National Examinations, May 2019 — 17-Ind-B2 Manufacturing Processes. 3-hour closed-book exam; candidates may use a Casio or Sharp approved calculator. Any five questions constitute a complete paper (only the first five as they appear are marked officially); all seven are answered below as a full study resource.

Reference texts. Groover, Fundamentals of Modern Manufacturing: Materials, Processes, and Systems, 6th ed. (primary text for this subject — material selection, casting, polymer processing, metal forming, powder metallurgy, and machining).

Check: every page’s printed footer reads “17-Ind-B2/May 2019”, so this is the May 2019 sitting. In Question 1(ii), option (3) is "Bending". Question 1 uses a multiple-choice (statement-selection) format.
