Abstract
The invention discloses a magnetic die plate cavity machining method including a control system. A numerical control macroprogram of the control system converts the cutting depth and speed, and machining line spacing into cutting variables by taking the workpiece coordinate system during the machining as a reference on the basis of the data in the drawing, and by means of the numerical control macroprogram, a numerical control system can perform automatically point-getting calculation by increasing the cutting depth and the cutting speed. During the machining, the cutting depth and the machining line spacing of a cutter always follow the rotating speed of a main shaft to perform the reciprocating motion on the deep cavity of the workpiece to realize the machining, and the machining of the workpiece having a deep inner cavity and large balance can be realized through the synchronous control of the main shaft and the cutter. The method has the advantages of short machining time, high work efficiency, large cutting depth, high cutting speed, and less cutter wearing.
