Description

technical field [0001] The present invention relates to a wire electric discharge machine, and more particularly to a wire electric discharge machine capable of adjusting machining conditions according to the machining state of a machined object. Background technique [0002] When machining is performed by a wire electric discharge machine, machining is performed using machining conditions prepared according to the workpiece and the diameter of the metal wire (Japanese Patent Application Publication No. 05-021690, etc.). Usually, the processing speed and processing accuracy obtained under these processing conditions are determined as theoretical values, but in reality, due to the position of the workpiece placed on the table, the long-term changes of the machine, and the individual differences of the machine, etc., it is not always possible to obtain the determined value. processing speed and processing accuracy. This is considered to be due to the difference in machining e...
