1. CNC processing process process is excessively dispersed
The root cause of this problem depends on the fear of complexity (referring to the time of preparation in advance). The program compiles simple and simplifies the actual operation processing, and the use of a knife processing is easy to regulate the general processing of knives and habits. In this way, product quality (shape tolerance) is not easy to ensure, and productivity cannot be fully exerted. Therefore, CNC processing process staff and operators should understand the professional knowledge of CNC machine tool processing in all aspects, and conduct more trials to grasp relevant professional knowledge, try to use the centralized process process to carry out processing. It is often used several times. Of course Show its advantages. After the processing process is concentrated, the processing time of the enterprise is improved. Everyone puts a zero -distance layout of the two machines and equipment to complete the actual operation of two machines and equipment. The high efficiency has been greatly improved, and the quality has also been made good guarantee.
2. CNC processing order is unscientific
Some CNC processing operators have fully considered some issues prepared in advance, and often distribute the processing order extremely unscientific. CNC machine tool processing is usually carried out in accordance with the standards of general mechanical equipment processing processing process. For example, it is rough and then fine (swords), first inside, and then effectively select the main parameters of drilling. In this way, the quality and effect can be improved.
The use of G00 (G26, G27, G29) is cautious and quickly and accurately positioned the G00 instructions to make a very convenient for program writing and application. However, if setting and error operations, it will often cause adverse effects such as over -rushing, decreased precision, and machine -applied rail dumping of machinery and equipment due to excessive rate settings. Do not pay attention to the return line, and it is easy to occur in safety production accidents that hit the workpiece and machines and equipment of impact products. Therefore, when considering the application G00 command, it should be thoughtful and not casually.
In the processing of CNC machine tools, especially in particular, special attention should be paid to strengthening the search and trial operation of the procedure process. After the program flow is key to the automatic control system, the operator should use the SCH key and ↑, ↓, ←, → → → move the uncertainty and clear search, and change the system from time to ensure the accuracy of the system. At the same time, before announcing procedures for processing processing, it is necessary to pass the program process trial transport (turn on the amplifier) to determine whether the processing line is consistent with the design scheme line.
