Abstract This article mainly tells of shaft parts process and design. Shaft parts is one of the frequently encountered typical parts in the machine, it is mainly used to support transmission parts, transmission torque and load bearing. Shaft parts is of revolving parts, and its length is larger than the diameter, generally by the concentric shaft within the outer cylinder, cone surface and hole and screw thread and the corresponding face.
This design is for a typical complex shaft parts, the parts of complex structural shapes, precision demand is higher, in order to guarantee the accuracy, must have a strict size requirement, and processing technology, the processing is difficult. This article tells the story of the parts processing process, process analysis, programming and cutting parameters selection, etc.
