CNC control device are cut down " incomplete " control because the task with traditional of some part of NC or CNC control device system by the CAM processing station on behalf of execution, this has brought the effect of remarkable rationalization.
Preferably be at least when process equipment is worked, two process computers for good and all are connected to each other, and control desk is permanently connected on two process computers.
A benefit of doing like this is, must data presented all can be simultaneously displayed on the individual monitor by means of general window technique from the CAM processing station with from NC or CNC control device.By contrast, in the prior art, operating personnel must see two displays simultaneously, one of respectively having of these two displays is that branch is tasked CAM processing station and NC or CNC control device, perhaps press the mode of this prior art of European patent EP-A-0109742, operating personnel must task the display branch from the data of CAM processing station or from the data of NC or CNC control device, and the data presentation that refusal will not assigned is come out.

Process equipment is lathe preferably, particularly the lathe of borrowing galvanic corrosion (spark erosion) that workpiece is processed.
Preferably at least when process equipment is worked, the bidirectional data transfers circuit is devoted oneself to work, will belong to process equipment, wherein employed instrument and/or wherein the information of employed workpiece transmitting from NC or CNC control device to the direction of CAM processing station.
The present invention operates the method for processing station, it is characterized in that, the process computer real time execution of NC or CNC control device, and handle the treatment capacity that at least a portion time plays determinative, the process computer of CAM processing station is then handled all amounts of calculation greatly but be not to be the treatment capacity of determinative with time.
The benefit of doing like this is, transmitting all toward the CAM processing station can need not repeatedly to repeat to import identical or similar data when not relate to the time be the function of treatment capacity and the process equipment of the determinative action of processing, for example numeric data code is become NC or CNC form by for example Deutsche lndustrie-Norm DIN 66025 from the CAM format conversion, thereby also can avoid ambiguous meaning and error source.
Preferably also the processing section time is played the treatment capacity of determinative to the process computer of CAM processing station.In other words, if the process computer of CAM processing station compiles because of it and the mode that be coupled is worked very soon, then the CAM processing station also can be in order to the process computer calculating real time problem of assistance NC or CNC control device.
The benefit of doing like this is that the process computer of CAM processing station receives recently about the machining geometric condition of existing processing technology and the information of technical requirement.Simultaneously, the process computer of CAM processing station is handled a large amount of processing technology data, thereby makes it can intervene existing process.For example, particularly when process equipment be when borrowing electrocorrosion (spark erosion) processing work, the process computer of CAM processing station can adapt to process when changing the parameter of pulse producer, or make the process optimization, method is to change geometric data when reducing radius, perhaps also can change so-called bleed strategy (escape strategy) when particularly washing condition is unstable in the process instability.
When process equipment is a machine tool, when particularly borrowing the lathe of electrocorrosion (spark erosion) processing work, in a most preferred embodiment of technology, the bidirectional data transfers circuit transmits relevant process equipment, the wherein employed instrument and/or the information of employed workpiece wherein in the direction from NC and/or CNC control device to the CAM processing station at least during part-time.This information is represented machining geometric condition aspect and the technical requirement that existing processing technology is existing in fact, its feedback toward the CAM processing station be except data and/or the instruction before process begins from NC and or CNC control device to CAM processing station carry out carrying out the general transmission.
In other words, before process began, circuit was in normal way in order to data and technical data about workpiece and machining geometric condition are sent to NC or CNC control device from the CAM processing station.Also work (this may do because of the occasion that the cost relation is restricted like this at NC or CNC control device interior storage capacity) of this circuit in addition in order in process, to reinstall and to upgrade above-mentioned the sort of data, and be used between NC or CNC control device and CAM processing station how much of exchange machinings and technical data, this just might utilize each capacity of each process computer in the mode of the best, thereby also can make the data itself that exchanged reach optimization.
The benefit of doing like this is, concerning processing station corresponding to the part of CAM processing station and processing station corresponding to the part of NC or CNC control device, can adopt same display, same keyboard, with a kind of application programming language, and adopt reciprocation usually with a kind of form.
