Wiseman briefly analyses what are the factors that are easy to deform in the machining of machine parts?

During The Machining Process, Deformation Of Parts Is Inevitable, Serious Cases Will Lead To Scrapping. First Of All, We Must Consider It Carefully During The Design. We Must Only Consider The Strength Of The Parts, But Also Pay Attention To The Rigidity Of The Parts The Manufacturing, Assembly, Use, Disassembly, Repair Issues. During The Processing, A Series Of Process Measures Should Be Taken To Prevent Reduce Deformation. So What Are The Factors That Are Prone To Deformation In The Machining Of Mechanical Parts ? Then Let Huiwen Make A Brief Analysis. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has A Full Range Of Equipment, CNC Lathe/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

1.1 Internal Forces Cause Changes In Part Processing Accuracy

During Lathe Processing, The Centripetal Force Is Usually Used To Clamp The Parts With The Three-Jaw Four-Jaw Chuck Of The Lathe, Then The Mechanical Parts Are Processed. At The Same Time, In Order To Ensure That The Parts Do Loosen When Subjected To Force Reduce The Effect Of The Inner Radial Force, The Clamping Force Must Be Greater Than The Mechanical Cutting Force. The Clamping Force Increases With The Increase Of The Cutting Force Decreases With It. Only In This Way Can The Mechanical Parts Be Subjected To Stable Force During The Processing. However, After The Three-Jaw Four-Jaw Chuck Is Loosened, The Processed Mechanical Parts Will Be Far The Original Ones. Some Are Polygonal, Some Are Elliptical, There Are Large Deviations.

1.2 Deformation Problems Are Likely To Occur After Heat Treatment

For Thin-Sheet Mechanical Parts, Due To Their Large Long Diameter, They Are Prone To Straw Hat Bending After Heat Treatment. On The One Hand, There Will Be A Bulging Phenomenon In The Middle, The Plane Deviation Will Increase. On The Other Hand, Due To The Influence Of Various External Factors, The Parts Will Bend. These Deformation Problems Are Caused Only By The Change Of Internal Stress Of The Parts After Heat Treatment, But Also By The Lack Of Professional Knowledge Of The Operators Their Lack Of Understanding Of The Structural Stability Of The Parts, Which Increases The Probability Of Deformation Of The Parts.

1.3 Elastic Deformation Caused By External Force

There Are Several Main Reasons For The Elastic Deformation Of Parts During Machining. First, If The Internal Structure Of Some Parts Contains Thin Sheets, Higher Requirements Will Be Placed On The Operation Method. Otherwise, When The Operator Positions Clamps The Parts, It Cannot Correspond To The Design Of The Drawing, Which Easily Leads To Elastic Deformation. Second, The Unevenness Of The Lathe The Fixture Causes Uneven Force On Both Sides Of The Parts When They Are Fixed, Resulting In Translation Of The Side With Less Force During Cutting, Resulting In Deformation Of The Parts. Third, The Unreasonable Positioning Of The Parts During The Machining Process Reduces The Rigidity Of The Parts. Fourth, The Existence Of Cutting Force Is Also One Of The Reasons For The Elastic Deformation Of Parts. The Elastic Deformation Caused By These Different Reasons All Illustrate The Influence Of External Forces On The Machining Quality Of Mechanical Parts.

In Actual Parts Processing, There Are Many Factors That Cause Parts Deformation. In Order To Fundamentally Solve These Deformation Problems, Operators Need To Carefully Explore These Factors In Actual Work, Combine The Essence Of Work To Formulate Targeted Improvement Measures.
