Machinists set up and operate a variety of machine tools to cut or grind metal, plastic or other materials to make or modify parts or products with precise dimensions. Machining and tooling inspectors inspect machined parts and tooling in order to maintain quality control standards. They are employed by machinery, equipment, motor vehicle, automotive parts, aircraft and other metal products manufacturing companies and by machine shops. Apprentices are also included in this unit group.
Machinists 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
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
Verify dimensions of machined parts or tooling using micrometers, verniers, callipers, height gauges, optical comparators, coordinate 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.
