In the processing process of CNC machining machine tools, the error itself is inevitable, and there is an inevitable error between the workpiece and CNC machine tools. This constant error is called the original error.
Therefore, in order to improve the processing accuracy of CNC machine tools, controlling the original error of CNC machine tools is one of the important countermeasures. The possibility of the original error is systematically analyzed, and corresponding improvement measures are formulated according to the cause and type of error type according to the cause and type of error type. During the processing process, the position accuracy and geometric accuracy of the digital control working machinery have an important impact on the processing accuracy of the parts. Through position control and geometric accuracy control, the effects of position errors and geometric errors on parts must be reduced. At the same time, for the deformation error generated during the processing process, the heat deformation of the process is used to control the heat deformation of the air -cooled, water cooling, etc., and reduce the impact of the processing accuracy caused by the thermal deformation error. At the same time, for position errors, a reasonable selection of tools suitable for parts material to avoid the deformation of the tool. At the same time, choose a reasonable fixture according to the embryo shape of the processing parts. If necessary, it must be dedicated to the shape size of the component. Essence
