Problems solved by technology

However, this method can only return to the original processing path at the speed stipulated by the established processing program, but cannot automatically change the speed by the algorithm according to the technological means of electric machining, resulting in too long return time of the original path or return failure

Abstract

The invention provides a speed control device for backtrack of an electrode original path in electric machining process, and the speed control device comprises a single board computer, an actuator, a motor and an electrode which are connected in sequence. The actuator is connected with a numerical control system through data wires. In the electric machining process, the speed control device for backtrack of the electrode original path can carry out speed adjustment for backtrack of the electrode original path according to a processing technical algorithm, thereby improving backtrack efficiency of the electrode original path and the electric machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric machining, and in particular relates to a speed control device for retracting the original path of an electrode during electric machining. Background technique [0002] In the process of electric machining, due to factors such as material removal blockage of the processed plate and unreasonable processing parameter settings, processing stagnation occurs in uncertain program segments, resulting in the inability to continue processing. When this happens, the operator is required to suspend the automatic processing, use the method of retraction processing to return to the front of the unprocessed section along the original processing path, and then re-process. Because there may be problems such as program jump, cycle, subroutine call and radius compensation in the processing program, it is very difficult to realize the retreat processing according to the processing program. The existing CNC system ...
