Problems caused by improper cnc precision machining process arrangement

The use of cnc precision machining equipment for machining has high efficiency and good quality, but if the process design is not arranged properly, its advantages cannot be well reflected. From the experience of some cnc machining plants, there are some problems as follows:

  • 1. The cnc machining process is too scattered
    The reason for this problem lies in fear of complexity (referring to preparation time), simple programming, simplified operation and machining process, easy adjustment of tool setting with one tool, and accustomed to ordinary machining. As a result, product quality (position tolerance) is not easy to guarantee, and production efficiency cannot be brought into full play. Therefore, CNC machining process personnel and operators should be fully familiar with CNC machining knowledge, try more to master relevant knowledge, and use process-intensive methods for machining as much as possible. If you use it several times, it will naturally reflect its advantages. After the use of process concentration, the unit machining time increases. We arrange the two equipment face to face, and realize that one person can operate the two equipment. The efficiency is greatly improved, and the quality is also well guaranteed.
  • 2. The cnc machining sequence is unreasonable
    Some cnc machining operators consider some problems in preparation and often arrange the machining process sequence extremely unreasonably. CNC machining is usually processed according to the requirements of the general machining process, such as first coarse and then fine (tool change), first in and out, reasonable selection of cutting parameters, etc., so that quality and efficiency can be improved.

In the numerical control machining, especially should pay attention to strengthen the program retrieval and trial operation. After the program is entered into the control system, the operator should use the SCH key and the ↑, ↓, ←, → movement keys to perform uncertain and definite searches, and modify the program if necessary to ensure the accuracy of the program. At the same time, before the formal execution of the program machining, the program must be tested (turn on the power amplifier) to confirm whether the machining process route is consistent with the design route.

In actual work, there may be other problems, but as long as the CNC machining engineering technicians and operators brainstorm and master the knowledge and skills of CNC, CNC equipment can bring great benefits to the enterprise.
