In the development chain of humanoid robots, lightweight is an eternal theme. In order to reduce the burden on the motor and leave space for the range, engineers are eager to hollow out every aluminium alloy structural part. As a result, ultra-thin-walled parts with a wall thickness of 0.5mm-1.0mm have become the norm.

The present invention relates to the field of residual stress machining deformation control technology, and in particular to a method for controlling workpiece deformation during machining. Background: Machining deformation is primarily caused by four factors: the initial residual stresses in the blank, clamping forces, cutting forces, and cutting heat, as well as residual stresses induced by the machining process.
