Namaste dosto! RRB ALP 2026 ki taiyari mein lage sabhi Machinist trade ke aspirants ka Unictest par swagat hai. Aaj hum ek aise topic par baat karne wale hain jo aapke trade test mein game-changer saabit ho sakta hai – Lathe Cutting Speed aur Feed. Maine personally dekha hai ki bahut se students is section ko ya toh mushkil samajhkar chhod dete hain ya sirf theory padhkar chale jaate hain. Lekin trust me, agar aap is topic ko achhe se prepare kar lete hain toh exam mein kam se kam 15-20 marks pakke hain, aur aap selection ke aur kareeb aa jaate hain!
Dekhiye, RRB ALP ka Stage 2, Part B, yaani ki Trade Test, aapke technical knowledge ko parakhta hai. Aur Machinist trade mein lathe machine ki cutting speed aur feed ki samajh bahut fundamental hai. Sirf definitions ratt lene se kaam nahi chalega, aapko iske formulas, calculations aur practical applications ki gehri samajh honi chahiye. Jab main apne students ko yeh topic padhata hoon, toh sabse pehle unhe bataata hoon ki yeh sirf kitaabi gyan nahi hai, yeh real workshop mein kaam aane wali cheez hai.
Cutting speed (Vc) ka matlab hai ki cutting tool kitni tezi se workpiece ki surface se material hata raha hai. Iski unit generally Meters per Minute (m/min) mein hoti hai. Sochiyega, agar speed sahi nahi hogi toh kya hoga? Agar speed bahut kam hai toh production slow hoga aur tool wear badhega. Agar speed bahut zyada hai toh tool jaldi ghis jayega ya toot bhi sakta hai, aur surface finish kharab ho jayegi. Isliye, sahi cutting speed calculate karna bahut critical hai. Iska formula sabko yaad hona chahiye:
Pichle 5 saal mein maine notice kiya hai ki is formula par based direct questions ya numericals zaroor aate hain. Students galti karte hain units mein, jaise diameter mm mein hai toh speed m/min mein nikalne ke liye 1000 se divide karna bhool jaate hain.
Feed (f) ka matlab hai ki cutting tool workpiece ke ek revolution mein kitna aage badhta hai. Iski unit generally mm per revolution (mm/rev) hoti hai. Feed rate decide karti hai ki workpiece se kitna material ek baar mein remove hoga. High feed rate se material removal rate badhta hai, lekin surface finish kharab ho sakti hai aur tool par load badh sakta hai. Low feed rate se surface finish achhi aati hai, lekin time zyada lagta hai.
Yeh factors samajhna bahut zaroori hai kyunki exam mein situational questions aa sakte hain. Jaise, 'Agar aapko Stainless Steel par turning karni hai, toh HSS tool ke liye cutting speed aur feed kya hogi?' Aise questions aapki conceptual clarity check karte hain.
Aap soch rahe honge ki sirf theory aur formulas padhne se kya exam clear ho jayega? Bilkul nahi! RRB ALP jaise competitive exams mein speed, accuracy aur time management bahut important hai. Aur yeh sab aata hai sirf aur sirf practice se. Unictest ke mock tests aapko ek real exam-like environment provide karte hain. Isse aapko pata chalta hai ki aap kahan stand karte hain, kaun se topics weak hain, aur time ke andar kitne questions attempt kar pa rahe hain.
Chaliye, ab kuch sawalon se apni samajh ko parkhte hain. Yeh questions RRB ALP Machinist trade test ke level ke hain.
Toh dekha aapne, yeh questions direct formulas aur concepts par based hain. Aise hi aur bhi questions aapko Unictest ke mock tests mein milenge. Yaad rakhiye – har topper bhi ek baar beginner tha. Bas consistency rakhiye aur lage rahiye!
