Why are WEDM workpieces prone to deformation?

If You Split A Bamboo In The Middle, Both Halves Will Bend, With The Larger Half Bending Less The Smaller Half Bending More. This Is Because The Material Itself Has Stress, The Splitting Process Breaks The Original Stress Balance Of The Material, Restores The Balance Through Deformation. The Same Is True For The Deformation Of Workpieces During Wire Cutting , The Cutting Process Breaks The Original Stress Balance Of The Workpiece. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience , With A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining.

The Deformation Size Of Wire Cutting Is Related To The Structure Of The Workpiece. Narrow Long Dies Punches Are Prone To Deformation, The Size Of The Deformation Is Related To The Complexity Of The Shape, Aspect Ratio, Etc.; Workpieces With Thin Walls Are Prone To Deformation.

If The Deformation Is Very Small Within The Precision Range Required By CNC Machining , This Deformation Can Be Almost Ignored. However, If The Deformation Exceeds The Machining Precision Requirements, It Will Cause Obvious Deviations In Size Affect The Machining Shape Of The Workpiece.

There Are Many Reasons For Wire Cutting Deformation, Such As Material Problems, Heat Treatment Problems, Structural Design Problems, Process Arrangement Problems, Workpiece Clamping Cutting Path Selection Problems During Wire Cutting, Etc. These Various Reasons Will Cause Deformation Due To Internal Stress Of The Material.

Precautions For Deformation Of Precision Parts During Machining

1) Rough Machining Stress Relief Cutting Before Cutting

2) Processing The Threading Hole

3) Optimize Processing Path

4) Multiple Cutting

5) Optimization Of Processing Technology For Multi-Hole Concave Templates

6) Set Multiple Retention Levels
