Machining accuracy is a standard for Metal Stamping Parts industry, which can be divided into rough machining and finish machining. What are the precision requirements for these two kinds of processing?
Finishing refers to the processing of parts to precise dimensional tolerances, using precision processing equipment and having special processing technology requirements. Rough machining refers to the process that ordinary machine tools rough or process to a free tolerance range without surface requirements. The details are as follows.
In the metal Stamping Parts industry, machining accuracy refers to the degree to which the actual values of the parameters including size, geometric shape and mutual position of each surface of the relevant workpiece after machining are in conformity with the requirements of the ideal geometric parameters that should be provided in advance. Machining accuracy usually includes dimensional accuracy, shape accuracy and position accuracy. Dimensional accuracy is used to limit the range of dimensional error between the machined surface and its reference, shape accuracy is used to limit the macro geometric error of the machined surface, and position accuracy is used to limit the parallelism, perpendicularity, coaxiality and other mutual position errors between the machined surface and its reference.
