Scope

Machinists possess the knowledge and abilities to set up and operate machines that cut or grind metal and other materials into products with precise dimensions. These machines include lathes, milling machines, saws, grinding machines, drilling machines and boring machines.

Machinists work from drawings, specifications and their own measurements to calculate dimensions, tolerances and types of fit. They must be knowledgeable about the properties of metal, plastic, rubber and composite materials.

Precise measurements are critical to machinists’ work. Machinists operate conventional and Computer Numerical Control (CNC) machine tools.

Machinists may work in industries where machines are manufactured, repaired or used. These may include industries that manufacture machinery equipment, motor vehicle parts or aerospace parts. The machinist machines precision parts that are used in all aspects of manufacturing. They also work in shipyards, railyards, refineries, pulp and paper mills, mines, smelters and metal fabricating and overhaul shops. Shiftwork is common in some companies. Machinists tend to work indoors.

Safety is important at all times. There are risks of injury working with moving machine parts, sharp edges and extreme heat from heated materials. Precautions are required while working with manufacturing chemicals and airborne irritants.

Key attributes for people entering this trade are: communication skills, mechanical aptitude, hand-eye coordination, manual dexterity, an ability to work independently, and an understanding of mathematics and physics. Physical condition is important because the work often requires considerable standing and handling heavy objects. This analysis recognizes similarities or overlaps with the work of other tradespeople such as tool and die makers, mould makers, welders and industrial mechanics (millwrights).

Experienced machinists may move into supervisory positions. With additional training they may transfer their skills to related occupations such as tool and die maker, mould maker, industrial mechanic (millwright) or CNC programmer.

Observations

Computer numerical control (CNC) machining has transformed and continues to transform the work of machinists. It is now used in even low production runs where manual machines had previously been used. CNC machines are programmed by machinists or dedicated programmers, but as CNC machines become more versatile, the number of manual machines declines. There is also an increased use of hybrid machines (manual/CNC).

There will still be a need for highly trained machinists who have the knowledge and expertise of conventional machining.

Safety

Safe working procedures and conditions, accident prevention and the preservation of health are of primary importance to industry in Canada. These responsibilities are shared and require the joint efforts of government, employers and employees. It is imperative that all parties become aware of circumstances that may lead to injury or harm. Safe learning experiences and work environments can be created by controlling the variables and behaviours that may contribute to accidents or injury.

It is generally recognized that safety-conscious attitudes and work practices contribute to a healthy, safe and accident-free work environment.

It is imperative to apply and be familiar with the Occupational Health and Safety Acts and Workplace Hazardous Material Information System (WHMIS) Regulations. As well, it is essential to determine workplace hazards and take measures to protect oneself, co-workers, the public and the environment.

As safety education is an integral part of training in all jurisdictions, personal safety practices are not recorded in this document. However, the technical safety aspect relating to each task and sub-task are included throughout this analysis.
