System for correcting tool deformation amount

Abstract

A system for correcting a tool deformation amount by which the amount of deformation of a tool is corrected for machining. A preprocessing arithmetic operation means reads a machining program and supplies machining conditions such as a cutting speed and the like necessary for the calculation of the tool deformation amount, to a tool deformation amount calculation means. The tool deformation amount calculation means reads tool deformation parameters such as the rigidity of the tool and the like from a memory, and calculates the tool deformation amount from these tool deformation parameters and machining conditions. Further, a tool correction means determines a tool correction amount and the tool deformation amount and tool correction amount are added to a movement command to determine an amount of movement, which is interpolated by an interpolation means to determine a tool path. This arrangement enables a more accurate machining.
