The machining accuracy is refers to the size related work has in the processing is completed. The actual geometry and the mutual position of the surface parameter value, degree of correspondence and pre design ideal geometry parameters on the demand. The machining accuracy usually include dimensional accuracy. The shape accuracy and position accuracy, content, range size precision machined surface with reference to limit the size error, the shape precision is used to limit the surface macro geometry error, position accuracy is used to limit the processing surface and reference the parallelism between each other. The verticality coaxial position error. Because of the performance of processing machinery. Technology and methods. Effects of different production conditions and other factors, the related parts processing machinery in its size. The shape and surface position parameters and the ideal parameters deviation error always exists, to represent the machining accuracy is usually used in the numerical size of the machining error. Mechanical components machining accuracy and surface quality of machining quality. Is the basis for mechanical product assembly quality, processing errors reflect the size of the processing precision.
