What Is The Impact Of Improper Processing Of Cnc Parts?

The use of cnc processing equipment for processing has high efficiency and good quality, but if the process design is not handled properly, it will directly affect the output and even the quality. Today, the editor will share with you the technical problems:

1. The cnc processing process is too scattered

The reason for this problem lies in fear of complexity (referring to preparation time), simple programming, simplified operation and processing, easy adjustment of tool setting with one tool, and accustomed to ordinary processing. 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 processing 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 processing sequence is unreasonable

Some cnc processing operators consider some problems in preparation and often arrange the processing 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.

Use G00 (G26, G27, G29) fast positioning instructions with caution. G00 instruction brings great convenience to programming and use. However, if the setting and use are improper, it will often cause undesirable consequences such as overshoot when returning to zero due to excessive speed setting, loss of accuracy, and damage to the equipment guide rail surface. If the return route is not paid attention to, it is easy to cause safety accidents that collide with the workpiece and equipment. Therefore, when considering the use of the G00 command, it should be thoughtful and not arbitrary.

In the numerical control processing, 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 processing, the program must be tested (turn on the power amplifier) to confirm whether the processing route is consistent with the design route.

The above are some common problems and solutions of the editor when using cnc processing equipment. There may be other problems encountered in actual work, but as long as the CNC processing technicians and operators think about it, and earnestly master the knowledge and skills of CNC, CNC equipment can bring great benefits to the enterprise. .
