CNC machining four major errors

1, processing principle error
The principle error of cnc machining is due to the error caused by the approximate machining motion or the approximate tool contour. Because there is an error in the machining principle, it is called the machining principle error. This type of processing is still feasible as long as the principle error is within the allowable range.
2, the geometric error of the machine tool
Machine manufacturing manufacturing errors, installation errors, and wear during use directly affect the machining accuracy of the workpiece. Among them are the machine tool spindle rotary motion, the machine tool guide linear motion and the machine tool drive chain error.
3, the manufacturing error and wear of the tool
Manufacturing errors, mounting errors, and wear during machining of CNC-machined tools all affect the machining accuracy of the workpiece. During the cutting process, the cutting edge, the cutting surface and the workpiece and the chip generate strong friction, which causes the tool to wear. When the tool wear reaches a certain value, the surface roughness value of the workpiece increases, and the color and shape of the chip change, accompanied by vibration. Tool wear will directly affect cutting productivity, processing quality and cost.
4, fixture error
The fixture errors of CNC machining include positioning error, clamping error, fixture mounting error and tool setting error. These errors are primarily related to the manufacturing and assembly accuracy of the fixture.
CNC machining accuracy is not perfect, as long as the error is controlled within a certain range, it will be insignificant. Tool manufacturing error and wear
