With the development of China's high-end manufacturing industry, various industries on the CNC machining accuracy and quality requirements of parts are becoming more and more stringent, in the process of precision parts processing, CNC machining equipment and processing technology on the accuracy and quality of the workpiece has played a vital role, so we should carry out corresponding management and control of the CNC machining process, ensure the stability of CNC machining production, and analyze the impact of precision CNC machining technology on the machining accuracy of precision parts.

CNC precision machining

In the CNC precision machining process, we need to put forward strict requirements for the quality of raw materials and semi-finished products used in processing production. In the application of CNC machining technology, production and processing management, precision machinery and equipment selection under comprehensive consideration to ensure efficient and high-quality parts processing process, precision parts CNC machining quality can be guaranteed by the above process.

In the process of formulating CNC machining process routes, structural principles are generally followed: benchmark first, divide the processing process stages, and ensure the processing quality of precision parts and the reasonable selection of mechanical equipment.

The requirement of CNC precision machining accuracy is to control the machining error of the part within a certain range before CNC machining, and there are many factors that lead to machining error in the process of CNC precision parts machining.

Therefore, we mainly analyze the impact of precision machining technology on precision parts from the following aspects:

1. Comprehensive error of the process system

2. The principle error of the processing method

3. Geometric error and adjustment error of machine tool

3. Manufacturing errors of tools and fixtures

4. The clamping error of the workpiece and the error caused by the wear of the process system

5. Error caused by thermal deformation of process system

5. Error caused by residual stress of workpiece.

Therefore, in actual processing, scientific and reasonable processing techniques and methods can only be used within tolerances. Machining errors are reduced as much as possible, thereby improving accuracy and economic efficiency in the machining process.
