• Calculate the CNC machining annual production program to determine the type of production.
• Analysis of parts drawings and product assembly drawings, and analysis the parts for CNC machining process.
• Choose a good blank material.
• Develop the CNC machining process routes.
• Determine the CNC machining processing allowance for each process, calculate the CNC machining process size and tolerances.
• Determine the CNC machine used in the process and tools, fixtures, measuring tools and aids.
• Determine the amount of CNC milling, CNC turning and working hours.
• Determine the CNC machining major technical requirements of the process and test methods.
• Fill in the CNC machining process files.

In the process of formulating the CNC machining process, it is often necessary to make adjustments to the contents that have been initially identified in order to enhance economic efficiency. In the implementation of CNC machining process procedures, there may be unforeseen circumstances, such as changes in production conditions, the introduction of new technologies, new processes, new materials, the application of advanced CNC machine, require the timely revision of the CNC machining process rules and improve.
