Dimensional instability due to Release of material’s internal stress

Common methods to solve the problem of instability in workpieces due to the release of internal stresses in metal material in the CNC machining process:

Pre-treat the material:

Before machining, pre-treating the material, such as annealing or stress relieving treatment, can reduce:

1. 1. The internal stresses of the material,
   2. The possibility of deformation after machining.

Select the right tool and cutting parameters:

Choosing the right tool and cutting parameters can reduce:

1. 1. The stress and heat impact on the workpiece,
   2. Deformation after machining.

Changing the cutting direction: 

1. 1. Refers to changing the direction of the tool relative to the workpiece surface during CNC machining.
   2. Considering the geometry of the workpiece to minimize deformation   During CNC machining cutting.

Regular inspection and adjustment:

Regularly inspecting the dimensions of the workpiece during machining and adjusting as needed can help to identify and solve deformation problems in a timely manner

Use support structures:

For workpieces that are prone to deformation, support structures can be used during machining to support the workpiece and reduce the impact of deformation.
