What are the steps of CNC machining?

In today’s era of rapid technological development, CNC machining has become an indispensable part of the manufacturing industry. It not only provides high-precision and high-efficiency solutions for the machining of various complex parts, but also promotes the continuous advancement of science and technology. So, what are the basic steps of CNC machining? Let’s take a closer look at CNC Processing Steps.

first stepDesign and programming

Before CNC machining,Primero, you need to program according to the design requirements of the part.This step is like drawing a preciseblueprintfor CNC machiningDesigners use professional computer-aided design (CANALLA) softwarethe shape of the partsizeAccuracy and other requirements to draw accuratelyThenThrough computer-aided manufacturing (CAM) softwareConvert the designed part model into a processing program that can be recognized by CNC machine toolsThis program contains the movement path of the toolCutting parametersDetailed information such as feed speedIt is the core instruction of CNC machiningduring programmingProgrammers need to fully consider the material of the partshapeFactors such as processing technologyto ensure program accuracy and feasibility

Step 2:Preparation

After programming is completedIt is necessary to carry out preparation work before processingThis includes choosing the right toolFixtures and raw materialsTool selection is crucial to the efficiency and quality of CNC machiningDifferent machining processes require different types of toolsSuch as milling cutterdrillReamer etc.The function of the clamp is to firmly fix the raw materials on the machine toolTo ensure the position accuracy of parts during processingat the same timeCheck raw materialsEnsure its quality meets processing requirementsalsoCNC machine tools also need to be debugged and warmed upCheck whether the performance of the machine tool is normalPrepare for subsequent processing

Step 3:Clamping the workpiece

Clamping the prepared raw materials onto the CNC machine tool is a critical stepDuring the clamping processEnsure that the position of the workpiece is accurateStrong and reliablefirstNeed to clean the oil stains on the surface of the workpieceImpurities such as iron filings and dustSo as not to affect the processing accuracyThenAccording to the shape and processing requirements of the workpieceChoose the appropriate clamping methodSuch as chuck clampingPressure plate clamping, etc.。For some workpieces with complex shapesSpecial fixtures may be requiredDuring the clamping processBe careful to avoid collisions between the workpiece and other parts of the machine toolAt the same time, ensure that the tool has enough space to move during processing.

Step 4:Tool setting and zero point setting

Tool setting is an important link in CNC machiningIts purpose is to determine the relative position between the tool and the workpieceSo that the machine tool can accurately process according to the programTool setting is usually performed using a tool setter or trial cutting method.After tool setting is completedNeed to set the zero point of the workpieceThat is the reference point of processingThe position of this zero point will be used as the origin of the machine tool coordinate system.All processing dimensions are determined relative to this zero pointWhen setting zero pointto ensure its accuracySo as not to affect the processing accuracy

Step 5:Parameter settings

before starting processingIt is also necessary to set various parameters of the machine tool according to the requirements of the processing technology.Such as spindle speed、Velocidad de alimentación、Cutting depth, etc.。The choice of spindle speed depends on the diameter of the toolmaterials and processing techniques to determineGenerally speakingThe larger the tool diameterThe lower the spindle speedFeed speed affects processing efficiency and surface qualityToo fast or too slow feed speed may cause processing quality problemsThe cutting depth should be determined according to the material and processing requirements of the workpieceExcessive cutting depth may damage the tool or machine toolToo small a cutting depth will affect processing efficiency.

Step 6:Processing operations

When all preparations are completedYou can start CNC machiningThe operator inputs the written processing program into the control system of the CNC machine toolThen start the machineThe machine tool will automatically process according to the instructions of the programduring processingOperators should pay close attention to the operating status of machine toolsPay attention to the movement trajectory of the toolcutting soundVibration of machine tools, etc.,If there is any abnormality, stop the machine immediately for inspection.at the same timeAccording to the actual situation of processingAdjust processing parameters timelyTo ensure processing quality and efficiency

Step 7:Quality inspection

After processing is completedNeed to check the quality of partsThe content of the inspection includes the dimensional accuracy of the partsShape accuracySurface quality, etc.。Commonly used inspection tools include calipersmicrometerThree coordinate measuring instrument, etc.。If it is found that the quality of the parts does not meet the requirementsAnalyze the reasons promptlyand take appropriate measures to improvesuch as reprocessingAdjust processing parameters, etc.。

The continuous development of CNC machining technologybrought huge changes to the manufacturing industryIt not only improves production efficiency and product qualityAlso for the intelligence of manufacturing industryAutomation development provides strong support。Por ejemplo,in aerospaceautomobile manufacturingMold processing and other fieldsCNC machining technology has been widely usedWith the continuous advancement of technologyCNC machining technology will continue to innovate and improveBringing more opportunities and challenges to the development of manufacturing industry
