Splitting a bamboo in the middle will cause both halves of the bamboo to bend, with the majority bending less and the smaller half bending more. This is because the material itself will have stress, and the process of splitting breaks the equilibrium state of the material's original stress, restoring balance through deformation. The same principle applies to the deformation of workpieces in wire cutting processing, as the cutting process breaks the original stress balance state of the workpiece.

The deformation size of wire cutting processing is related to the structure of the workpiece. Narrow and elongated concave and convex molds are prone to deformation, and the magnitude of their deformation is related to the complexity of the shape, aspect ratio, and other factors; Thin walled workpieces are prone to deformation.

If the deformation is very small and within the precision range required for CNC machining, this deformation can be almost negligible. But if the deformation exceeds the machining accuracy requirements, it will cause significant dimensional deviations and affect the machining shape of the workpiece.

The causes of deformation in wire cutting processing are multifaceted, such as material issues, heat treatment issues, structural design issues, process arrangement issues, and issues with workpiece clamping and cutting path selection during wire cutting. These various reasons will lead to deformation caused by internal stress in the material.

Preventive measures for deformation in precision parts processing
1) Rough machining or stress relief cutting before cutting
2) Processing threading holes
3) Optimize processing path
4) Multiple cuts
5) Optimization of Multi hole Concave Template Processing Technology
6) Set multiple temporary retention periods
