Description

DEVICE TO PROVIDE CONTINUOUS DEPLOYMENT OF PARAMETERS DURING THE MACHINING OPERATION FIELD OF THE INVENTION This invention relates generally to display means for monitoring the process (ie a machine tool and more precisely to graphic display means for monitoring and enabling the best control of the profile of a surface of t down while you're working.

BACKGROUND OF THE INVENTION There are numerous devices for machining work surfaces in workpieces, including grinding machines and grinding machines. In many applications it is convenient to apply a tool to such surfaces to remove the material from the surfaces until reaching a particular contour or profile, such as a cylindrical contour in the case of block cylinders of the motor to row. Some machine tool devices include visual displays of the instant load of the machine, such as the display described in United States Patent No. 4,087,221 which is assigned to the assignee of the present application. The load unloaded is the load on the motor of the machine tool and is simply displayed in a digital or logarithmic scale on a scale that varies from one hundred to one hundred percent, where one hundred percent represents a load. maximum recommended for the engine of the machine has also, some deployments have also included indicating means, such as an intermittent light to indicate when one end of the movement of l (, <s? tera cm. However, as described below, none of the aforementioned deployments has provided sufficient information to allow the operators of the machine tool to easily determine the contour or profile of a work surface while it is being machined. Machine tool will vary according to the profile of the work surface varies, for example, in sharpening operations, when the sites are hard to sharpen, or regions of axial hole that They have a smaller diary than the rest of the hole, a grinding machine finds more resistance and therefore needs more energy to find its way through the tight site. Therefore, when the sharpening machine is sharpening a small diameter region, the instant load of the sharpening motor is greater than when the sharpening machine is sharpening in larger diameter regions of the hole. In this way, the instant load displayed is greater when the sharpening machine is sharpening regions of the hole with smaller diameter. Similarly, in other types of operations of the hei rriential machine, such as grinding operations. the load of the vari-injure machine with the profile of the work surface being machined. When operating machine tool positions that include the aforementioned deployments, the operators of the machine should observe sep- ately the instantaneous load and the position of the stroke in order to determine where the profile of the work surface varies. The operator-is then compensate for such variations in the profile. In particular, in the applications of ailament, the operator-changes the location of the workpiece with r-spec to the sharpening tool moving the work piece along the career ee or moving the machine tool along the career ee, causing more sharpening to take place in smaller diameter regions of the hole. On some machines, the operator may also vary the length of the race. In addition, the operator can stop-or give a dwell time to the stroke action of the sharpening tool while the tool is in smaller diameter regions so that more material is removed from those regions .. In this way, the operator is able to control the sharpening operation in order to achieve the profile of the desired cylindrical hole. There are problems with this instantaneous type of load deployment and operator control. For example, detailed observation for operating the machine so that the obstacle separates the instantaneous load and the position of the stroke can result in errors in the 1 <.; supeificie of work based on the levels of variation of the skill, experience and attention of the operator. In addition, many machine tool devices include only an individual motor to power both the rotation tool and the stroke tool. In these individual motor motors, the energy required to reverse the direction The tool can be registered as a high load point in the instantaneous load display and can cause errors for a variation in the profile of the working surface. Therefore, operators must learn to distinguish between high load readings caused by changes in the direction of the race and those caused by variations in the profile of the work surface. Based on these difficulties, operators can not easily adapt to operate new or different machine tool devices. In this way, the skill of the operator and the amount of attention and experience of it contribute substantially in the cost of machining workpieces and in the precision and uniformity of the parts produced. Recently, the environment of the workplace has tended toward the accomplishment of multiple tasks. Each time it is required that each worker learn to perform a tai a in a particular work environment in order to increase the overall efficiency of the workplace. The above mentioned mechanical tool machines do not facilitate this tendency due to the difficulty involved in learning to operate the machine tools and the difficulty involved in achieving uniformity in the work piece between different operators of the machine. As a result, it is convenient and advantageous to provide a machine tool that allows an operator of the machine to easily determine the perf of a work surface that is being machined. It is also desirable and advantageous to provide a machine tool that efficiently reduces the probability of errors or variations in the profiles of the work surface. A main object of the present invention is to provide a machine tool display of the profile of a work surface while it is being machined. Another object of the present invention is to reduce the time and cost associated with the training of the operator of the machine tool. Another object of the present invention is to provide a graphic display of a machine tool that represents the profile of a work surface while it is being machined. Another object of the invention is to provide a machine tool having a stroke and rotation tool in which the rotation of the tool receives its energy from a motor ^ \ spindle which is independent of the tool of a \ '\ O 'to . Another object of the present invention is to provide a graphic display of a machine tool that continuously displays the position of the stroke on an e and the load of the machine tool on an axis perpendicular to the position e of the stroke. Another object of the present invention is to provide a graphic display of the tool that continuously displays the position of the tool on a first axis or a function of the load of the machine tool on a second axis perpendicular. to the first axis, and a mirror image of the relationship around a third axis that is parallel to the first axis so that the profile of the work surface is displaced.

BRIEF DESCRIPTION OF THE INVENTION These and other objects and advantages of the invention are realized by means of a device which, in one embodiment, is a machine tool deployment device that provides a continuous real-time display of a graphic representation of a work surface profile during the machining of the work surface. The machine tool includes a position sensor that detects a position of a tool with a specific surface and a load sensor that detects a tool load such as a load on a motor. I n the position sensor '-or loading sensor' connect processing means, such as a microprocessor, which is attached to a visual output device, which is capable of displaying information in a system of two coordinates and that controls that device. The processing means coordinates the data received from the position sensor and the load sensor and sends an output signal to the output device so that the provided display is a continuous load display as a function of the load. position, the load deployed on an ee against the position of the tool on an ee perpendicular to the load axis. The graphic display represents a cross-sectional profile of the working surface or while it is being machined. The present invention allows an operator of the machine tool to easily determine the profile of a work surface while it is being machined. In addition, the present invention has many advantages over prior art machine tools and deployment devices, such as greater ease with which an operator can determine the work surface profile, greater precision in making such determinations, increase in the uniformity of the machined workpieces, and reduction in the level of skill, experience and time of training required for operators of the machine tool. These advantages are apparent from the description of the present invention in the context of an ailing operation. The deployment device of the present invention is suitable for use in sharpening machines. However, it is contemplated that the release device of the present invention is useful in numerous types of machine tool devices and may be incorporated in such positives. In an ailing operation, a grinding machine located at the end of a spindle end is glued simultaneously into a hole and runs axially along the length of the hole. As the sharpening tool rotates and cuts axially, it also engages the inside surface of the hole, removing material from it. Two engines are provided. A stroke motor to give power to the axial stroke of the grinding machine and a spindle motor to give power to the rotation of the grinding machine. This separate motorized configuration allows the energy or load associated with the rotation of the sharpening tool to be isolated from the energy or load associated with the stroke of the sharpening tool. In vertical sharpening applications, the deployment device of the present invention provides a real-time and continuous display of detected spindle motor load versus detected axial stroke position.

The position sensor detects the axial position of the sharpening tool or the hole and the load sensor detects the load on the spindle motor. For these purposes various position detection devices and various known charge detection devices can be used. Each sensor is connected to the microprocessor or other display device that coordinates the data received from both sensors and controls the visual output device. The microprocessor is programmed to transmit the device of visual output to display the load of the screw motor on a horizontal axis against the axial stroke position on a vertical axis as well as a mirror image of the relation around a second vertical axis. The graphic display represents a cross-sectional profile of the hole while sharpening. The lathe operators can use the graphic display during a sharpening operation to easily achieve a predetermined final profile of the hole. For exampleWhen a cylinder in the engine block is sharpened in which the desired final profile of the cylinder is cylindrical, smaller diameter regions of the cylinder are represented in the graphic display so that the operator of the machine tool can easily recognize them. In addition, the display changes continuously in real time as the grinding machine runs so that the operator knows the axial position of the sharpening tool observed in the display. The operator of the machine then adjusts the axial position of the engine block, adjusts the action do (; arr < .? - a do The sharpening tool stops the axial shaft of the sharpening tool on the regions of the hole with '. smaller diameter. By controlling the sharpening operation in this manner, the operator causes the additional material to be removed from the interior of the surface of the hole in the smaller diameter regions. The diameter of the region increases in this manner resulting in a consistent diameter along the axial length of the hole which, therefore, is reflected in the deployment. The graphical display increases the ease of operation of the machine as well as the ability of the machine operator to achieve the predetermined final profile of the hole. 5 It is agreed that the deployment design can be incorporated in vertical grinding machines, horizontal silating machines, vertical grinding machines, horizontal grinding machines and other machine tool devices in which the determination or profile of the machine is convenient. One piece work surface below. It is understood that in some applications of the present invention it is convenient to invert the graphic display so that the load is displayed on the vertical axis and the position is displayed on the horizontal axis. In addition, a computer controlled machine can be programmed to automatically respond to load sensor data and to 1 l the data of the position sensor with the iin of achieving the predetermined final profile of the work surface. The advantages of the present invention will be apparent to those skilled in the art after considering the following description in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS The present invention relates to a novel deployment device for use in various types of machine tools, including sharpening machines and machines grinder-as. To three birds of the description of the aforementioned drawings the deployment device is described in terms of its application to the sharpening machines and, more particularly to vertical sharpening machines used to sharpen holes such as cylinders of the engine block. The application of the vertical grinding machine of the present invention is for purposes of illustration.

Fig. 1 illustrates a cross-sectional view of an engine having a cylinder bore 10 i on a vertical axis 12. an interior surface of the hole 10 is represented by side walls 14 and 16 of the profile. A desired final profile for the hole 10 is cylindrical in which the Side walls 14 and 16 are substantially parallel. However, as illustrated, the hole 10 tapers from an upper surface 18 to a lower surface 20 having a diameter of 10 cm. ro greater near the upper surface 18 than near the lower surface 20. The amount of tapering illustrated is exaggerated to facilitate understanding. Three positions are indicated along the axial length of the hole 10 in 22, 24 and 26, the first position 22 having a diameter greater than the second position 24, and the second position 24 having a diameter greater than the third. position 26. During a sharpening operation, it is convenient to remove the material from the inner surface of the hole so that each of the first, second and third axial positions 22, 24 and 26 has the same diameter when the sharpening operation is completed . In order to achieve this final profile, more material must be removed from the hole positions with a diameter smaller than that of the largest hole in the hole. As described below, the deployment device of the present invention aims to simplify this task for the operator of a sharpening machine in comparison with the deployment devices the technology ar.tenor. Figures 2A-2C illustrate a deployment of the prior art Ladera 20 machine. Deployment 20 includes a horizontal digital display screen at 30 and a corresponding horizontal scale b 32 ranging from 0% to 100%, where the scale values represent a percentage of a maximum recommended load for a machine particular sharpener. In Figure 2A, the display value 34 represents an instantaneous load of the grinding machine when a sharpening tool in a first position 22 of the hole of figure 1. In figure 2B a deployment value 36 of an instant load of the sharpening machine is shown when the tool is placed in a second position 24 of the hole of the figure 1. Similarly, Figure 2C shows L5 represents a deployment value 38 of a vertical load of the grinding machine when the grinding tool is placed in a third position 26 of the hole in figure 1. As shown, the instantaneous load of the grinding machine is greater when the Sharpening tool is placed in 0 hole positions with small diameter rnas. The deployment 28 may also include a peak load display 40 as shown in Figure 2B. Peak load 40 represents the highest car-ga value for a running sequence. When the sharpening machine is operated including the deployment 28 of FIGS. 2A-2C, the machine operators should observe separately the instantaneous load readings 34, 36, 38 and the positions of the axial stroke for the purpose to determine where the hole profile varies. Detailed observation by the operator of the machine is required to observe the instantaneous load and the position of the stroke and a lack of attention may result in errors or variations in the final profiles of the hole. The operator of the machine can also observe the peak loads 0 of the deployment 28 and try to minimize the variation of the load away from the peak 40 in order to achieve a cylindrical hole. In addition, some known prior art sharpening machines have only one individual motor to power both the rotation of the tool and the stroke of the tool. In these individual motor sharpening machines, the energy required to reverse the direction of the tool stroke is usually recorded as a high load point in the instant load deployment and can result in errors for hole regions. 10 with smaller diameter. Therefore, the operator of the machine must learn to distinguish between high readings caused by the change of direction in the race and those caused by variations in the profile of the hole 10. The deployment device of the present invention effectively eliminates these problems and, therefore, has advantages over the prior art display devices 28. Figure 3 illustrates a display 42 in accordance with an embodiment of the present invention. A deployment screen 44 included a vertical axis 46 which represents the axial length of the hole 10 of Figure 1 and a horizontal axis f8 representing the car which ranges from 0% to 100% of maximum recommended load. Contrary to the deployment 28 of FIGS. 2A-2C, the display 42 continuously deploys ins ante load lines 50 for numerous positions along the axial length of the hole 10. In particular, the instantaneous load values at positions 52 , 54 and 56 corresponding to the first, second and third positions 22, 24 and 26 respectively of figure 1, are displayed, together with numerous positions between them. The resulting deployment effectively depicts a profile of the side wall 14 of the hole in Figure 1. An alternative deployment 58 is illustrated in FIG. 4. The display 58 includes a screen of deployment 60 having first and second deployment areas 62 and 64 separated by imaginary axes 66 corresponding to the ee 12 of the hole of figure 1. The deployment area 62 includes an identical deployment to that of figure 3. The second deployment area 64 provides a mirror image of the first deployment area 62 about the imaginary axis 66. The resulting display effectively depicts a cross-sectional profile of the hole 10 in Figure 1. The deployments 42, 58 can also include a vertical peak load line 68 that corresponds to the highest load value in the deployment. The vertical peak load line 68 is plotted one per-run and improves the ability of operators to detect small differences in the horizontal lengths of load lines 50. Each line of instant load 50 on figure 3 and Figure 4 corresponds to a particular axial position of the hole represented by the position axis 46. The 1 load meters 50 are shown vertically apart for clarity, but they can also be displayed adjacently giving the appearance of a continuous surface .. The number of load lines 50 displayed depends on the number of axial positions in which the load is measured. In addition, the deployments in accordance with Figure 3 and Figure 4 are provided in real time and in this way the work is simplified so that the operator identifies the variations in the [>]; erf? l of the hole. Deployments 42, 58 change in real time. As the stroke of the sharpening tool-a, the axial position in which the unfolded load is changing indicates the axial position of the sharpening tool at that particular instant. Therefore, as described in more detail below, the operators of the machine only need to observe the deployment 42 or 58 when performing a sharpening operation and consequently the level of skill and attention required of the operator is reduced. and their ability to uniformly sharpen numerous parts increases. Figure 5 is a partial illustration of a machine l! typical vertical grinding machine 70. The grinding machine 70 includes a spindle motor 12 operably connected to a limb 74 having a sharpening tool fh secured thereto and located within a hole 78 in a motor block b 80. During a sharpening operation, the sharpening tool 76 is rotated simultaneously within the hole 78 and runs axially along the length of the hole 78. Conforming The sharpening tool 76 rotates and runs axially, the abrasive stones 82 or other sharpening materials The abrasive, they attach the inner surface 84 of the hole, removing the material from it. It is contemplated that the sharpening tool 76 could take the form of various sharpening tools known holes. As the sharpening tool 76 rotates and runs axially, the operator of the machine observes the deployment of the present invention. The regions of the hole with smaller diameter are compensated by axially moving the engine block 130 so that greater sharpening occurs in such regions. Similarly, the action of the race of the The grinding tool 76 can be adjusted so that sharpening takes place in the smaller diameter regions or the stroke action can be stopped in the smaller diameter regions. The axial position of the burnishing tool 76 within the hole 70 is represented by the area 5 of the display that is changing so that the operator knows when the sharpening tool 76 is located in the smaller diameter regions. It is possible to achieve that the action of the stroke of the grinding machine 70 is stopped by pressing a button of permanence. The deployment devices according to the present invention allow an operator to determine, observe and compensate for variations in the profile of the hole with greater precision and consistency than in the case of prior art deployment devices due to the representation n graph of the profile of the hole. The spindle motor 72 '\ a power to the rotation of the sharpening tool r? and a separate stroke motor, not shown, energizes the axial stroke of the sharpening tool / b. However, it is contemplated that an individual motor * can be used both for rotation and for the race. Several known motors can be used to power the spindle rotation or the axial stroke taL such as electric motors, hydraulic motors or pneumatic motors. Figure 6 illustrates in block diagram form a description of the deployment device of the present invention. A load sensor 86 communicates a detected load with the microprocessor 88 acting as a display transistor. Numerous known detection devices can be used such as power or current sensors which include, but are not limited to, one or three elements of the Watt transducer, a current transformer, a current / power Hall effect sensor, or an auxiliary output of a rnotor transmission controller that interferes the load on the motor-monitor by triggering an internal signal. Other types of sensors may also be contemplated, such as energy sensors or mechanical torque including, but not limited to, a torque transducer or strain transducer? ezoelectp co or magnetoest pct ivo. Similarly, other forms of deployment transmitter may be used in place of my oroprocessor 88. For example, a specific application integrated circuit (ASIC) could be used to drive the visual output device 92. n communicates to the sensing device 88. In the detected position again, several known position detection devices including, but not limited to, an optical encoder, a potentiometer, a linear variable differential transform, a muctosin or a Hall-effect sensor could provide effective results The microprocessor 88 is programmed to coordinate the load sensor data and the position sensor data and provide an output signal that drives the visual output device 92 as described in more detail below Several known visual output devices can be used, including an LCD liquid crystal device, a CRT cathode ray tube device, an LED device, a plasma discharge device or an elect rolum device, but is not limited thereto. The resulting device returns the shape of the device shown in Figure 4 or alternatively in Figure 3.

Figure 7A is an illustration of the deployment device as it is implemented in the operation of the vertical sharpening machine. The load sensor 86 is incorporated in a variable AC frequency transmitter '94 which obtains its energy from the power source 96. The load sensor 86 supplies an analog signal of 0 to 5 volts at a vertical amplifier 90 with a gain of 1, providing rejection and isolation of the detected load. The charge signal then passes through a low-pass filter LOO, such as a two-pole Butterworth filter with a cut-off frequency of 20 H, before reaching the microprocessor-08. The microprocessor 88 includes a converter "analogous to vertical 102 built-in which then converts the load signal from 0 to 5 volts into one byte. The position sensor 90 includes a square-pulse encoder 200-per revolution that is mechanically attached to the stroke mechanism. The encoder pulses the trip to an integrated circuit 104 that translates the pulses into a two-byte digital word that the microprocessor '88 can read. The digital word is a value between 0 and 799 and is proportional to the number of travel grabs of a driving shaft in the stroke mechanism. The half-scale, value-is 400, of the digital word represents the downward stroke and the other half represents the upward stroke, so that the axial position itself of the sharpening tool 76 den of the hole 78 is represented using two different digital words that depend on the IT address axial on which the sharpening tool 76 is traveling Figure 7B illustrates another implementation of the vertical sharpening machine operation deployment device In this implementation the load sensor 86 includes a phase watt transducer. individual to read the energy that goes to the alternating current transmitter 94. The resulting signal is a current 40 to 20 mA that passes through a convert 106 that converts the signal into a signal of 1 to 5 volts before entering the universe. If the resistor is 98. The converter 106 is a resistor of 250 ohms and the signal that enters the differential amplifier 98 is a voltage measured through the resistor.The microprocessor 88 processes the load and position data in a similar manner. - for both modalities of Figure 7A and 7B Figure 8 is a graphic illustration of the processing microprocessor 88. The graph starts with the block of the starting device 100 which triggers the readings of the oques 110 and L12. The position reading block 110 reads the signals from the position data while the load reading block 112 reads the load data signal. The speed at which the microprocessor 88 reads the load and position data must be fast enough for a given stroke speed to plot a sufficient number of load lines 50, see FIGS. 3A and 3B to provide a representation of the hole 78. Then the position and load signals are modified in blocks 114, 116 and 118. The conversion block 114 converts the digital word L representing the position into a number between 0 and 99, representing the relative position of the tool afi Hillside 76 within the hole 70, without taking into account The direction of the axial stroke. The converted position number 0 represents the upper part of the stroke or the upper part of the hole 78 and the converted position number 99 represents the lower part of the stroke or the hole part 7B. The scale block l LE. Scale the byte representing the charge to a number between 0 and 128 and any antecedent or deviation in the byte of charge is subtracted so that when there is no shear load on the machine, the byte of load will be 0. With respect to load values in scale, additional adjustment of the values may be necessary due to the variations caused by the different directions of the stroke. For example, in the embodiments illustrated in figure ff and 7B the load data detected for a particular axial position of the hole in a downward stroke are different from the load data detected in the same position in an upward stroke. If the difference is large enough, the deployment fluctuates as the sharpening tool 76 runs up and down and the deployed profile appears to move inwardly and outwardly relative to the imaginary axis 66, as best seen in FIG. 4. FIG. has determined that the amount of fluctuation can be reduced sufficiently, but not excessively, by programming the inproportion of the load in spite of the load on the scale in the weighting block J18 of conformity <; on The following formula.

Heavy value = Value in scale -5- 3 (Previous value stored) 4 The storage block 120 then stores the heavy load value in a frame. The stored value is classified in the table by the converted position value, then the stored load value is plotted onto an LCD liquid crystal display screen in which a series of contiguous horizontal pixels are displayed. which form a horizontal bar graph. The vertical location of the bar graph on the liquid crystal LCD screen is determined from the value-of the data included in the table. The graphing routine is described in more detail below with reference to FIG. 0B "The decision block 124 determines whether or not to continue the position reading and load values. If the sharpening operation is still being performed, the processed position and load values are read and plotted again, but if the sharpening operation is completed the routine ends as indicated by the termination block 126. Figure 8B is a graphic illustration of the graphing operation for a deployment in accordance with the display shown in Fig. 4. The start block of the IbO graining signals the start of the graining operation. The erase block 152 then erases the load line 50 displayed at the left and right sides of the screen, which remain from the last graph for the indicator position. The graining block 154 graphs the new stored values from left to right instead of the load values that were just erased on the left side of the screen. Fl block of graph 156 then graph the new stored value from right to left instead of the cleared value on the right side of the screen. After the left and right graphs, the decision block 158 determines whether or not the indicated position represents the top * of the hole 76. If so, the deletion block 160 deletes the vertical peak line 68 left and right previous and the plot block 162 graphs a new vertical peak line left. Similarly, the graphing block 164 graphs a new vertical right peak line. The graining operation is then completed as indicated by means of the final block 66. The graphing operation described above results in a deployment in accordance with Figure 4. The operators of the sharpening machine can use the display during the sharpening operation for easy operation.

-J K achieving a predetermined final hole profile as previously described. The operators of the sharpening machine only need to observe the deployment of the present invention when they perform a smoothing operation and therefore the level of skill and attention required for the operator is reduced and the skill of the same to sharpen. 5 uniformly numerous parts is increased.

In particular, a machine tool display of a work surface profile is provided as is, *, machining. In addition, a graphic display of the machine tool is provided, which continuously displays the load of the machine tool against the position. Although the invention has been described and illustrated in detail, it will be understood more clearly that the The same has as its sole purpose illustration and example and should not become a limitation. For example, it is contemplated that the graphic display of the present invention is not limited to vertical sharpening machine applications and may be incorporated into other machine tool applications that include horizontal grinding machines as well as vertical and horizontal grinding machines, including various tools to remove the material from the work surfaces. Furthermore, it is contemplated that the block diagram illustrations of FIGS. 7A and 7B will only be and there are numerous possible configurations for implementing the present invention.
