Technical Theory of Precision Machining

At present, significant progress has been made in precision machining technology, and precision machining is no longer an independent machining method or a simple process problem, but has become a widely used systematic engineering. For the research of precision manufacturing technology, foreign countries should start earlier than China.

The extremely high precision of machinery can be divided into ordinary machining and precision machining. Precision machining is a machining process that uses the strictly constrained relative motion between parts and blades on precision machine tools to finely cut various materials, in order to obtain high shape accuracy and surface accuracy. At present, the academic community generally believes that the machining accuracy is 0.01mm
