Numerical control device for machine tool and numerical control method for machine tool

Abstract

[Problem]To provide a numerical control apparatus of a machine tool and a numerical control method of a machine tool capable of increasing a conversion ratio of the case of converting an NC program into an electronic cam program and improving working efficiency by eliminating the need to cut off electronic cam data before and after an S code or an M code. [Means for Resolution]An apparatus comprising electronic cam control means, reference shaft operation control means for controlling an operation of a reference shaft in the case of executing the electronic cam control means, a data table for command processing execution configured so as to describe a command equivalent to an S code or an M code to be executed in correspondence with the reference shaft in order to execute a function equivalent to an S code or an M code in synchronization with the reference shaft operated by control through the reference shaft operation control means, and command table control means for performing command processing control based on the reference shaft and the data table for command processing execution.
