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.

There are many factors that influence welding distortion; in summary, these can be categorised into three main areas: materials, structure and process. Whilst ensuring the structural load-bearing capacity is maintained, weld dimensions should be kept as small as possible to minimise the impact of welding heat input on the material’s properties.

Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).
