How to control CNC numerical control machining accuracy

CNC numerical control machining is a method of precision machining using computer digital control technology. During machining, the control system will automatically select the tool according to the program requirements, automatically change the tool speed and feed speed, etc., so as to complete the machining of the part. CNC numerical control machining accuracy can be controlled in the following ways: Machine tool accuracy test: Check the accuracy of the alignment and movement of the machine tool to ensure that the direction of the spindle, bracket, axis, etc. is accurate. The angle and bending of the axis must be accurate, and the linear axis should also be checked. Parts or product testing: In this mode, check the size and position of the part, including checking parameters such as positioning, surface finish and shape. Also check the dimensional and geometric tolerances according to the requirements or application. Process Monitoring: Check the process steps at each stage to avoid process-related errors that can lead to defective products or unnecessary manufacturing delays. The above methods are for reference only. It is recommended to consult a professional for more accurate information.
