Complete cnc programming example for machinists who work on a Wire EDM machine (Electrical Discharge Machining)
CNC Wire Cut Introduction
Wire EDM cutting, also known as electrical discharge machining, is a process that uses an electrically energized thin wire to slice through metal. Wire EDM cutting uses rapid, controlled, repetitive spark discharges from the wire to the workpiece, thereby eroding the metal away. The workpiece must be electrically conductive.
Wire EDM cutting can provide high dimensional accuracy for close fitting parts. The process can make sharp inside corners.
Wire EDM Programming Example
G92 X0. Y0. G01 Y1.25 (P1) G02 X.5 I.25 J0. (P2) G01 Y.75 (P3) G03 X1. I.25 J0. (P4) G01 Y1.25 (P5) G02 X1.5 I.25 J0. (P6) G01 Y0. (P7) X0. (P8) M02
G92 command is used to assign program zero. You will include the distances and directions from the program zero point to the wire start point in your G92 command.
