The Principles of CNC Machining During the Production

– The Principles of CNC Machining Sequence

① The processing of the previous process cannot affect the positioning and clamping of the next process.

② It should carry out machining with the same installation method or with the same tool in succession to reduce the error caused by repositioning or tool change.

③ In the same installation, the process that has a relatively small impact on the rigidity of the work-piece should be carried out first to ensure that the work-piece is gradually processed under sufficient rigidity.

– The Principles of Determining CNC Machining Route

① Ensure the accuracy and surface roughness of the work-piece to be processed.

② The processing route is the shortest, reducing the idle stroke.

③ Simplify the numerical calculation workload as much as possible.

④ Make full use of command functions to simplify processing procedures.

– The Principles for Determining the Installation Method of CNC Machining Work-pieces

① Unified benchmark.

② The minimum number of clamping.

③ Minimum time occupied.

– The Principle of Determining CNC Machining Tools

① The tool has high rigidity and durability, which shortens the tool change time.

② The size of the tool is stable and the installation and adjustment are simple.

– The Principle of Determining CNC Machining Cutting Amount

① High production efficiency of rough machining, taking into account economy.

② Finish machining quality first, taking into account production efficiency.

③ Eliminate over-cutting and under-cutting.

④ Leave machining allowance for the next process.
