Machinist – Form A1

This test was originally developed in 1989 as a 120-item, journey level test of machining job knowledge. Since then it has been revised several times and reduced to a 60-item test. This most recent revision involves minor edits to nine questions for grammar and clarity. Topic categories remain the same and are: Heat Treating; Layout, Cutting, & Assembly; Print Reading; Steel, Metals, & Materials; Rigging; Mechanical Principles & Repair; Machine Tools; Tools, Material, & Equipment; and Machine Shop Lubrication.
