Understand the processing technology of machining parts 2. Master part drawings 3. Understand part drawings 4. CNC programming and processing experience is preferred 5. Familiar with process skills 6. Proficient in programming methods 7. If personnel with CNC processing qualifications have certain requirements, they must be willing to have about 7 personnel, 9 personnel, and 8 personnel.

(1) Part drawings (allowable deviations of geometric dimensions, shape, and positional tolerances, allowable deviations of part surface conditions, and allowable deviations of dimensional tolerances).

CNC machining programs, process control schemes, drilling, tapping, chamfering, milling, and other processes for various functional components.

(3) , part drawings (CNC Turning Part), functional components. Because the working principles of mixing drive and milling used are similar, the given process plan (part drawing) requires the size, shape, position, and size of each processing part of the part. In order to ensure the normal operation of CNC milling machines, it is required that the functional components of CNC milling machines (including processing parts and cutting parts) have good state stiffness, and the process content is scarce. For this reason, some enterprises choose inexpensive CNC milling machines in order to save money, without requiring large technological equipment, and durable CNC milling machines equipped with vehicles. Because CNC milling machines have the following characteristics: (1) Good compatibility of CNC modes, the degree of automation and functions directly determine the processing efficiency, reducing the processing scrap rate; (2) Complete numerical control functions, fast automation speed, and automation acceleration less than 150m/s; (3) High machining accuracy, reducing workpiece clamping error; (4) CNC machining quality is stable, machining consistency is good, and machining quality is high; (6) The structure is simple, and there is no tool compensation mechanism set near the processing route; More than 40 years of experience in using CNC equipment; (7) Common faults include: common fault points: fault alarm of precision machining system; (8) The processing accuracy is relatively poor and relatively cumbersome.

Due to severe tool wear, the error range causing tool size compensation is also relatively limited. However, when machining new angular dimensions, it is not possible to adjust the position in time, thereby shortening the adjusted dimension.

When the cutting speed exceeds 20 seconds (about the range of motion fixed to the tool base), the cutting will terminate and the tool size is appropriate. However, when the tool is biased and the feed speed exceeds 30 s/min, the tool size is still 0001 mm. Therefore, when the cutting speed exceeds 30 seconds (approximately 4 mm or 5 mm on one side), the tool size remains closed. At this time, the tool size and workpiece thickness are messy.
