Abstract
A Method and machine tool for compensating a wear of an electrode that machines a workpiece. The method includes selecting a current pocket from plural pockets of the workpiece; updating a wear compensation to be applied to the electrode for the current pocket based on wear compensation of a previous pocket, where the previous pocket is adjacent to the current pocket; and applying the updated wear compensation to the electrode for machining the current pocket.
Claims11
A method for compensating a wear of an electrode, used in an electric discharge machine, that machines a workpiece with at least one pocket, wherein the pocket is an amount of metal to be removed from the workpiece during a pass of the machine, the method comprising:
- machining a first pocket from plural pockets;
- comparing a length of the electrode at the end of the first pocket to determine a volume of consumed material from the electrode;
- selecting a current pocket, adjacent to the first pocket, to be machined from plural pockets of the workpiece;
- updating a wear compensation to be applied to the electrode for the current pocket based on a wear compensation of a previous pocket;
- and
- applying the updated wear compensation to the electrode and machining the current pocket from the plural pockets:
- wherein the current pocket is a second adjacent pocket.
