- Machinists perform some or all of the following duties:
- - Read and interpret engineering drawings, blueprints, charts and tables or study sample parts to determine machining operation to be performed, and plan best sequence of operations
- - Compute dimensions and tolerances and measure and lay out work pieces
- - Set up, operate and maintain a variety of machine tools including computer numerically controlled (CNC) tools to perform precision, non-repetitive machining operations such as sawing, turning, milling, boring, planing, drilling, precision grinding and other operations
- Continued…
- - Fit and assemble machined metal parts and subassemblies using hand and power tools
- - Verify dimensions of products for accuracy and conformance to specifications using precision measuring instruments
- - May set up and program machine tools for use by machining tool operators.
- Machining and tooling inspectors perform some or all of the following duties:
- - Verify dimensions of machined parts or tooling using micrometers, verniers, callipers, height gauges, optical comparators, co-ordinate measuring machines (CMM) or other specialized measuring instruments
- - Maintain, repair and calibrate precision measuring instruments such as dial indicators, fixed gauges, height gauges and other measuring devices
- - Report deviations from specifications and tolerances to supervisor
- - Complete and maintain inspection reports.
