CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a cutting tool is fed to the piece to remove material to create the desired shape. This process is typically used to create round or tubular shapes， इसके अतिरिक्त, CNC turning allows the generation of complex external geometries and internal holes, including the machining of various threads、hexagons.
सामग्री चयन: The process begins with choosing an appropriate material for the workpiece, which could be metal, प्लास्टिक, लकड़ी, or other materials.
Clamping: The workpiece is clamped into the chuck of the CNC lathe. The chuck holds the workpiece securely and rotates it during the machining process.
CAD/CAM Software: Engineers use Computer-Aided Design (पाजी) software to create a detailed model of the part to be produced. This model is then imported into Computer-Aided Manufacturing (कैम) software to generate the machining instructions.
जी कोड: The CAM software translates the design into G-code, a language CNC machines understand. This code contains all the instructions for tool movements, spindle speeds, feed rates, और अन्य पैरामीटर.
उपकरण चयन: The appropriate cutting tools are selected and loaded into the turret of the CNC lathe. Common tools include turning tools, boring bars, and threading tools.
Tool Calibration: Each tool is calibrated to ensure it is correctly positioned relative to the workpiece. This involves setting the tool offsets and ensuring the machine’s coordinate system is properly aligned.
Spindle Rotation: The CNC lathe's spindle rotates the workpiece at a predetermined speed. The speed is selected based on the material and the desired surface finish.
Tool Movement: Holding the cutting tools, the turret moves along the X and Z axes (and sometimes the Y axis) to engage the tools with the rotating workpiece. The CNC system precisely controls the movement.
सामग्री हटाना: The cutting tool removes material from the workpiece in a controlled manner.
In-Process Inspection: As the machining progresses, measurements are taken to ensure the part meets the specified dimensions and tolerances. This can involve manual measurements or automated probing systems.
अंतिम निरीक्षण: Once the machining is complete, the part is removed from the machine and undergoes a thorough inspection for dimensional accuracy, सतह खत्म, and other quality criteria.
Deburring and Finishing: The machined part is often subjected to additional processes such as deburring (removing sharp edges), घर्षण, or coating to achieve the desired final properties.
विधानसभा: If the part is a component of a larger assembly, it may be assembled with other parts as required.
CNC turning encompasses various operations performed on a turning center, शामिल:
शुद्धता: CNC turning provides high precision and repeatability, ensuring consistent quality across multiple parts.
क्षमता: Automated control reduces the time required for setup and machining, उत्पादन क्षमता में वृद्धि.
जटिल आकार: Capable of producing complex geometries and intricate details that would be difficult or impossible to achieve manually.
FLEXIBILITY: Suitable for a wide range of materials and applications, from prototyping to mass production.
Reduced Labor: Minimizes the need for manual intervention, reducing the risk of human error and improving safety.
सीएनसी मिलिंग मुख्य रूप से वर्कपीस की सतह पर उपकरण को घुमाने और घुमाने से की जाती है और अक्सर इसका उपयोग फ्लैट को संसाधित करने के लिए किया जाता है, घुमावदार सतहें और भागों के जटिल आकार, जैसे गियर, धारणीयता, भागों के गोले, और इसी तरह.
सीएनसी टर्निंग मुख्य रूप से वर्कपीस को घुमाने और वर्कपीस पर उपकरण से काटने के द्वारा महसूस की जाती है और इसका उपयोग अक्सर बेलनाकार आकार के भागों को संसाधित करने के लिए किया जाता है।, जैसे शाफ्ट, बीयरिंग, धागे, वगैरह.
दोनों प्रक्रियाएं, मोड़ना और मिलिंग करना, अवांछित सामग्री को हटाने के लिए घटिया विनिर्माण का उपयोग करें, अपशिष्ट चिप्स का उत्पादन. वे स्टॉक सामग्री में भिन्न हैं, मशीनिंग के तरीके, और उपकरण लेकिन दोनों उन्नत सीएनसी तकनीक का उपयोग करते हैं. इंजीनियर CAD सॉफ़्टवेयर का उपयोग करके मशीनों को प्रोग्राम करते हैं, पर्यवेक्षण को कम करना और मानवीय त्रुटि को कम करना, जो लगातार गुणवत्ता के लिए गति और विश्वसनीयता को बढ़ाता है.
एल्यूमीनियम जैसी धातुओं के लिए टर्निंग और मिलिंग उपयुक्त हैं, इस्पात, पीतल, ताँबा, और टाइटेनियम, साथ ही विभिन्न थर्मोप्लास्टिक्स. तथापि, वे रबर और सिलिकॉन जैसी सामग्रियों के लिए उपयुक्त नहीं हैं (बहुत नरम) या चीनी मिट्टी (बहुत कठिन).
दोनों तकनीकें गर्मी उत्पन्न करती हैं और इस समस्या को प्रबंधित करने के लिए अक्सर काटने वाले तरल पदार्थ का उपयोग करती हैं.
CNC Milling is generally considered the most recommended method for producing parts with complex shapes, while CNC Turning is equally good for simpler, round shapes.
Nonetheless, Both CNC Milling and CNC Turning can be used sequentially when a part requires both complex shapes and cylindrical features. because there may be situations where both operation processes are required.
