Process Analysis for connecting shaft : parts diagram for parts diagram analysis and research is carried out on parts review process, such as checking the view design drawings, dimensions and technical requirements for any errors, omissions, especially compared to the structure of the process of poor parts, if possible, and designers to communicate or suggest modifications, by the designer to decide whether to make the necessary modifications and improvement.

① view of completeness and correctness of the analysis part of the part drawing shall comply with the requirements of national standards, the location is accurate, clear expression; relationship between geometric elements (points, lines, surfaces) between (such as tangent intersects parallel) should be accurate ; dimensions should be complete and clear.

② the analysis part of the technical requirements of Part technical requirements include dimensional accuracy, form accuracy, position accuracy, surface roughness and heat treatment table requirements, these requirements should be able to guarantee the performance of the parts use limit premise. Be part technical requirements analysis, as well as the possibility to achieve is to analyze the reasonableness of these technical requirements, focusing on analysis and technical requirements of precision surfaces and important parts of the process to develop a reasonable plan ready. By analyzing to determine the technical requirements are too strict, because of high accuracy and surface roughness is too small will make the process complicated process more difficult, adding unnecessary costs. 

③ dimensioning dimensioning method to analyze partial part drawings are scattered labeling method, focus and coordinate labeling labeling method. CNC machining of the parts on the parts diagram in size to ensure performance of the premise, should be taken in order to focus on the same basis as marked or labeled (ie, marked coordinate dimensions) of the way, so convenient CNC programming, but also conducive to the design basis, the origin of the programming process unified basis. 

④ analysis of parts and materials to meet the parts function under the premise of cheap materials should be used, the material should be selected based on domestic, Do not choose expensive and scarce materials. Structural analysis of the process of structural parts of the process 

⑤ part refers to the design of parts, in the premise to meet the performance requirements of the manufacturing feasibility and economics. Good structure makes the process of machining parts easy, cost savings, material savings; rather poor structure will make the process of processing difficulties, increased costs, waste materials, or even can not be processed. Through the course of the structural characteristics of parts, precision and complexity of the analysis, you can determine the required parts processing methods and types of CNC machine tools and specifications
