Embodiment Construction

[0028] The invention realizes the space reversible interpolation of electric discharge forming processing through the three-dimensional conical reversible interpolation technology. The three-dimensional conical interpolation method for EDM processing of the present invention comprises the following implementation steps:

[0029] 1. The controller sends a pulse command to make the spindle respond quickly and move to the specified position at a certain speed.

[0030] Such as figure 1 As shown, the controller, the driver and the linear motor are connected in sequence, the linear motor is fixedly connected to the main shaft, and the grating scale is fixed on the linear motor and connected to the controller. The controller can be realized by DSP, and the controller sends corresponding pulse instructions to make the moving parts of the system run according to the instructions. The upper controller sends the pulse command to the driver, and then the motor realizes quick response a...

Abstract

The invention discloses a processing method for a numerical control machine tool of an electric sparkle forming machine. When an X axis and a Y axis shake, a processing electrode of a Z axis feeds or rolls back with certain speed in the vertical direction to replace traditional interpolation, namely the Z axis firstly moves to the given circle center position, and then the X axis and the Y axis move along a horizontal track. Therefore, due to the three-dimensional shaking feeding or rolling back during processing, discharging of processing scraps can be facilitated, and processing accuracy is further improved.

Description

technical field [0001] The invention belongs to the field of numerical control manufacturing, and in particular relates to a processing method of an electric discharge forming numerical control machine tool. technical background [0002] With its unique processing principle and good and stable processing performance, EDM technology has become one of the important processing methods of modern manufacturing technology. Its unique three characteristics of "overcoming rigidity with softness, compactness and fineness, and realistic profiling" occupy an extremely important position in the manufacturing fields of difficult-to-process materials, complex profiles, fine surfaces, low-rigidity parts and molds. After more than half a century The development has been widely used in aerospace, instrumentation, automobiles, geology and other fields. [0003] The EDM process includes the rapid positioning of the workpiece electrode, the interpolation feed of the electrode and the rapid ret...
