The principle of CNC machining error

What are the principles of CNC machining error of mechanical parts? Let’s have a brief understanding:

1. Processing deviation

The reason deviation of CNC machining is due to the selection of the approximate machining activity method or the similar tool appearance. Because of the deviation in the machining principle, it is called the machining principle deviation. The reason deviation should be within the promise line.

1. Geometric deviation of machine tool

The manufacturing deviation, installation deviation and wear in use of machine tools directly affect the machining accuracy of the workpiece. Among them, it is mainly the spindle rotation, the linear movement of the guide rail and the deviation of the transmission chain of the machine tool.

1. Manufacturing deviation and wear of cutting tools

CNC machining tool manufacturing deviation, installation deviation and wear in use, all affect the machining accuracy of the workpiece. In the process of cutting, the cutting edge, cutting face, workpiece and chip have a sharp conflict, which makes the tool wear. When the tool wear reaches a certain value, the surface roughness of the workpiece increases, and the chip color and form change, and appear to be vibration. Tool wear will directly affect the cutting rate, machining quality and cost.

The above is the principle of CNC machining error of mechanical parts, hope to help you.
