What are the common failures of cnc machining the reasons for overcutting?

CNC Machining Refers To Precision Machining Controlled By Computers, Which Is Mainly Used For Machining Various Precision Parts . What Are The Causes Of Common Failures In Ordinary CNC Machining? What Are The Causes Of Overcutting During Machining?

　　1. Causes Of Common Failures In CNC Machining

　　1. Overload. Causes: Excessive Cutting Volume, Frequent Forward Reverse Rotation, Spindle Motor Failure, Spindle Drive Installation Failure.

　　2. The Spindle Does Rotate. Reasons: The Spindle Drive Installation Fails, The CNC Installation Cannot Output The Speed Signal, The Spindle Motor Fails, The Spindle Drive Installation Fails, The Transmission Belt Is Broken.

　　3. The Spindle Speed Deviates The Command Value. Reasons: Motor Overload, Spindle Speed Command Output By The CNC System Has Problems, Speed Measurement Installation Failure Speed Response Signal Disconnection.

　　4. Abnormal Spindle Noise Vibration. Cause: Usually Occurs During Deceleration, There Is A Problem With The Spindle Drive Installation, Such As A Regeneration Circuit Failure In The AC Drive.

　　2. Reasons For Overcutting In CNC Machining

　　1. Overcutting In Arc Processing Of Machining Center . When CNC Machining Stops Internal Arc Processing, If The Selected Tool Radius RD Is Too Large Exceeds The Arc Radius R Required For Processing, Overcutting Is Likely To Occur. CNC Machining Programs Are Compiled Based On The Theoretical Summary Trajectory Of The Workpiece Without Considering The Movement Trajectory Of The Tool During The Actual Machining Process. Due To The Existence Of The Tool Radius, The Actual Trajectory Of The Tool Becomes Coarser Does Coincide With The Programmed Trajectory. In Order To Obtain The Correct Workpiece Surface Summary, The Tool Radius Compensation Instruction Needs To Be Used To Set The Tool Trajectory The Programmed Trajectory. Otherwise, Overcutting Of The Workpiece Is Inevitable.

　　2. Overcutting Judgment During Linear Machining. When CNC Machining A Workpiece Consisting Of Straight Line Segments, If The Tool Radius Is Too Large, Overcutting May Occur, Resulting In Workpiece Failure. This Can Be Judged By The Positive Negative Scalar Product Of The Correction Vector Corresponding To The Programming Vector.

　　Today's Explanation Ends Here. The Above Is All The Content For Today. I Believe That Everyone Has A Certain Understanding Of The Common Faults Of CNC Processing  The Reasons For Overcutting. Thank You Very Much For Your Patience In Reading.
