What Are The Methods Used By CNC Hardware Processing Manufacturers To Measure The Accuracy Of Workpieces?

　In The Process Of Mechanical Processing , Precision Is An Important Criterion For Measuring Product Quality. To Ensure Product Precision, The Selection Use Of Measuring Tools In CNC Hardware Processing Manufacturers Is Very Important. The Use Of Measuring Tools Must Follow The Maintenance, Inspection, Identification Plan Of Measuring Instruments To Ensure That The Measuring Tools Have Precision, Sensitivity, Accuracy. The Following CNC Hardware Processing Manufacturer Huiwen Will Specifically Introduce The Methods Of Obtaining Workpiece Dimensional Accuracy In Mechanical Processing, Which Are Mainly The Following:

(1) CNC Hardware Processing Factory Trial Cutting Method

　　That Is, First Try To Cut Out A Very Small Part Of The Processing Surface, Measure The Size Obtained By The Trial Cutting, The CNC Hardware Processing Manufacturer Appropriately Adjusts The Position Of The Tool Cutting Edge Relative To The Workpiece According To The Processing Requirements, Then Try Cutting, Then Measure. After Two Three Trial Cuttings Measurements, When The Processed Size Meets The Requirements, Cut The Entire Surface To Be Processed.

　　The Trial Cutting Method Is Repeated Through "Trial Cutting-Measurement-Adjustment-Retrial Cutting" Until The Required Dimensional Accuracy Is Achieved. For Example, The Trial Boring Processing Of The Box Hole System Of The CNC Hardware Processing Manufacturer.

　　The Trial Cutting Method May Achieve Very High Accuracy, It Does Require Complex Equipment, But This Method Is Time-Consuming (Requiring Multiple Adjustments, Trial Cutting, Measurement, Calculation), Inefficient, Dependent On The Worker's Technical Level The Accuracy Of The Measuring Instrument. The Quality Is Unstable, So It Is Only Used For Single-Piece Small-Batch Production.

　　As A Type Of Trial Cutting Method, Matching Is A Method Of Processing Another Workpiece That Matches The Processed Workpiece, Combining Two ( More) Workpieces Together For Processing. The Requirements For The Final Processed Size In Matching Are Based On The Matching Requirements Of The Processed Workpiece.

(2) Adjustment Method Of CNC Hardware Processing Manufacturers

　　Use Samples Standard Parts To Adjust The Exact Relative Positions Of Machine Tools, Fixtures, Tools Workpieces In Advance To Ensure The Dimensional Accuracy Of The Workpieces. Because The Dimensions Are Adjusted In Place In Advance, There Is No Need For Trial Cutting During Processing. The Dimensions Are Automatically Obtained Remain Unchanged During The Processing Of A Batch Of Parts . This Is The Adjustment Method. For Example, When A Milling Machine Fixture Is Used For Mechanical Processing, The Position Of The Tool Is Determined By The Tool Setting Block. The Essence Of The Adjustment Method Is To Use The Fixed-Range Device Tool Setting Device On The Machine Tool The Pre-Adjusted Tool Holder To Make The Tool Reach A Certain Position Accuracy Relative To The Machine Tool Fixture, Then Process A Batch Of Workpieces. Huiwen Zhizao Is A Machining Factory With More Than Ten Years Of CNC Processing Experience . It Has A Full Range Of Equipment, CNC Turning/Milling/Grinding/Drilling/Processing. Partners With Parts Processing Needs Are Welcome To Call Us For Quotes.

　　Feeding The Tool According To The Scale On The Machine Tool Then Cutting Is Also A Kind Of Adjustment Method. This Method Requires First Determining The Scale On The Scale By Trial Cutting. In Mass Production, Fixed-Range Blocks, Samples, Templates Other Tool Adjustment Devices Are Often Used.

　　The Adjustment Method Has Better Machining Accuracy Stability Than The Trial Cutting Method, Has Higher Productivity, Does Require High Machine Tool Operators, But Has High Requirements For Machine Tool Adjusters. It Is Often Used In Batch Production Mass Production.

(3) Sizing Method Of CNC Hardware Processing Manufacturers

　　The Method Of Using The Corresponding Size Of The Tool To Ensure The Size Of The Processed Part Of The Workpiece Is Called The Fixed Size Method. It Uses Standard Size Tools For Processing, The Size Of The Processed Surface Is Determined By The Tool Size. That Is, Using Tools With Certain Dimensional Accuracy (Such As Reamer, Reamer, Drill, Etc.) To Ensure The Accuracy Of The Processed Part Of The Workpiece (Such As Hole).

　　The Sizing Method Is Easy To Operate, Has High Productivity, Relatively Stable Processing Accuracy, Is Almost Independent Of The Worker's Technical Level. It Has High Productivity Is Widely Used In Various Types Of Production, Such As Drilling Reaming.

(4) Active Measurement Method Of CNC Hardware Processing Manufacturers

　　During The Machining Process, The Machining Dimensions Are Measured While Machining, After Comparing The Measured Results With The Dimensions Required By The Design, The Machine Tool Is Either Allowed To Continue Working Stopped. This Is The Active Measurement Method.

　　At Present, The Values In Active Measurement Can Be Displayed Digitally. Active Measurement Method Adds The Measuring Device To The Process System (I.E. The Unity Of Machine Tool, Tool, Fixture Workpiece), Becoming Its Fifth Factor.

　　Active Measurement Has Stable Quality High Productivity, Is The Development Direction. Huiwen Intelligent Manufacturing Has Long Been Committed To The Processing Of High-Precision, High-Difficulty, Easy-To-Deform Metal Plastic Parts , Small Medium-Volume Production Of Light Alloy Composite Material (Such As Aluminum Alloy, Carbon Fiber, Etc.) Parts,  Robot Parts Procurement Customization Services.

(5) Automatic Control Method Of CNC Hardware Processing Manufacturers

　　This Method Is Composed Of Measuring Device, Feeding Device Control System, Etc. It Combines The Measuring, Feeding Device Control System Into An Automatic Processing System, The Processing Process Is Completed Automatically By The System.

　　A Series Of Tasks Such As Dimension Measurement, Tool Compensation Adjustment, Cutting Processing, Machine Tool Parking Are Automatically Completed To Automatically Achieve The Required Dimensional Accuracy. For Example, When Processing On A CNC Machine Tool, The Parts Are Controlled By Various Instructions Of The Program To Control The Processing Sequence Processing Accuracy.

　　There Are Two Specific Methods Of Automatic Control:

　　① Automatic Measurement Means That The Machine Tool Is Equipped With A Device That Automatically Measures The Size Of The Workpiece. When The Workpiece Reaches The Required Size, The Measuring Device Will Issue A Command To Automatically Retract The Tool Stop Working.

　　② Digital Control Means That The Machine Tool Has A Servo Motor, A Ball Screw Nut Pair A Complete Set Of Digital Control Devices To Control The Precise Movement Of The Tool Holder Worktable. The Size Acquisition (The Movement Of The Tool Holder The Worktable) Is Automatically Controlled By A Pre-Programmed Program Through A Computer Digital Control Device. Metal Processing WeChat, The Content Is Good Worth Paying Attention To!

　　The Initial Automatic Control Method Was Completed By Active Measurement Mechanical Hydraulic Control Systems. At Present, It Is Widely Used To Control The Program According To The Processing Requirements, The Program-Controlled Machine Tools That Work By Issuing Instructions The Control System, The Digital Control Machine Tools That Work By Issuing Digital Information Instructions The Control System, The Adaptive Control Machine Tools That Can Adapt To The Changes In Processing Conditions During The Processing, Automatically Adjust The Processing Amount, Optimize The Processing Process According To The Specified Conditions For Automatic Control Processing.

　　Automatic Control Processing Has Stable Quality, High Productivity, Good Processing Flexibility, Can Adapt To Multi-Variety Production. It Is The Current Development Direction Of Mechanical Manufacturing The Basis Of Computer-Aided Manufacturing (CAM).

　　The Above Is An Introduction To The Methods Of Measuring The Accuracy Of Workpieces By CNC Hardware Processing Manufacturers. I Hope It Will Be Helpful To You.
