During the CNC machining process of aluminum alloy materials, due to the large amount of removal, the product will be deformed due to stress release, cutting movement, clamping force and other factors during the cutting process of CNC tools. Aiming at the problem of stress, it is recommended to increase the release hole during the roughing process, so that the stress in the material can be released during the cutting process. The larger the diameter, the greater the impact rigidity of the cutting, resulting in a corresponding increase in the stress in the material. In addition, the selection of the tool path also needs to distribute the stress evenly. For example, the diagonal structure is processed first, so that the stress can offset each other. .

Cutting movement is also an important factor for deformation. On the premise of ensuring the clamping and positioning of the product, the choice of processing speed and feed will also affect the deformation. On the premise of ensuring the processing cycle, these two parameters and tool specifications should be adjusted. Verify or provide the best process parameters according to the experience of CAM programmers.

The main factors for the deformation of the aluminum alloy casing in CNC processing are the above two points. If it cannot be solved fundamentally, it is recommended to find the raw material aluminum extrusion manufacturer to verify different cooling methods, mainly to improve the internal stress of the material.
