TOOL ROTARY TYPE MACHINE TOOL HAVING ROUNDNESS COMPENSATION AND CONTROL FUNCTION, AND ITS ROUNDNESS COMPENSATION AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of improper roundness by reading a compensation value of a tool position per rotation angle of a main spindle corresponding to a selected tool from a roundness compensation data file memory and compensating a position of the tool per rotation angle of the main spindle by the compensation value. ;SOLUTION: A controller 1 executes a read process of a roundness compensation control program and reads roundness compensation data corresponding to tool number of a tool mounted on a face plate from a roundness compensation data file memory 26 into a RAM 25. Next, the controller 1 executes an operation process of the roundness compensation control program and calculates a tool slider position compensation value which is a tool position compensation value. The tool slider position compensation value is calculated by calculating a compensation coefficient and multiplying the compensation coefficient by a reference compensation value. This compensation coefficient is calculated based on a position of a tool slider and the number of revolution of a main spindle.;COPYRIGHT: (C)1999,JPO
