Possible errors during precision casting CNC machining process
In the field of precision parts machining, CNC machining is a method of controlling machine tool motion and machining process through computer digitization and information digitization. CNC parts processing is also an important indicator to measure a country's level of technological development, comprehensive national strength, and modernization of information technology. It is also a reflection of a country's strength. Today, precision casting manufacturer Tianyao Metal will talk to you about the possible errors that may occur during the machining process of CNC parts?
1、 The principle error of CNC part machining is caused by the use of approximate machining motion modes or approximate tool profiles. As long as the principle error is within the allowable range, this processing method is still feasible. Manufacturing errors, installation errors, and wear during machine tool use all directly affect the machining accuracy of CNC parts in workpieces. Among them, there are mainly the rotational motion of the machine tool spindle, the linear motion of the machine tool guide rail, and the error of the machine tool transmission chain.
2、 The manufacturing errors, installation errors, and wear of CNC machining tools can all affect the machining accuracy of the workpiece. During the cutting process of the tool, the cutting edge and cutting surface generate strong friction with the workpiece and chips, leading to tool wear. The fixture errors in CNC part machining include positioning errors, clamping errors, fixture installation errors, and tool setting errors. These errors are mainly related to the manufacturing and assembly accuracy of the fixture.
