Two commonly used programming methods in CNC machining centers
 CNC machining
1 Simple contour - The contour consisting of straight lines and arcs is programmed directly with the G code of the CNC system.
 
2 complex contour - 3D surface contour, in the computer with automatic programming software (CAD / CAM) to draw three-dimensional graphics, according to the surface type set a variety of appropriate parameters, automatically generate NC machining program.
 
The above two programming methods can basically meet the requirements of CNC machining.
 CNC machining
But it is very difficult to process the function equation curve contour, because the early milling CNC system does not have the function calculation function, and the processing program of the function equation curve can not be programmed directly by the G code, and the (lower version) CAD/CAM software usually does not Has the ability to input graphics directly from equations.
 
Therefore, the cutting function equation curve contour, usually using the method: according to the requirements of the drawings, calculate the coordinates of the points on the curve, and then use the straight line or arc command code programming procedures based on the calculated coordinate values, manual input system for processing.
