NUMERICAL CONTROLLER FOR WIRE ELECTRICAL DISCHARGE MACHINE ADAPTED FOR CORNER CONTROL OF MINUTE BLOCKS

摘要

A numerical controller for controlling a wire electrical discharge machine generates section data such that a machining path commanded by a machining program is divided into sections with a sufficient distance, generates data such that the individual sections are re-approximated to a straight line or a circular arc based on the generated section data, and adjusts an operation of the wire electrical discharge machine at a corner portion and a circular-arc portion of the machining path, based on the re-approximation section data.
