Most Repeated CNC Interview Questions and Answers
Q1. CNC full form kya hai aur yeh kaise kaam karti hai?
Ans. CNC ka full form Computer Numerical Control hai. Yeh ek aisi automated machine hoti hai jo computers me feed kiye gaye coded instructions (G-codes aur M-codes) ke mutabik materials ko bohot hi precision aur accuracy se kaat-ti ya shape karti hai.
Q2. G-Code aur M-Code me kya antar (difference) hota hai?
Ans. G-Codes (Preparatory Codes) machine ke tool ki movement ko control karte hain (jaise tool ko kahan jana hai, straight chalna hai ya circle me chalna hai).
M-Codes (Miscellaneous/Machine Codes) machine ke baki operations ko handle karte hain (jaise coolant ko ON/OFF karna, spindle ko ghumana, ya program ko stop karna).
Q3. G00 aur G01 code me kya fark hai?
Ans. G00 ka matlab hota hai **Rapid Positioning** (tool ko bina cutting kiye tez raftar me kisi point tak le jana). G01 ka matlab hota hai **Linear Interpolation** (tool ko ek fixed feed rate par material kaat-te huye straight line me aage badhana).
Q4. Tool Offset kya hota hai aur yeh kyun liya jata hai?
Ans. Tool offset machine ko har ek tool ki exact lambai (length) aur motai (radius) batane ke liye liya jata hai. Isse machine ko pata chalta hai ki cutting edge kis point par hai, taaki component dimensional limit ke andar ekdum perfect bane.
Q5. CNC Machine me Feed Rate se aap kya samajhte hain?
Ans. Cutting tool machine chalne ke dauran ek minute me ya ek revolution me workpiece ke andar kitni door tak travel karta hai, use Feed Rate kehte hain. Isko aamtaur par mm/min ya mm/rev me measure kiya jata hai.
