What errors will occur in CNC processing?

CNC processing uses computer digitization and information digitization technology to control the motion and processing process of the machine tool. The device is a high-speed, reliable, multi-functional, intelligent and open intelligent universal pneumatic CNC system. CNC processing is also an important indicator to measure a country's technological development level, comprehensive national strength, as well as the degree of modernization of information technology. Its role is immeasurable in high-tech industries such as aviation, biology, and medicine, and is a concentrated reflection of national strength. Therefore, improving the technical level is an important way to improve the comprehensive national strength and national status. Therefore, what errors will occur in CNC processing? Let's learn about it together below:

The principle error of CNC machining is mainly due to the use of an approximate machining motion mode or tool profile. Why is it called processing principle error? It is because there are errors in principle. This method is still feasible if the principle error does not exceed the allowable range. During use, manufacturing errors, installation errors and wear directly affect the machining accuracy of the workpiece. These errors include rotational motion of the machine tool spindle, linear motion of the machine guide rail and error of the machine tool transmission chain.

The manufacturing errors, installation errors and wear of CNC machining machine tools have a great impact on the machining accuracy of the workpiece. The cutting edge, cutting surface, and workpieces and chips produce strong friction during tool cutting, causing tool wear. After the tool wear reaches a certain value, the surface roughness value of the workpiece increases, the color and shape of the chips change, and it is accompanied by vibration. Tool wear during cutting directly affects cutting productivity, processing quality and cost. The main errors of CNC machining fixtures include positioning error, clamping error, fixture installation error and tool installation error. The error is mainly related to the machining and assembly accuracy of the fixture.

Positioning errors in CNC machining mainly include errors in error reference and manufacturing of error positioning pairs. When machining a workpiece, multiple geometric feature points on the workpiece should be selected as positioning references to determine the machining position. If the selected positioning reference is inconsistent with the design reference, an uncorrected error will occur. The positioning surface and the fixture positioning element form a positioning pair. During the processing process, due to the inaccurate processing of the positioning pair and the matching gap between the positioning pairs, the position of the workpiece changes greatly, which is the error of the positioning pair processing. When processing using the adjustment method, the manufacturing error of the positioning pair only occurs in the adjustment method, but does not occur during the trial cutting process.

The above description is the errors that may occur in CNC processing. I hope it can help you.
