Title: Displacement correcting method for machine tool
Inventor: KATO KENJI
IPC: B23Q15/18
Filed: 1991-06-24
Abstract: PURPOSE:To easily and properly correct a mechanical displacement occurring in an operation mode by producing previously the function of the mechanical displacement caused by the changes of the cutting process conditions and the time and correcting the displacement in the cutting process conditions. CONSTITUTION:A PC command producing part 10 outputs the data on the coolant using state (c) measured by a coolant measuring part 5, the lubricant flow rate measured by a lubricant flow rate measuring part 6, etc., to a correction value computing part 11. A real time clock part 12 which counts the present time T and a correction value storage part 14 which stores the arithmetic data are connected to the part 11. Then the part 11 discriminates the increase and the reduction of displacement based on plural types of state values that affect the displacement of a machine main body and applies these increase and reduction of displacement to the corresponding function in the discriminating conditions for acquisition of the correction value. Thus the mechanical displacement is properly corrected in an operation mode.
