Different CNC woodworking milling machine configuration on the different CNC system, its function is not the same. General CNC woodworking milling machines have the following general functions:
(1) point control function. This function allows the CNC milling machine to perform only point-controlled drilling.
(2) continuous contour control function. CNC milling machine through the implementation of linear and circular interpolation can be achieved on the tool path of the continuous contour control, processing of straight and arc composed of plane curve contour of the workpiece. The contours of non-circular curves can also be processed after straight and arc fitting.
