1. Choose a reasonable cutting amount. The staff selects the cutting speed to be used based on the material, hardness, cutting state, material type, and cutting depth of the aluminum shell to be processed. These conditions are essential for effectively reducing machine wear and tear.

2. Choose the appropriate cutting tools. Generally speaking, when rough cutting, it is better to choose tools with high strength and durability, which can better meet the requirements of rough cutting.

3. Select appropriate fixtures. The parts should fully meet the needs of the machine to reduce unnecessary positioning errors and select specialized fixtures and clamping tools.

4. Determine a reasonable processing route. Try to shorten the machining path of the aluminum shell during CNC Machining and reduce machine wear as much as possible.
