Problems solved by technology

However, even if the setting environment (temperature, humidity, etc.) of the electric discharge machining device or the material of the workpiece is the same, the characteristics of each workpiece are different due to differences in the manufacturer of the workpiece, so the target machining speed or machining accuracy may not be achieved. question

Abstract

Standard machining conditions are registered in advance for each workpiece material and other factors in correspondence to machining speed and precision. The standard machining conditions are selected for execution of machining. The machining precision is measured to determine whether or not the measured machining precision and machining speed (machining time) fall within an allowable target range. If they are not within the range, the machining conditions are modified and machining is executed again. This procedure is repeated until the machining speed and precision fall within the allowable range, at which point the machining conditions are additionally registered and stored. The added machining conditions can be used in the next machining process.

Description

technical field [0001] The present invention relates to a machining condition setting method in an electric discharge machining device such as a wire electric discharge machine or an electric discharge forming machine, particularly in an electric discharge machining device that automatically sets machining conditions. Background technique [0002] In the wire electric discharge device or the electric discharge forming device, the processing of high-speed and high-precision dies and the like can be realized by increasing the processing speed, improving the processing accuracy, and the like. In order to perform high-speed and high-precision machining, the setting of machining conditions is extremely important. However, there are many parameters in the processing conditions, and considerable experience is required to set these parameters optimally, and only a limited number of experienced persons can set the processing conditions. [0003] Therefore, a technique is known in wh...
