Spark erosion machine and a simulator for a spark erosion machine.

摘要

Spark erosion machine which comprises the following:a machining tank (5), in which a workpiece (10) is arranged;a processing unit (2) having an electrode, in order to provide a spark erosion of the workpiece (10) to carry out;a power supply unit (3), which is a voltage between the electrode and the workpiece (10) is applied;an nc - unit (4), which the processing unit and the machining tank in accordance with a processing program for carrying out of the spark erosion of the workpiece (10) controls;an input unit (61), in order to provide a shape of the electrode, a shape of the workpiece, and a depth of which represents a depth up to which the workpiece (10) is to be machined;a simulator (62, 62a), which a working surface (32) is calculated, which is obtained by adding an overlap of a three-dimensional electrode shape and the three-dimensional shape of the workpiece (10) in a plane perpendicular to a downwardly directed z - axis is projected, the working surface (32) is moved in steps in successive machining depths (s) is obtained, to a predetermined machining depth (a3) is reached, andan output unit (63, 63a), which outputs a list of save, each of which the respective simulated machining depth (s) and the associated working surface (32) comprises.
