Machinists and machining and tooling inspectors

Other titles : aircraft engine parts machinist, aircraft machinist, apprentice automotive machinist, auto parts machine shop inspector, computer-assisted machinist, differential gear testing machinist, electrical machinist, gear inspector-machinist, gear tester-machinist, general machinist, precision machinist, printing press machinist, tooling inspector, toolroom inspector, toolroom machinist


Description :

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.

Main 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
  • 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

Admission requirements for an AVS

To enroll in an AVS program, a DVS or equivalent experience in a related field is required. The AVS is issued upon the successful completion of a program that upgrades skills or provides specialization in a particular trade or occupation. 


Diploma of Collegial Studies (DCS)


Mechanical Engineering Technology

Program Lenght: 3 years

Program objectives

The purpose of this program is to train technicians to carry out the technical design of different components and mechanical systems, to plan manufacturing and to take care of quality control. Mandatory competencies (23) from the specific training category aim to ensure the versatility of graduates and to enable them to work equally in the fields of design and manufacturing. The category entitled elective competencies (7 competencies) aims at the development of competencies in the particular fields such as: development of manufacturing range, programming of machines with numerical control, design and the manufacturing of tools, industrial lines and mechanical systems with their frame, the manufacturing of prototypes, quality control, the planning of the maintenance of machinery, the organization and the coodination of production, technological survey and research and development. This program will contribute to the development and training of students in the following capacities: to include/understand and apply all directives in relation to their work (to establish interpersonal relationships, to work as a team and to adapt to changes), to plan and organize their work with an emphasis on productivity (accuracy, precision, quality, time limits), good judgement, communicate orally and written in French, to bring in new ideas and solutions, defend a project or an idea, use production equipment, to have continuous improvement and to learn individually.

Other training

Occupation targeted under the Workplace Apprenticeship Program.

This program was created by Commission des partenaires du marché du travail and Emploi-Québec in partnership with sector-based labor force committees.

It supports workplace apprenticeship and skill recognition programs.

Training and skill evaluation are under the supervision of an experienced worker. Once the apprenticeship is finished and skills are mastered by the apprentice, a certificate of qualification is issued and recorded in a government registry.

For more information on the Workplace Apprenticeship Program, see the Emploi-Québec website
