Classification according to the control track of CNC machine tool movement. (1) CNC machine tool controlled by point and position Point position control requires to control the moving parts to move from one point to another for accurate positioning. The requirements for the motion track between points are not strict. In the process of moving, there is no processing, and the motion between the coordinate axes is irrelevant. In order to achieve fast and accurate positioning, the movement of displacement between two points generally moves fast first. And then approaches the positioning point slowly to ensure the positioning accuracy. As shown below, which is the motion track controlled by the point position. point position control motion track The machine tools with point control function mainly include CNC drilling machine, CNC milling machine, CNC punch, etc. With the development of numerical control technology, there are few numerical control systems which are only us...
