CNC Precision Machining Manufacturers On Precision Machining Technology Testing

The Advanced Manufacturing Technology Of CNC Precision Machining Manufacturers Is An Integrated Technology That Integrates Many Modern Advanced Technologies In The Manufacturing Industry. It Mainly Includes Two Major Fields: Precision, Ultra-Precision Machining Technology Manufacturing Automation. The Following Is A Brief Analysis By Huiwen Intelligent Manufacturing .

Cutting Process Of Precision Cutting:

In The Precision Cutting Process Of CNC Precision Machining Manufacturers , A Micro-Cutting Method Is Used, The Cutting Depth Is Small, The Cutting Function Is Mainly Borne By The Cutting Edge Arc Of The Tool. Whether Chips Can Be Cut The Processed Material Depends Mainly On The Force Of The Material Point At The Cutting Edge Arc Of The Tool.

In Order To Study The Micro-Cutting Process Understand The Various Phenomena In The Cutting Process, The Transition Cutting Process Is Analyzed First. CNC Precision Machining Manufacturers Take The Cutting Of Rotary Tools As An Example To Analyze The Contact Between The Tool Cutting Edge The Workpiece Surface The Deformation Of The Workpiece Material During The Transition Cutting Process. Taking Huiwen CNC Precision Machining As An Example, It Is The Cutting Process Of A Single-Edged Rotary Tool Milling Plane. The Dotted Line Represents The Movement Trajectory Of The Cutting Edge, The Solid Line Represents The Contour Of The Machined Surface. The Moment The Tool Cutting Edge Contacts The Workpiece, The Tool Slides A Certain Distance On The Workpiece, Only Elastic Deformation Occurs On The Workpiece Surface. After The Cutting Edge Is Removed, The Workpiece Surface Can Still Return To Its Original State. This Sliding Of The Cutting Edge On The Workpiece Surface Is Called Elastic Sliding.

As The Tool Continues To Rotate, The Amount Of Back Cutting Increases, Plastic Deformation Begins To Occur On The Workpiece Surface. In This Plastic Deformation Zone, After The Cutting Edge Slides Over The Workpiece Surface, Grooves Are Scratched On The Workpiece Surface, But No Material Is Actually Removed At This Time. This Sliding Of The Cutting Edge On The Workpiece Surface Is Called Plastic Sliding.

After Plastic Sliding, As The Back Cutting Amount Increases, Chips Are Generated On The Front Surface, The Cutting Process Begins. Due To The Elastic-Plastic Deformation On The Workpiece Surface, The Movement Trajectory Of The Cutting Edge Does Coincide With The Contour Line Formed By The Machined Surface. By Changing The Cutting Angle Of The Tool, The Maximum Interference Depth Between The Tool The Workpiece Can Be Changed In Turn, So That A Curve Can Be Obtained. When The Maximum Interference Depth Of The Cutting Edge Is Very Small, That Is, The Cutting Angle Is Very Small, It Is The Cutting State.

At This Time, The Tool Only Slides Over The Workpiece Surface, There Is No Trace Of Tool Cutting On The Workpiece Surface. The Entire Contact Length Between The Tool The Machined Surface Belongs To The Elastic Deformation Area.

When The Maximum Interference Depth Between The Tool The Workpiece Reaches A Certain Value, The Cutting State Is Formed. The First Section Of The Cutting Is The Elastic Sliding Area, Then Enters The Plastic Deformation Area. After The Cutting Edge Slides Over, Grooves Will Be Left In The Plastic Deformation Area, But No Chips Will Be Generated. Continue To Increase The Maximum Interference Depth Between The Tool The Upper Part, The Cutting State Will Be Formed. At The Beginning Of The Contact Between The Cutting Edge The Workpiece Surface, It Is The Elastic Sliding Area. As The Back Cutting Amount Increases, It Becomes The Plastic Sliding Area, Then The Cutting Area. The Grooves On The Workpiece Surface Are Formed By Plastic Deformation Chip Removal. As The Back Cutting Amount Decreases, It Then Transitions To The Plastic Deformation Area The Elastic Deformation Area.

CNC Precision Machining Manufacturers Must Point Out That There Is Also An Elastic Deformation Zone In The Plastic Sliding Zone, There Are Both Chip Removal Zones Plastic Deformation Zones Elastic Deformation Zones In The Cutting Zone.

Therefore, During The Micro-Cutting Process, Part Of The Material Near The Arc Of The Tool Edge Is Cut Off As Chips, The Other Part Is Squeezed To Produce Elastic Plastic Deformation. The Cutting Effect Of Ultra-Precision Machining Is Formed By The Cutting Rolling Effects Of The Tool, In The Process Of Forming The Machined Surface, The Accompanying Rolling Effect Accounts For A Large Proportion, That Is, The Quality Of The Machined Surface Is Largely Affected By The Rolling Effect.

CNC Precision Machining Manufacturers Precision Machining Technology Is One Of The Most Important Development Directions Of Modern Machinery Manufacturing Industry. It Plays A Vital Role In Improving The Performance Quality Of Electromechanical Products Developing High-Tech, Has Become A Key Technology For Success In International Competition. My Country's Manufacturing Industry Has Entered A Stage Of Rapid Development. The Introduction Of Advanced Equipment The Influx Of A Large Number Of Professional Talents Have Rapidly Improved The Manufacturing Level In Many Coastal Areas. With The Deepening Of The Scientific Democratic Process Of National Decision-Making, I Believe That My Country's Manufacturing Industry Will Develop Faster Healthier.
