CNC machine tools are classified according to the movement mode

CNC machine tools are classified according to the movement mode

       1. Point-controlled CNC machine tools. The characteristic of point-controlled CNC machine tools is that the CNC system only controls the coordinate values ​​of the starting point and end point of the movement of the moving parts of the machine tool, but does not control the movement path of the moving parts. In order to reduce the movement and positioning time of the moving parts, the moving parts generally move to the vicinity of the end point coordinates at a fast speed, and then accurately move to the end point position at a low speed to ensure stable positioning accuracy.

      Since the point-controlled CNC machine tool starts processing after the tool or workpiece reaches the specified position, the tool does not cut during the movement.

CNC drilling machines, CNC coordinate boring machines, CNC punching machines, CNC spot welding machines, CNC pipe bending machines and CNC measuring machines all adopt the point position control method.

      2. The point-line control CNC machine tool and the point-line control CNC machine tool are characterized in that in addition to controlling the coordinate values ​​of the starting point and end point of the moving parts of the machine tool, it can also realize the cutting advance along a straight line or an oblique line between two points. Give movement; typical machine tools are CNC lathes, CNC milling machines and CNC boring machines.

     3. Contour control CNC machine tools have what is called continuous trajectory control. The feature of contour control CNC machine tool is that it can control two or more coordinate axes at the same time. Interpolate between multiple coordinate axes, coordinate axis linkage).
