Paper format. 16-Mec-B4 Integrated Manufacturing Systems, National Exams December 2018 — a three-hour open-book examination; any non-communicating calculator is permitted. The cover page states that “Any five (5) questions constitute a complete paper” and that only the first five as they appear in the answer book will be marked, and that “All questions are of equal value”, so each of the seven printed questions is worth 20 marks against a 100-mark paper. Note 1 invites the candidate to submit a clear statement of any assumptions made where a question is open to interpretation — this paper needs that licence twice, and both places are flagged below in a Check box. Note 5 warns that some answers are wanted in essay form, where clarity and organisation carry marks. All seven questions are worked here, because the set is a study resource rather than a timed attempt.

Canadian practice follows the same texts: CSA and ISO 9001 quality-system requirements sit above the chart methods used here, and CSA Z434 governs the safeguarding of the industrial robots discussed in Question 7.
