Disc management

During the orbiting phase, the PLC can insert online motion stops ‘’Insert motion stops‘’ function [FCT-C41 Insert stop command, section: Description] during the EDM process. When the orbit channel rotates freely, the surface quality on this “disc” can be detected and optimised.

This function enables execution of the down and orbit geometries using different “discs”. The PLC can control contour accuracy and achieve the required machining quality by inserting these discs into the geometry of the down channel.

For example, the specified velocity of the spark generator can be used as a guide to measure the machining quality attained.
