Abstract

A spherical measuring head of a probe in an on-machine measurement device is moved in one direction on a processed surface of a work. After the measuring head departs from one edge face of the work, the coordinate of the probe are detected when the moving speed of the probe in its axial direction reaches a predetermined speed that is set in advance. Then, the motion of the spherical measuring head on the processed surface of the work is conducted again in the reverse direction. Next, the coordinate of the middle point between the two edge faces are obtained from the above two detected coordinates, and the obtained coordinate of the middle point is set as the measurement reference position of the work.

201132450 VI. Description of the invention: [Technology of the invention; field] The shape of the 2:::===:=) is used to determine the position of the workpiece. Technology] On-board working hours, in order to achieve the shape accuracy of the material level, the r-needle is not self-contained. To this end, it is necessary to establish the relationship between the work of the workpiece and the work piece. In order to increase the relationship between the coordinates of the test piece, it is necessary to set the measurement method of the work piece to measure the position of the Ding machine as the slave method of measuring the position of the red scale. Since (4) the following (a) the amount of the work piece is known. Measure the reference center: For this purpose, -_ first place the centering powder in the rotation axis and then make the secret detection ϋ to center the center of the ball. The center coordinates. Weaving and dismantling the center coordinates of the above-mentioned guillotine wares = turn " ΐ 为 为 为 工作 工作 工作 工作 ί ί ί ί ί = = = = = = = = = = = = = = = = = = = = = = = In the shape of a cylinder, it is difficult to make the center of the four pieces == the center of the work piece coincide with the center of the work piece. This ^Niu's circle has a considerable set error with the melon clip, which is consumed by the operator's familiar 201132450. The technique does not have to make the work bulletin disclose that the following must exist in the shape of the coincidence, by the ten-shaped: if Tao Feng said the shape::: Because of the t?= force, the airborne measurement is performed on the shape of the workpiece of the workpiece, so the center of the roughing is added before the reinforcement. Therefore, in order to deal with the problem of the vertices obtained by the measurement, the vertices obtained by the processing G on the work piece make the center not-induced, and have been processed. In addition, the space for the evening is set, that is, in addition to the recent U-processing of the work piece, it is impossible to cope with the problem of the patent document or the south precision of the size. Or the work piece is opened. The patent document _ hiring ~ 2_4 publishes the 端面 疋, 端面 端面 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋Two techniques. The violent change of the displacement of the probe is used to measure the flaw, and the end face of the workpiece is detected in the special touch of the touch, because the contact head of the _ money needle is the material; the edge of the end face of the workpiece is surely detected. Therefore, the edge of the end face of the guard piece is estimated by the measurement of the second and the second. Therefore, the number of samples of the measured data is determined or determined. The vibration of the measuring device, the measured data, and the actual end === the shape of the end face of the dirt (d) are set in the reference position of the workpiece by the public door τ feminine test in Japanese Patent Laid-Open Publication No. 2008-200798. The functional machine tool will have a line-symmetric working piece with the machined surface and the orthogonal line. The machine tool is arranged to support the movable shaft of the movable shaft by the fluid bearing, and the two sides of the mechanical coordinate system are parallel. And, along the first and second parallel to the two lines, the measuring ball of the stylus tip of the probe is contacted from the working side, and the positional difference 4 201132450 which is increased by the contact is measured. In the technique of performing the positional deviation =, the setting of the control position deviation value in the digital health device is imaginary. According to the arrangement of the processing operation, in the case of each change, if there is a setting error, the number of surnames = direct new 仃 3 疋. In this resetting operation, the worst case is detected. The force of the collision, it is possible that the guide axis is held, and the 'probe and the guarding piece are used to measure the slight positional deviation. In this technique, the limit i is a straight line! Contact misdetection leads to The danger of fluid bearing coupling is disclosed in the original Japanese and Japanese Patent Application No. ^_51, which is easy to handle without cost. = The system is used for the rotation ==: Appearance J II. In the technique disclosed in the patent document, the surface of the inspection surface is unilaterally attached to the workpiece. The side surface is mounted on a jig or the like. When it is necessary to detect the surface of the installation, it is necessary to rotate the spindle or the workpiece by 18 〇 a : This posture is very difficult. Even if the spindle rotation degree is 4, it is very difficult to level. Therefore, there is no movement with the moving shaft. [Invention, the object of the present invention is to provide a solution for the shape of the solvable 201132450 tool == two riding point setting function and: ===$^3 line The symmetrical input has a measurement from the machine, and the variable axis is controlled by a plurality of movable axes. Further, the numerical control device is provided with an internal movement of the on-machine measuring device due to the fluid bearing. And the machine tool output position detection signal. And the 4-value machine has the position of each movable shaft and is configured to drive the movable shaft, and the device comprises: a _ drive control machine; respectively, facing each end line 2, from the working surface position detecting mechanism of the working piece The position detection of the output:: two, according to the mechanism calculated by the moving speed decoration speed calculation mechanism, the movement speed has reached the mechanism 'the position of each movable axis detected by the determination detection mechanism 'According to the storage of the σ stored by the storage mechanism for storage, and setting the machine center to transfer the axis of the work piece to detect the position of the drive device, the motor signal from the movable connection is input to the numerical control device; The location of the position inspection structure j has a reference to the mobile measurement device from the movable numerical control device. The position detection signal of the position of the upper measuring device is substantially different from the phase of the machine. The position detection signal outputted by the two phases is respectively composed of a bit A/D conversion device and a sine wave analog signal. The interface includes: a shock, (4) (four) is a digital bit; and an interpolated split, and the output digital signal is output by the divided digital signal of the sine wave analog letter 201132450. This is the detection device. This storage face ί laser interferometer is one of the detection devices. When the speed is interrupted, the moving speed has reached the pre-determined position. The automatic moving shaft position detecting mechanism detects the mechanism of the Ke moving shaft. The horizontal and the opposite ends of the processing surface are stored by the storage target. The center of the water-paying direction can be == ί直二=; the standard is the work = 纽二^' to set it as the reference point for the work piece. The structure of the fixed function can be provided with a measuring reference point setting on the machine, a setting of the type of the probe supported by the fluid bearing, and a measuring reference point of the workpiece. [Embodiment] An example of an on-board measuring device provided in a machine tool of the invention. Figure 11. The important part of the section. The on-board measuring device 1 is omitted from the housing 1a. The probe body 1b is moved by the bearing Ϊ ##2 in the direction of the central axis of the probe body lb. As the bearing 2, a fluid bearing such as an air bearing can be used. There is a ruler id installed on the arrow ΐ 针 pin i=b. From the laser head 1c, the wire receiving member shown in the ruler 1d receives the displacement displacement from the axial direction of the ruler ^reflected light' One end of the stylus is equipped with a stylus le including a spherical measuring head 1f. m series, long rod-shaped members. Further, one end of the stylus le is fixed to the probe pin 1h to mount the spherical measuring head 1f. To simplify the description, the probe body lb, the stylus le, and the spherical measuring head lf will be collectively referred to as a probe pr in the future. 201132450 The ball type measuring work surface of the probe Pr is as follows: along the processing surface, according to the large fW of the magnet 1 and the spring in the device 1 of the touch device f, the built-in movement of the machine is used. , iH: 1, the value. The probe 忏 can be moved along the restriction mechanism shown in Fig. 1 (not shown). In addition, the range of the movable displacement of the ball type pin Pr can be set by the on-board measurement. It is necessary to worry about the processing surface Wa of the probe PU probe leaving the working piece W, and FIG. 2 also shows the age of the processing surface Wa surface of the second measuring device on the leaving machine. The head If is opposite to the working piece (right end lang and left end LE) as the opposite ends RL of the processing surface Wa of the workpiece W. Here, the workpiece w is separated from the workpiece w (the processing line of the road line and the path front. The symbol AP is a system! The rough processing surface or the end surface position of the processing surface workpiece f of the trimming work piece w Let the probe pr be referred to as "close to position AP" by the probe Pr shown in FIG. Mingben = the machine on the machine to measure the action of the probe in the work area Wa, said that the first, the force from the work piece, the action on the public.

Move the probe P" to move the target (the path is set to the right side of Figure 2, and then return to the work piece w again, leaving the right end position of the workpiece W, the position close to the processing surface, AP, and then from the workpiece). It moves until it moves away from the workpiece (the path probe Pr is opposite to the machined face of the workpiece W, =LE: so, by making the positions of the two ends (RE and LE). Relative movement, to detect the work Piece w

Next, the principle of the present invention of the end face position of Fig. 9 will be explained in more detail using Fig. 3. ^ ^ 2 The function of the ball type measuring head lf of the work piece W of the middle job is the symbol in the figure 3 of the work piece. The force of the T-system probe Pr V〇-based probe Pr leaving the working surface Wa, that is, the contact pressure. The initial velocity of the probe Pr axis when the V-system probe pr is from the working member w ° Wa. Degree, the mass of the probe Pr, and the acceleration of the probe Pr axis after opening. Since the processing surface Wa of the workpiece W is separated from the ball-shaped measuring head of the eucalyptus needle Pr, the working speed of the processing surface Wa along the workpiece W when the end surface of the processing surface 脱离 is removed from the work 8 201132450. ~time. V denotes the probe pr, and the flow bearing support such as the bearing provided in the on-board measuring device i is pressed by the processing of the air working member W from Wa by the turning body lb'. The contact pressure is applied to the probe body lb by an external force.推The above-mentioned magnetic force pushing mechanism is the influence of the force from the surface of the paper surface to the side. In addition, the contact system is not fixed. The movement of the needle is not in the state, because the ball type is measured in the head lf state, so the ball type measuring head lf is self-page; the force of the processing surface of the workpiece W - τ. In addition, in the processing surface of the workpiece, the object of the T is reversed. ====================================================================================== The quality of the acceleration is represented by α = Μχα. Moreover, the motion equation of the probe Pr can be moved. Further, the machined surface w p of the workpiece W is moved in the movable range of the measurement measuring unit i 15 so that the spherical measuring head 1 f of the probe pr becomes zero immediately. &, the force of the self-pushing mechanism on the probe is not the same as the speed i of the workpiece w, and the ball type measuring head is self-working ball type measuring head for the surface part = the needle and the axial direction of the needle The initial velocity is the same, then the speed of the probe Pr changes after the processing of the workpiece w/W is added. The motion track without Pr is the same regardless of the position of the end face. In addition, the probe is the same. The trajectory. Software? The position of either end face of the machined surface Wa is changed to 201132450. In the motion track and speed of the probe Pr

If the guard surface J of the work piece W is left, the spherical measuring head of the probe Pr is easier to understand by observing FIG. 4A and FIG. 4B. ', the situation of the time. Further, the position of the end face of the workpiece W is measured with reference to Fig. 3, but due to the spherical surface. If If is a ball type', therefore, the ball type measuring head if most of the time does not leave the end» itf is placed on the probe axis (= face) of the probe Pr, so it is caused by the roughing of the processing surface or 2 plus ^^零), the small speed change is the path of the movement of the pin and the shape of the force and the 2g, pr ^ but because the ball type measurement head lf is the ball to leave the work piece to know the surface, the shape moves, the speed _ Face), so it is impossible to follow the part, so the speed change is irregular. The side (four) points are measured on the non-machined surface. The abruptly placed ball is completely removed from the workpiece W. Since the day, I’m going to leave ε,

Wa (quantity,): two; ringing by the fluid bearing support because the probe body of the needle pin, such as from the moment ΐ ϊ Γ Γ Γ rubbing force does not act on the probe body 1b. Therefore, the change is linear (except that the 艏1^^^^^ is based on the contact τ (the ejection force) and its velocity W is determined to leave). The ball type measuring head If is represented by Va as described using Fig. 3; /4β^. Regarding the change in the axial velocity of the probe Pr, the capture of the probe Pr, i', depends on the acceleration of gravity and the angle of inclination when the contact pressure T is adjusted by the inclination of the needle. The latter is called the same as the contact shot, because the end position (position ρι) 10 201132450 and the detected coordinate (position P4) of the workpiece f are correct to the end position. ^—The end faces are all constant, so you can find them. Based on this, it can be found that the center position of the correct working piece w is shown in Fig. 4A - Fig. 4C Φ, j» si _ when the end face inspection is shown in Fig. 4C, and the moving speed in the axial direction of the probe is The pressure τ is constant and there is no premise of gravity. The working piece is added by ^, the direction of Pr, so that the probe pin contacts the one shown in Fig. 2. At the position LE, the right end position RE of the gravity W is the same as the left end face, and this is also limited with the above-mentioned gravity-free shadow. For the case where the change between ίίτ _ is the same as the 'contact pressure τ is not necessarily'; = 2 two regardless of the red work of the 0-end secret, only m ... Pan said that B has the use of the above measurement principle...

The output measurement signal is synchronized and input to the servo control unit 8b of the numerical control device 8. In the embodiment of the present invention, the position detecting device or the detecting tool machine of the probe body of the measuring device on the detecting device is moved. The position detection of the position of the linear motion shaft enables the (10), such as the ruler and the laser interference, to be quickly and accurately detected. In addition, the encoder can be used in the position detecting device for detecting the position of the rotating shaft of the machine tool. The device 8 comprises: a storage mechanism for storing the position information of each of the eight tools and the measurement information from the on-board measuring device (the position and the U-shaped storage in the storage device) The information is sent to the external storage leaf to calculate the difference moving speed according to the position information stored in the numerical control device 8.

Then the 'feeding machine' (fourth part) _ does not connect the motor and replaces the motor (10) with the measuring device 1. And, via the interface with the amplifier connected to the servo control unit 8bF, The measurement signal ipf from the on-board measuring device 1 (instead of the position detection signal from the position detecting device 96 built in the servo motor 95) is input to the servo control portion .8bF.
