CNC machining plant how to rationally machining tools? How many elements of cutting volume?

CNC Machining , Also Known As Numerical Control Machining , Refers To Machining Performed With Numerical Control Machining Tools. Because Numerical Control Machining Is Programmed Then Controlled By A Computer, CNC Machining Has The Advantages Of Stable Machining Quality, High Machining Accuracy, High Repeatability, The Ability To Process Complex Surfaces, High Machining Efficiency. In The Actual Machining Process, Human Factors Operating Experience Will Largely Affect The Final Machining Quality. Next, Let's Follow Huiwen Zhizao Technology To See Some Valuable Experiences Summarized By An Old Driver With Ten Years Of CNC Machining Experience...

1. How To Choose Machining Tools Reasonably? What Are The Major Factors Of Cutting Parameters? What Kind Of Tools Are There? How To Determine The Tool Speed, Cutting Speed, Cutting Width?

1. When Plane Milling, You Should Use Carbide End Mills End Mills That Do Need To Be Reground. In General Milling, Try To Use Two Passes. The First Pass Is Best To Use An End Mill For Rough Milling, Pass Continuously Along The Surface Of The Workpiece. The Width Of Each Pass Is Recommended To Be 60%-75% Of The Tool Diameter.

2. End Mills End Mills With Carbide Inserts Are Mainly Used For Processing Bosses, Grooves Box Surfaces. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience . It Has A Full Range Of Equipment, Including CNC Lathe/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

3. Ball Cutters Round Cutters (Also Called Round Nose Cutters) Are Often Used To Process Curved Surfaces Variable Angle Contours. Ball Cutters Are Mostly Used For Semi-Finishing Finishing. Round Cutters With Carbide Inserts Are Mostly Used For Roughing.

2. What Is The Function Of A Processing Procedure Sheet? What Should Be Included In A Processing Procedure Sheet?

1. The Machining Procedure Sheet Is One Of The Contents Of CNC Machining Process Design. It Is Also A Procedure That The Operator Needs To Follow Execute. It Is A Specific Description Of The Machining Procedure. The Purpose Is To Let The Operator Know The Content Of The Program, The Clamping Positioning Methods, The Tools Selected For Each Machining Procedure, The Issues That Should Be Paid Attention To.

2. The Processing Program Sheet Should Include: Drawing Programming File Names, Workpiece Name, Clamping Sketch, Program Name, Tool Used In Each Program, Maximum Cutting Depth, Processing Nature (Such As Rough Processing Fine Processing), Theoretical Processing Time, Etc.

3. How To Divide CNC Processing Procedures?

The Division Of CNC Machining Processes Can Generally Be Carried Out In The Following Ways:

1. The Centralized Tool Sequencing Method Is To Divide The Process According To The Tools Used, Use The Same Tool To Complete All The Parts That Can Be Completed On The Part. Then Use The Second Third Tools To Complete The Other Parts That They Can Complete. This Can Reduce The Number Of Tool Changes, Compress Idle Time, Reduce Unnecessary Positioning Errors.

2. For Parts With A Lot Of CNC Processing Content, The Processing Parts Can Be Divided Into Several Parts According To Their Structural Characteristics, Such As Inner Shape, Outer Shape, Curved Surface Plane. Generally, Planes Positioning Surfaces Are Processed First, Holes Are Processed Later; Simple Geometric Shapes Are Processed First, Then Complex Geometric Shapes; Parts With Lower Precision Are Processed First, Then Parts With Higher Precision Requirements.

3. For Parts That Are Prone To Deformation Due To Rough Machining, They Need To Be Calibrated Due To The Deformation That May Occur After Rough Machining. Therefore, Generally Speaking, The Processes For Rough Machining Fine Machining Must Be Separated. In Summary, When Dividing The Processes, It Is Necessary To Flexibly Grasp The Structure Processability Of The Parts, The Function Of The Machine Tool, The Amount Of CNC Machining Content Of The Parts, The Number Of Installations The Production Organization Status Of The Unit. It Is Also Recommended To Adopt The Principle Of Process Concentration The Principle Of Process Dispersion, Which Should Be Determined According To The Actual Situation, But It Must Be Reasonable.

4. What Principles Should Be Followed In Arranging The CNC Processing Sequence?

The Arrangement Of The Processing Sequence Should Be Based On The Structure Of The Parts, The Condition Of The Blank, The Need For Positioning Clamping. The Key Point Is That The Rigidity Of The Workpiece Is Destroyed. The Sequence Should Generally Be Carried Out According To The Following Principles:

1. The CNC Processing Of The Previous Process Cannot Affect The Positioning Clamping Of The Next Process, The General Machine Tool Processing Processes Interspersed In The Middle Must Also Be Considered Comprehensively.

2. Carry Out The Inner Shape Cavity Processing Process First, Then Carry Out The Outer Shape Processing Process.

3. It Is Best To Carry Out CNC Processing Processes With The Same Positioning, Clamping Method The Same Tool In Succession To Reduce The Number Of Repeated Positioning, Tool Changes Platen Movements.

4. When Multiple Processes Are Carried Out In The Same Installation, The Process That Causes The Least Damage To The Rigidity Of The Workpiece Should Be Arranged First.

5. What Aspects Should Be Paid Attention To When Determining The Workpiece Clamping Method?

The Following Three Points Should Be Noted When Determining The Positioning Reference Clamping Scheme:

1. Strive To Unify The Standards Of Design, Technology, Programming Calculation.

2. Reduce The Number Of Clamping Times As Much As Possible, Try To CNC Process All The Surfaces To Be Processed After One Positioning.

3. Avoid Using Manual Adjustment Solutions That Occupy The Machine. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Machining Experience. It Has A Full Range Of Equipment, Including CNC Lathe/Milling/Grinding/Drilling/Machining. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

4. The Fixture Should Be Open, Its Positioning Clamping Mechanism Should Affect The Tool Movement During CNC Processing (Such As Collision). When Encountering Such A Situation, You Can Use A Vise Add A Bottom Plate To Clamp It.

6. What Preparations Should Be Made Before CNC Programming?

After Determining The Processing Technology, Before Programming, You Need To Understand:

1. Workpiece Clamping Method;

2. The Size Of The Workpiece Blank - To Determine The Scope Of Processing Whether Multiple Clamping Is Required;

3. The Material Of The Workpiece-In Order To Choose The Tool To Be Used For Processing;

4. What Are The Tools In Stock? To Avoid Modifying The Program Due To The Lack Of Such Tools During Processing, If Such Tools Must Be Used, They Can Be Prepared In Advance.
