(Undercut Diameter): The diameter of the recessed portion. It is always smaller than the minor diameter of the thread. (Undercut Width): The longitudinal width of the recess. While technical standards like DIN 76-1 aren't usually

Section B — Interpretation and application (30 points) 5. Given a cylindrical shaft end with diameter 20 mm requiring a chamfer per DIN 76‑A, specify the chamfer dimensions and tolerances you would apply. Show how you derived them from the standard (assume typical tolerance class m if needed). (10 pts)
6. You are preparing a technical drawing that must reference DIN 76‑A for chamfering. Draft the exact drawing note text to place on the drawing (one line). Also specify the appropriate symbol or leader placement. (6 pts)
7. A supplier delivers parts with chamfers that visually conform but measure 0.2 mm larger than the nominal chamfer specified by DIN 76‑A. Discuss whether this is acceptable, referencing tolerance interpretation and functional fit (assume nominal chamfer 1.6×45°). (8 pts)
8. Identify two manufacturing processes suitable for producing DIN 76‑A chamfers on mild steel, and list one quality-control check for each. (6 pts) * Scope
