The influence of precision cnc machining technology on tolerance

With the development of the machinery manufacturing industry, the requirements for the precision and quality of cnc machining of parts are becoming more and more stringent. In the process of cnc machining of precision parts, cnc machining technology has a crucial impact on the precision and quality of workpieces.

Therefore, we should manage and control the cnc processing process accordingly to ensure the stability of cnc processing production. Then, the influence of precision cnc machining process on the machining accuracy of precision parts is analyzed.

In the process of precision cnc processing, we need to put forward strict requirements on the quality of raw materials and semi-finished products used in processing production. In the preparation of CNC processing technology, the management of production and processing, and the application of precision mechanical equipment, the quality of CNC processing of precision parts can be guaranteed by going up a flight of stairs.

In the process of formulating the CNC processing process route, the structural principle is generally followed: benchmark first, divide the processing stages, ensure the processing quality of precision parts and the reasonable selection of mechanical equipment.

The requirement of precision cnc machining accuracy is to control the machining error of parts within a certain range before cnc machining. In the process of precision cnc machining, there are many factors that lead to machining errors. Therefore, we mainly analyze the influence of precision machining technology on precision parts from the following aspects: comprehensive error of process system, principle error of processing method, geometric error and adjustment error of machine tool, manufacturing error of tool and fixture, clamping of workpiece Errors and errors caused by wear of the process system, errors caused by thermal deformation of the process system, and errors caused by residual stress of the workpiece.

Therefore, in actual processing, scientific and reasonable processing techniques and methods can only be used within the tolerance range. Reduce machining errors as much as possible, thereby improving the precision and economic benefits in the machining process.
