Why Do Precision Parts Deform During Machining?

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, The Balance Is Restored Through Deformation. The Same Is True For The Deformation Of Precision Parts Processing Workpieces, The Processing Breaks The Original Stress Balance Of The Workpiece. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience , With A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Processing. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.


The Deformation Size Of Precision Parts Processing 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.; Thin-Walled Workpieces 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 The Deformation Of Precision Parts, Such As Material Problems, Heat Treatment Problems, Structural Design Problems, Process Arrangement Problems, The Clamping Cutting Path Selection Of Workpieces During Precision Parts Processing, 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 Processing

2) Processing The Threading Hole

3) Optimize Processing Path

4) Multiple Processing

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

6) Set Multiple Retention Levels
