Description of the invention: '· Technical field to which the invention belongs. The present invention relates to a numerically controlled machine tool, and more particularly to a tool offset compensation system and method for a numerically controlled machine tool. [Prior Art] A conventional CNC machine tool uses a single tool on a single spindle to work on the workpiece. The tool compensation is only compensated for the single-tool. With the rapid development of science and technology, CNC machine tools are moving towards high performance, high precision and high speed. Multi-spindle CNC machine tools have emerged. Mass production with multi-spindle CNC machines greatly increases productivity. However, the long-time machining makes the multiple tool wear of the multi-spindle CNC machine tool not wear--but the tool compensation system in the traditional CNC machine tool can not accurately compensate the wear of multiple tools one by one, thus affecting the multi-spindle numerical control The machining accuracy of the machine tool. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a CNC machine tool compensation system to improve the machining accuracy of a multi-spindle CNC machine tool. It is also necessary to provide a CNC machine tool compensation method to compensate for the wear of multiple tools on a multi-spindle CNC machine. A numerical control machine tool compensation system includes at least one spindle for mounting a tool, at least one compensation device corresponding to the at least one spindle, a control system, and a tool setting device connected to the control system, the compensation device includes An actuating component connected to the control system, a transmission component disposed on the actuating component, and an adjustment platform disposed on the component of the transmission 4 201026429, the contact zone is rotated, and the tool setting device is used for measuring: The length of the tool on the spindle and the measured tool length are transmitted to the control system. • The tool length value of the miscellaneous miscellaneous (4) and the length value of the tool are calculated to calculate the compensation value. The actuating element kingpiece further drives the movement of the transmission element, and the transmission assembly drives the adjustment platform to compensate for the wear of the tool. - A CNC machine tool compensation method, including the following steps: ❹ Tool setting measurement - the length of the tool on the CNC machine spindle, and the measured tool length is transmitted to a control system; the control system according to the receiving _ tool length value and Wei Lu a length value of the tool to calculate a compensation value, and controlling a movement of the compensation device according to the compensation value, the compensation device is for supporting a workpiece; and the compensation device moves a distance equal to the compensation value in the tool direction to complete Wear compensation for the tool. The above-mentioned numerical control machine tool compensation system and method use the control system to control a plurality of 〇 compensation devices to respectively compensate for the wear of a plurality of tools of the multi-spindle CNC machine tool, thereby improving the machining accuracy of the multi-spindle CNC machine tool. [Embodiment] Referring to FIG. 1, the CNC machine tool compensation system of the present invention is used to compensate for the wear of a plurality of tools 16 on a multi-spindle CNC machine tool 100. The preferred embodiment includes a machine provided with four spindles 12. The body 10, a working platform 20, four compensation devices 30 disposed on the work platform 20, a pair of tool sets 50, and a control system 6〇β, wherein the mother-tools 16 are disposed on a corresponding main shaft 12.

The adjustment platform % moves up and down the drive assembly 33 = the spool 36. The two spools 36 act as a leveling agent for the % of the platform. Wherein the actuation assembly 32 can be a feeding motor. ❹ ❹ In the present embodiment, the wear compensation of the blade 16 on a spindle U by only the compensation device 3〇 will be described as an example. Prior to machining the workpiece 4, the tool setting tool 50 pairs the tool 16 to measure the actual length L1' of the tool % and transmit the measurement results to the control system. The control system 6 比较 compares the length value L1 of the second pair with the length value L2 of the tool 16 recorded by the system to calculate a compensation value L=L2-L1, and replaces the length value L2 with the length value L1 to Updating the 77-length value recorded by the system, and then mixing the value L to control the operation of the actuating member 32, thereby driving the transmission member 33 to move, the transmission assembly % belt = the adjustment platform 35 is moved to complete the pair The wear of the tool 16 is compensated. For example, when the actual length L1 of the cutter 16 measured by the tool setting tool 50 is 4.999 cm, and the length value of the cutter 16 recorded by the system is L2=5.000 cm, the compensation value calculated by the system L=L2-Ll= 5.000 cm - 4.999 cm = 0.001 cm.
