How to control precision in precision machining

It means that the relevant parameters after the parts are processed can be as close as possible to the ideal parameters. If the error is smaller, the accuracy will be higher. Generally speaking, the error will be controlled within a reasonable range.


If it is dimensional accuracy control, then it is recommended to use the trial cutting method to achieve the effect of control accuracy. However, this method is only suitable for controlling the accuracy in the single-piece production process, and the adjustment method is to control the accuracy before production. The position of the tool and the workpiece is adjusted to ensure that the machining process remains unchanged when the parts are mass produced, so as to achieve the effect and purpose of mass production.





If it is to control the accuracy of the shape, it needs to be completed by the accuracy of the machine tool and the tool. The common control methods mainly include the tool method, the generative method, and the tool tip trajectory method.





If it is to control the position accuracy, then it is necessary to ensure the accuracy of the position of the processed parts through machine tools, furniture and workpiece clamping, etc.
