The CNC milling machine
The CNC milling machine is an indispensable machine in the mechanical industry.
The CNC milling machine has continuous control function, which is a complex curve interpolation arc interpolation to milling the plane and surface of workpiece.
The CNC milling machine has the energy of tool radius compensation. If the workpiece profile is programmed directly, the actual profile will be larger than the tool radius value when machining the inner profile of the workpiece, and when the workpiece outline is machined, the actual profile will be reduced by another tool radius value, so as to process the outline that meets the requirements of the drawing. If the workpiece profile is programmed directly, the actual profile will be larger than the tool radius value. When machining the inner profile of the workpiece, and when the workpiece outline is machined, the actual profile will be reduced by another tool radius value. By using the method of tool radius compensation, the CNC system automatically calculates the tool center trajectory, which makes the tool center deviate from the workpiece profile and a tool radius value, thus machining the outline which meets the requirements of the drawing. The trimming machine can make use of the function of tool radius compensation to change the tool radius compensation, and can also compensate the tool wear and machining error, and realize the rough machining and finishing of the workpiece.
The NC milling machine has the function of tool length compensation, which can compensate the length deviation of the tool after changing the tool, and can also change the plane position of the cutting tool, so as to control the axial positioning accuracy of the tool.
