The difference between CNC machining of precision castings and traditional machining

The difference between CNC machining of precision castings and traditional machining

CNC machining of precision castings is an important component of modern manufacturing, which differs significantly from traditional machining processes. Traditional machining generally involves processing from measurement to further processing, with a certain degree of arbitrariness in the machining process, which is closely related to the experience of personnel. Numerical control machining is the process of using computers to control cutting tools for precise cutting movements, which is entirely based on complex numerical operations and can achieve reasonable and complete process planning that traditional machining cannot achieve. Today, precision casting manufacturer Tianyao Metal will talk to you about the characteristics of CNC machining technology compared to traditional machining processes.

1. CNC machining technology is more complex than ordinary mechanical machining technology

The CNC machining process should consider the processability of the processed parts, the positioning benchmark and clamping method of the processed parts, as well as the selection of cutting tools, the formulation of process routes, cutting methods, and process parameters, which can be simplified in conventional processes. Therefore, CNC machining technology is much more complex than ordinary machining technology and has many influencing factors. Therefore, it is necessary to comprehensively analyze and arrange the entire process of CNC programming, and then improve it as a whole. The same CNC machining task can have multiple CNC process plans, which can be arranged with the machining parts as the main thread or with the machining tools as the main thread. The diversification of CNC machining processes is a characteristic of CNC machining processes, which is a significant difference from traditional machining processes.

2. The design of CNC machining process should have strict organization

Due to the high degree of automation in CNC machining, the adaptive ability of CNC machining is relatively poor. Moreover, there are many factors that affect CNC machining, which are quite complex and require careful consideration of the entire process. CNC process design must have good organization, which means that the design process of CNC machining must be meticulous, rigorous, and error free.

3. The inheritance of CNC machining technology is good

Any CNC machining process that has been verified through debugging, verification, and trial cutting, and has been proven to be good in CNC machining practice, can be used as a template for subsequent machining of similar parts, which not only saves time but also ensures quality. As a template itself, it is also a process of continuous modification and improvement during invocation, which can achieve the effect of gradual standardization and serialization. Therefore, CNC technology has very good inheritance.

4. The CNC machining process must be verified in practice to guide production

Due to the high degree of automation in CNC machining, safety and quality are crucial. The CNC machining process must be validated before it can be used to guide production. In ordinary mechanical processing, the process documents written by the process engineer can be directly sent to the production line to guide production. Generally, the concept of CNC machining technology is a process method that uses CNC machining to process parts.
