DMT-102 YCMOU Guess Paper, Solved PYQs, Notes 2026-27

DMT-102 Guess Paper & Solved PYQs: Your Direct Path to 90%+ Exam Accuracy

YCMOU’s Diploma in Mechanical Techniques (DMT-102) demands mastery of lathe operations, workshop safety, and dimensional tolerances—but only 30% of students pass the TEE on first attempt due to ambiguous question patterns. This Solved Previous Year Question (PYQ) Bank eliminates guesswork by providing 100+ verified questions from YCMOU’s 2023–2026 archives, meticulously mapped to the Turning-Lathe Operator curriculum (Units 1–6). Each solution includes hand-drawn workshop sketches for taper turning, thread cutting, and offset drilling—exactly what examiners expect in TEE Part B (Practical Theory).

Academic Objectives Aligned with YCMOU’s DMT-102 Syllabus

This resource targets the core competencies outlined in YCMOU’s Self-Instructional Material (SIM) for DMT-102, ensuring alignment with:

• Unit 1: Lathe Machine Fundamentals – 18 solved questions on bed types (plain vs. turret), spindle speeds (RPM calculations), and tool geometry (ISO vs. ANSI standards).
• Unit 3: Taper Turning & Thread Cutting – 22 step-by-step solutions with tailstock offset formulas and pitch measurements for metric/imperial threads (e.g., M12 × 1.75 vs. 60° UNC).
• Unit 5: Workshop Safety & Quality Control – 15 CA-relevant questions on ISO 9001:2015 tolerances (e.g., IT6 for shaft diameters) and PPE compliance for grinding operations.

Continuous Assessment (CA) & Term-End Exam (TEE) Utility

The gृहपाठ (Home Assignment) section includes 12 model answers for Unit 2 (Workshop Layout) and Unit 4 (Drilling & Boring), formatted to YCMOU’s marking scheme (30% for theory, 40% for calculations, 30% for diagrams). For the TEE:

• Part A (20 marks) – Short-answer focus on lathe attachments (e.g.,
