Abstract
A control system for a processing machine such as an eroding machine operates to determine preferred withdrawal directions between a workpiece and a tool. In addition to the path movements necessary for the treatment process, the control system determines in advance at each point along the predetermined path a withdrawal direction oriented away from the surface being processed. This withdrawal direction runs essentially normal or perpendicular to the surface being processed on the workpiece. The amount of the desired separation between the tool and the workpiece along the withdrawal path is applied as an input to the control system in accordance with predetermined parameters of the treatment process.
