SYSTEM FOR CORRECTING QUANTITY OF DEFORMATION OF TOOL.

摘要

A system which performs a working while correcting the quantity of deformation of a tool. A means (12) for operating a pre-processing reads a working program (11) and sends working conditions necessary to calculate the quantity of deformation such as a cutting speed to a means (13) for calculating the quantity. The means (13) reads out from a memory (15) deformation parameters of the tool such as a rigidity of the tool and calculates the quantity from the deformation parameters and the working conditions. A means for correcting the tool calculates the quantity of correction of the tool. The quantity of movement of the tool is calculated by adding the deformation and correcting quantities of the tool to a tool moving command and the path of the tool is calculated by interpolating the quantity of movement with an interpolating means. Thereby, the working of high accuracy is possible.
