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

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. 本发明提供种线切割放电加工机用数值控制装置。该控制线切割放电加工机的数值控制装置生成将加工程序指令的加工路径分割为具有足够距离的区间后的区间数据，根据该生成的区间数据生成将各个区间再近似为直线或圆弧后的数据，并且根据该再近似后的数据来调整线切割放电加工机在加工路径的角部以及圆弧部的动作。
