In CNC aluminum machining, accidental deformation is a thorny problem, which seriously affects machining accuracy and finished product quality.

The reason is that on the one hand, there is residual stress in the blank, which comes from the superposition of stress caused by uneven deformation during quenching and extrusion of profiles, which is easy to deform the workpiece during processing. On the other hand, the processing stress can not be ignored, such as asymmetrical cutting, short process intervals, and poor workpiece rigidity will give rise to processing stress, which will cause deformation.

To avoid such problems, a multi-pronged approach can be taken. Tool selection, optimize spiral Angle, front Angle and other parameters, and control tool wear, reduce the impact on parts. The processing method should be appropriate, symmetrical processing, layering technology, pre-drilling milling, etc., to disperse stress and reduce the risk of deformation. Cutting parameters should be reasonable, cutting force and cutting heat should be controlled, and deformation caused by excessive external force and overheating should be prevented. For thin-walled aluminum parts and other easily deformed workpieces, the appropriate method is used to avoid wall deformation caused by clamping force. In short, mastering these points and applying them flexibly can effectively reduce the accidental deformation in CNC aluminum processing, ensure smooth processing and product quality standards.
