In the CNC machining center, today's programming methods are usually two kinds: 

① simple contour - straight line, arc composed of contours, directly with the CNC system G code programming.

②complex contour - three-dimensional surface profile, in the computer with automatic programming software (CAD / CAM) to draw three-dimensional graphics, according to the surface type set a variety of parameters, automatically generate CNC machining program. The above two programming methods can basically meet the requirements of CNC machining. However, it is difficult to process the function curve of the equation because the early milling machine numerical control system does not have the function function, and the processing program of the function equation curve can not be prepared directly with the G code. (The lower version) CAD / CAM software is usually not With the function directly from the equation input graphics. Therefore, the cutting function equation curve contour, usually used method is: according to the requirements of the drawings, calculate the coordinates of the points on the curve, and then calculated according to the coordinates of the line or arc command code preparation procedures, manual input system for processing.
