The reference tracker performs an initial calibration and the recalibration process recalibrates. Through a machine tracker in the machine control program is the correction data, they are stored and used by the post, grinding or erosion process, in order to correct 96 ^) Japanese repair (history) is a technical page grinder or erosion machine Axis displacement. The recalibration can be performed automatically from time to time as needed, so the recalibration leads back to the initial calibration in its accuracy. The initial calibration is preferably performed by a reference tracker attached to the workpiece carrier. Attach a tea test body on the processing spindle rather than on the invading or grinding tool. When this is done, the reference body is tracked multiple times by reference to the tracer. In this case, for each coordinate direction χ, γ, ζ respectively, at least one tracking procedure is carried out, which corresponds, for example, to the corresponding adjustment direction of the positioning device acting on the workpiece carrier or the machining spindle carrier. An initial measurement is obtained for each coordinate direction. Explicitly speaking, the measured value is obtained by the calculation of the position value provided by each adjustment device assigned to each coordinate = the known three-dimensional coordinate of the test disk or the reference tracker. However, the measurement obtained in this way is only a first approximation: because ^ in this mode, it is generally not possible to know the switching point of the switchable reference tracker. Therefore, in order to calculate, the switching point of a tracker is first randomly assumed and a section for all the seats' is calculated under the assumption that the assumption and the known reference disk and tracker size and the coordinate value of the f-part are Correction value Δχ,, heart. The positive value of this time should indicate incomplete positioning, due to the structural inaccuracy of the machine frame and the guiding elements, and: changes in the direction of each coordinate. The correction value is stored in a control device or a memory corresponding to the control device. A grinding test is now carried out in the second step, in which the stored correction value is corrected by the correction control command of the device. The positive value is added to the predetermined coordinate direction for the grinding test with a proper symbol to slightly grind a test piece during the grinding and testing process, especially %竿) month A repair 8 positive amount for t to be inspected The coordinates are ground in two directions. Grinding section Tests the small facets that are ground on the surface of the workpiece. The two grinding _ faces belong to the same coordinate and are arranged adjacent to each other by different lining directions (ie + χ and - sanding). The positional error between the +X and 1 is determined by the difference in size. If the two facets are two lan:: There is a position error. If the two facets are different in size, then the 0-inch difference is pushed out - a correction value ^ kiss, ^ and saved =: inside the unit. Then proceed to the second The secondary grinding test is still evaluated by ί _ d—the iteration is repeated until the same size of the facet is ground in the respective 钵 direction. In this way = early-the coordinates such as \ coordinates Perform this iteration over (4) = at least when the reference tracker is at its same for all of the tracking pins, and the lateral deflection has the same switching point position. For the X-seat (or other coordinates selected) Tracker correction: his existing coordinates. People use it once they are researching or invading the way to get their pure alignment by making the test workpieces located in the machine contact with the machine and immediately and sequentially Recalibration, the correction obtained in the measurement. They: vertical = measurement deviation of the reference tracker. Subsequent recalibration; measurement by the repair field of the fresh material. If the case X, Y, Z#.m Δχη, ΛΥη, ΛΖη^, ^ Δχδ, two, some The deviation indicates that, for example, the size of the casing due to temperature changes is considered in further processing. The advantage is that the reference tracker is used twice or at least ==: Γ times and switched in chasing The value handles the _point of the vertical sales. It is used for the subsequent measurement of the second part of the above purpose. The machine is equipped with 4= and a machine chasing and crying, and by the ._ dry shelf And two: the parts are attached to the processing spindle support 10 "抒f 2: connected to the workpiece carrier. In addition, the machine has a two corresponding control software 'the control software can pass in the - = quasi-pull Refer to the tracer for the calibration process and the above recalibration can be performed in the -4 and quasi-nuclear modes by the corresponding machine tracker. The control software performs the above steps 'where it is required by the operator at 15 = process ( Input data in the initial calibration. These inputs are the simplest In the case of t-month, it may be the estimated value Δχ of the dimensional deviation, which is caused by the difference in the facet size produced in step 2. The machine adjustment expert must provide a =2 rationality estimate, but it can also be in the control software. Set a speculation a 'It can be inferred from the difference in the size of the facet to estimate the correction value Δχ (or no or 20 △ small. Here the speculative model is based on the assumption that the larger between the faces The size difference is configured with a larger correction value = trend. In the simplest case, a proportional relationship is assumed and used as a basis. [Description of the Drawings] • 9- 1339147 ------- A year.

The grinding head 3 has a machining spindle i2 grinding tool, such as a grinding wheel, for machining the workpiece: the rotational axis that can be attached to the force is parallel to the 丫 direction ^ 卫 spindle 12 set - a machine Tracker 14 °. Second, a test piece ι6 #/μ state on the polishing head 3 has a tracker component carrier 4 for tracking the workpiece a. The 洌_trial core workpiece is fixed on the workpiece carrier 4, such as a ball fixed to the workpiece U and a tracking lock for the tracker and/or the tracking ball. The workpiece "has a track of a workpiece, such as a cylindrical burr"; one for a grinding process to make a drill bit or he and the wool is thus used in the grinding machine 1 Perform the following calibration. -11 - 20 As shown in Figure 2, the axis 12 is attached to the ', and the initial calibration is performed. The machining head of the polishing head 3 is cut, for example, the reference disk 18幵. Body, and attached to the workpiece comer, self, = guana body 17 - a reference tracker 19. This is a measurement tracker that can be switched = = = ί. Its tracking pin 21 turns and moves. As shown in Figure 3, the test pin rotates about a pivot D when laterally deflected. 'Coursie 18 and reference tracker 19 are fixed in the grinding head 3 and the grinding head control device 7 to move up to the height of the workpiece carrier 4 in a calibration operation mode, and the control is placed on the workpiece. The tool 4 is driven toward the polishing head 3 in the X direction so as to pass through the tea tester 19 to track the reference disk 18, as shown in FIG. For this purpose, the workpiece carrier 4 is replenished around the sister line A so that the tracking pin 1 extends in the X direction. When the tracker reaches its switching point, the approaching motion of the workpiece carrier 4 is stopped. The positional data of the workpiece carrier 4 obtained by the control wire $ is now calculated from the known and stored reference disk 18 and the size data of the reference tracker 19. A desired switching point is obtained from the reference tracker 19 and the sized data and the X-position data at which the reference tracker 19 will be actuated. The actual switching point usually deviates from it. Save the itinerary. Then, as shown in Fig. 3, the control device assigned to the A-axis is commanded via the A control wire 9, so that the reference tracker 19 is extended in the Y direction by its tracking pin 2丨. Tracking of the reference disk 18 in the x-direction is then performed by triggering the pair of drive devices assigned to the X direction via the control wire 8. This value is also determined by this test, which is based on the following figures in Figure 2 -12·1339147. In the month, the result of the test is relatively able to determine the position of the rotation axis D of the pin 21 in the reference tracking ". Now proceed to the uranium that is perpendicular to the plane in Figure 4, and you can use it in Figure 4 to trace the wealth. Via the Ζ (4) wire 6 wide. The drive device lacking h叩 causes the reference tracker 19 to ring the #1 value two 5 for the gamma direction test. The corresponding value Δχ Ay is thus obtained. Store them. After the first line of these tests, it is always done in the step of recalibration: the series of grinding tests. In Figures 6 to 12 to =, :! : Then try. According to Fig. 6'--the first grinding 22 corresponding to the χ direction: 丫 square: the cylindrical bristles clamped by two pieces 4 or the grinding wheel of the other body;: at XJ = supported by the grinding head 3 Now a short push in the X direction is entered into the direction of the other machine 15 and then the second body 22 is subjected to a second grinding test by the same-grinding wheel 23, wherein the workpiece carrier 4 is rotated around the longitudinal axis of the workpiece carrier 4 Hey. . A first facet 25 is now produced directly next to the facet 24 which has been ground for the first time and which is shown in FIG. In this case, the target of adjusting the data according to the existing machine is in the depth] but the New Zealand can not be directly obtained in the first measurement, = the correction value obtained in the upper examination Λχ (according to Figure 2 and Figure ^: ^ is not accurate Fig. 8 shows 'how the grinding wheel 23 actually passes through the tooth body 22 at different depths for the grinding test according to Figs. 6 and 7, so that there is almost no difference in the grinding depth - 13 - 20 1339147 % Year ο月 w日修 (more) is just for the purchase of 24' 25 has a significantly different size. Now the difference in the size of the facet 24'25 can be inferred a necessary correction of the correction value Δχ. In the simplest case This can be done by the operator and input to the control device 7 via the input device. However, it is also possible to measure only the dimensional difference of the facets 24, 25, ie the difference in length in the circumferential direction of the body 22 and to input this size into Control device 7. In this case, the control device 7 can correct the value 通过 by a quantity correction, which is proportional to the size difference of the facet 24' 25. After repeating this correction, repeat the operation according to Fig. 6 and 7 grind checksum sum The test of the facet 24' 25 with which it is engaged and the G positive of the correction value Δχ are the same size until the facet 24'25. If this is done, it is considered to add the correction value repeatedly determined in the grinding test to the correction value. The additional correction value AxR of Δχ is used as the correction value of the reference tracker and is used accordingly for the remaining coordinate directions Y and Z. This correction value is identical at least in the deflection direction of the reference tracker 19 in all of its detection pins 21 perpendicular thereto. Switching point position. The grinding test shown in Figures 6 to 9 is used to referencing according to the tracking procedure of Figures 3 to 5, while Figure 12 shows a grinding test procedure. It is used to calibrate the reference tracker 19 during its tracking process according to Fig. 2. The test workpiece 22 is still used or other corresponding test workpieces can be used and this time it is ground on its end face.

This error represents a deviation ΔXA from the axial direction of the reference tracker 19. The decision value ΔχΑ is completed when the parameters of the facets 26, 27 obtained in the iterative grinding test are the same. 10 The first recalibration of the grinder 1 must be performed after the calibration of the machine 1 and the reference tracker 19 thus achieved, wherein the machine tracker 14 is calibrated. This process is illustrated in Figures 13-16. The recalibration is carried out by tracking the test work 16 with the machine tracker 14 or its tracker component 15, which is for example designed as a cube. To this end, the test workpiece 16 is probed twice in the X direction according to Figs. 3 and 4, wherein the test workpiece is at 90 during two probe inspections. Rotate around the x-axis. The now-obtained switching position is stored immediately after the initial calibration by the reference tracker 19 and is used as a given value at which the touch-tracking benefit 14 is a response. The test workpiece 15 is accordingly tracked in the γ 15 direction according to Fig. 15 and in the Z direction according to Fig. 16, wherein the obtained switching position is still stored as a set value. This is the calibration of Yuan Wang Yuancheng grinder. The operation can be incorporated on the basis of the existing correction values Ax, Δy, AxR, ΔχΑ. If recalibration is required after a certain period of time, for example because the grinder produces a temperature change, repeat the recalibration according to item 13纟16. If the deviation from the material stored in the initial calibration is generated during the detection of the four specimens, then (4) and the deviation from the stored value is stored for the future positioning of the grinding head 3 and the one-piece carrier 4 The recalibration described in the recalibration can be repeated frequently and arbitrarily every time and again by the •15-20 1339147 machine. °.
