When CNC Machine Tools Are Processing Precision Mechanical Parts In Batches , Special Attention Should Be Paid To The Processing Accuracy. What Issues Should We Pay Attention To In Order To Ensure The Accuracy During Batch Processing? Our Huiwen Intelligent Manufacturing Engineer Will Introduce It To You The Following Three Aspects:
1. Poor Machining Accuracy Of CNC Batch Parts
Generally, It Is Because The Feed Dynamics Between The Axes Are Adjusted Properly According To The Error During Installation Adjustment, The Transmission Chains Of The Axes Of The Machine Tool Have Changed Due To Wear Tear. It Can Be Solved By Re-Adjusting Modifying The Gap Compensation Amount. When The Dynamic Tracking Error Is Too Large An Alarm Is Triggered, You Can Check: Whether The Servo Motor Speed Is Too High. Whether The Position Detection Element Is In Good Condition. Whether The Position Feedback Cable Connector Is In Good Contact. Whether The Corresponding Analog Output Latch Gain Potentiometer Are In Good Condition. Whether The Corresponding Servo Drive Device Is Normal.
Second, The Overshoot During Machine Tool Movement Causes Machining Accuracy Factors . It May Be That The Acceleration Deceleration Time Is Too Short, The Speed Change Time Can Be Appropriately Extended. It May Also Be That The Connection Between The Servo Motor The Lead Screw Is Loose The Rigidity Is Too Poor, The Gain Of The Position Loop Can Be Appropriately Reduced.
3. Roundness Deviation When Two Axes Are Linked
(1) Axial Deformation Of The Circle
This Deformation May Be Caused By Improper Mechanical Adjustment, Poor Axis Positioning Accuracy, Improper Screw Clearance Compensation, Which Will Cause Roundness Errors When Passing Through Quadrants.
(2) Oblique Elliptic Error
At This Time, You Should First Check The Position Deviation Value Of Each Axis. If The Deviation Is Too Large, You Can Adjust The Position Loop Gain To Eliminate It. Then Check Whether The Interface Board Of The Rotary Transformer Induction Synchronizer Is Adjusted Properly, Then Check Whether The Gap Of The Mechanical Transmission Pair Is Too Large Whether The Gap Compensation Is Appropriate.
4. Complete The Processing Of Parts
After The First Trial Cutting Of Parts Is Completed, Batch Production Will Be Carried Out. However, The Qualification Of The First Piece Does Mean That The Whole Batch Of Parts Will Be Qualified. Because In The Processing Process, The Tool Will Wear Due To The Different Processing Materials. If The Processing Material Is Soft, The Tool Wears Less, If The Processing Material Is Hard, The Tool Wears Quickly. Therefore, In The Processing Process, It Is Necessary To Measure Inspect Frequently, Increase Decrease The Tool Compensation Value In Time To Ensure The Qualification Of Parts.
In Short, After Talking So Much To You, I Think The Basic Principles Of Processing Are: Rough Processing First, Remove The Excess Material Of The Workpiece, Then Fine Processing; Vibration Should Be Avoided During Processing; Thermal Denaturation Of The Workpiece During Processing Should Be Avoided. There Are Many Reasons For The Vibration, Which May Be Excessive Load; It May Be The Resonance Of The Machine Tool The Workpiece, It May Be The Insufficient Rigidity Of The Machine Tool, It May Be Caused By The Passivation Of The Tool. We Can Reduce The Vibration Through The Following Methods; Reduce The Lateral Feed Rate Processing Depth, Check Whether The Workpiece Is Clamped Securely, Increase The Tool Speed Reduce The Speed To Reduce Resonance, Check Whether It Is Necessary To Replace The Tool With A New One.
In Short, Mastering The Operation Skills Of CNC Machine Tools Is A Gradual Process Cannot Be Achieved Overnight. It Is Based On Mastering The Basic Operation Of Machine Tools, Basic Mechanical Processing Knowledge Basic Programming Knowledge. The Operation Skills Of CNC Machine Tools Are Static. It Requires The Operator To Give Full Play To The Organic Combination Of Imagination Hands-On Ability, Is Innovative Labor.
