Numerical control with an insert function for an in / out cutting movement or with an insert function for a circular movement

摘要

Numerical controller, which is configured to control a machine tool according to a machining program, wherein the machine tool performs a turning operation in which a cutting tool is moved into contact with a rotating workpiece to bring the workpiece into a desired shape, wherein the numerical control Comprises: an in / out machining operation condition analysis unit configured to analyze in the machining program instructed operation conditions for a machining in / out movement in which a polygonal shape having three or more vertices through the path of a Cutting tool is formed; anda machining in / out inserting unit configured to insert into the turning operation the machining in / out movement which is analyzed based on the operating conditions analyzed by the machining in / out operating condition analysis unit wherein the machining in / out movement is effected in a plane defined by a direction of turning and a direction perpendicular thereto.
