CNC precision mechanical parts machining 7 errors you know how much?

In Such An Era Of Contention Among Hundreds Of Schools Of Thought, Mozi Once Said: "Sweet Melons Have Bitter Stems, Nothing In The World Is Perfect." Although All Industries Are Prosperous, They All Have Their Shortcomings. Plums Are As White As Snow, Snow Does Have The Fragrance Of Plums. Just Like Everyone Has Their Strengths Weaknesses, No One Is Perfect. It Is The Right Thing To Learn Others' Strengths Make Up For One's Own Weaknesses.CNC Machining Cannot Escape The Fate Of Being Outside The Industry. Some Errors Will Occur During The Machining Process. The Main Errors Are The Following Seven:

1. Processing Principle Error

The Principle Error Of CNC Machining Is The Error Caused By The Selection Of An Approximate Machining Motion Method An Approximate Tool Summary. Because There Is An Error In The Machining Principle, It Is Called The Machining Principle Error. As Long As The Principle Error Is Within The Allowable Range, This Machining Method Is Still Feasible.

2. Geometric Error Of Machine Tools

The Manufacturing Error, Installation Error Wear Of Machine Tools Directly Affect The Machining Accuracy Of Workpieces, Mainly The Errors Of The Machine Tool Spindle Rotation, The Machine Tool Guide Rail Linear Motion The Machine Tool Transmission Chain.

3. Tool Manufacturing Error Wear

The Manufacturing Error, Installation Error Wear Of CNC Machining Tools Affect The Machining Accuracy Of The Workpiece. During The Cutting Process, The Cutting Edge, The Tool Face, The Workpiece The Chips Have Strong Friction, Causing The Tool To Wear. When The Tool Wear Reaches A Certain Value, The Surface Roughness Of The Workpiece Increases, The Color Shape Of The Chips Change, There Is Vibration. Tool Wear Will Directly Affect Cutting Productivity, Machining Quality Cost.

4. Fixture Error

The Fixture Errors In CNC Machining Include Positioning Error, Clamping Error, Fixture Installation Error Tool Setting Error, Etc. These Errors Are Mainly Related To The Manufacturing Installation Accuracy Of The Fixture.

CNC Machining Accuracy Cannot Be Perfect, As Long As The Error Is Controlled Within A Certain Range, It Is Insignificant. Tool Manufacturing Error Wear.

5. Positioning Error

Positioning Errors Mainly Include Datum Misalignment Errors Positioning Pair Inaccuracy Errors. When Processing A Workpiece On A Machine Tool, Several Geometric Elements On The Workpiece Must Be Selected As The Positioning Datum During Processing. If The Selected Positioning Datum Does Coincide With The Design Datum (The Datum Used To Determine A Certain Surface Size Position On The Part Drawing), A Datum Misalignment Error Will Occur. The Workpiece Positioning Surface The Fixture Positioning Element Together Constitute A Positioning Pair. The Large Position Change Of The Workpiece Caused By The Inaccurate Positioning Pair The Cooperation Gap Between The Positioning Pairs Is Called The Positioning Pair Inaccuracy Error. The Positioning Pair Inaccuracy Error Will Only Occur When The Adjustment Method Is Used For Processing, Will Occur In The Trial Cutting Method.

6. Adjustment Error

In Every Process Of Machining , The Process System Must Be Adjusted In One Way Another. Because The Adjustment Cannot Be Precise, Adjustment Errors Occur. In The Process System, The Relative Position Accuracy Of The Workpiece The Tool On The Machine Tool Is Guaranteed By Adjusting The Machine Tool, Tool, Fixture Workpiece. When The Original Accuracy Of The Machine Tool, Tool, Fixture Workpiece Blank Reaches The Process Requirements Without Considering The Dynamic Factors, The Adjustment Error Plays A Decisive Role In The Machining Error.

7. Measurement Error

When Measuring Parts During After Processing, The Measurement Accuracy Is Directly Affected By The Measurement Method, Measuring Tool Accuracy, Workpiece Subjective Objective Factors.

The Above Seven Machining Errors Can Be Avoided To A Certain Extent. Therefore, Operators Who Need To Perform Machining Can Conduct More Careful Inspections Verifications In All Aspects Of The Seven Machining Processes That Are Prone To Machining Errors Before Performing Machining Operations. This Can Better Reduce The Impact Of Machining Errors.
