In order to improve the accuracy of the groove width and reduce the number of tool changes, the milling cutter with a diameter of 7 than the groove width can be used to mill the middle part of the groove first, and then use the tool radius compensation function to mill the two sides of the groove.

Ball end milling cutter, ring milling cutter, drum milling cutter, cone milling cutter and disc milling cutter are often used in machining solid curved surface or variable bevel profile.

When the machining allowance is small and the requirement of surface roughness is high, the face milling cutter with cubic boron nitride blade or ceramic insert blade can be selected for high-speed cutting.

According to the principle of NC machining, the overall consideration is made according to the requirements of workpiece processing drawings, the format specified by the CNC milling machine is used for editing, and the processing program input is carried out according to the action sequence. Thus, it is necessary to know the precision machining technology of CNC lathe while compiling the NC program.

  1. Determine the process flow. The processing technology of CNC milling machine is very similar to that of ordinary machine tool. Through analyzing the workpiece, specify the processing route, select the processing procedure, select the machine tool, fixture and cutter. Determine the equipment baseline position and cutting amount. The difference is that CNC machine tools need to program the operation process.
  2. Calculate the tool coordinate value. In order to facilitate the programming and calculation of tool path coordinates. The workpiece coordinate, part size and shape must be calculated before machining, so as to determine the whole machining path of the tool.
  3. Write processing program, for simple workpiece can be written manually, but for complex processing workpiece, automatic programming is needed.
  4. There are many ways to input programs into CNC system, which are mainly accomplished by the operation panel of CNC control system. In addition, the interface between computer and CNC system can be connected to input program by computer.
  5. Comprehensive inspection of procedures. Through the function of graph magic shadow display or NC milling machine equipment running without load, the machine tool running track is checked, and whether the tool movement meets the requirements of capping.
