Machinists are an essential role within engineering, responsible for making the individual components required for producing all manner of machines and technologies. They are highly skilled at following precise blueprints and instructions to create items that meet precise requirements. Understanding the role and duties for a machinist can help you take steps to pursue this career. In this article, we discuss what machinists do, the training required to become a machinist, and the salary and career prospects for machinists.
What does a machinist do?
A machinist works in the engineering industry and utilises their knowledge of machinery to execute precise specifications set by engineers. This can include the examination of technical drawing and blueprints produced by engineers. In addition, a machinist must collaborate and communicate with the engineers to ensure that specific guidelines and drawings have been executed to plan.
Machinists carry out their work using a multitude of different tools depending on the job that is required. These tools can help the machinist measure, calculate, modify and cut materials to fit the technical brief. Some examples of their tools are as follows:
Drills and drilling machines
Machinists work with a variety of different materials, including but not limited to metal, wood, glass, ceramics, plastics and composites.
The machinists core role is to implement a solution from a drawing. The process begins by examining a blueprint drawing to understand and identify the specification of the project. Once this has been established, the machinist might start planning how he is going to execute the project by measuring, calculating, and cut the core materials. The final stage for the machinist is to work the necessary machinery to achieve the specific requirements on the original blueprint documentation.
What is a machinist?
Machinists are trained professionals who are highly skilled at using specialist equipment and machinery to shape materials (usually metal) into other items. They may repair existing machinery parts or craft entirely new parts. Machinists work on a wide variety of items, from small components like nuts, bolts and screws to larger components like pistons for hydraulic systems.
Machinists may specialise in creating unique, custom-built components or small batches of items to a precise specification, or repeatedly creating large numbers of the same item repeatedly. They usually work with metal, but can also create items using wood, glass, ceramics, rubber, plastics or a combination of different materials. They may work in factories, tool rooms, industrial facilities, research facilities, or even on military bases or ships. These work environments place a heavy emphasis on safety measures due to the hazards posed by heavy machinery and equipment.
What are the duties of a machinist?
The work of a machinist revolves around manufacturing items to specific requirements. To create small batches of items, machinists usually manufacture them manually using specialist machinery. For large-scale production, machinists may use computer numerically controlled (CNC) machines, which is automated, computer-guided machinery that shapes materials according to programmed settings. Using CNC machining tools also requires a great deal of expertise. The machinery needs to be set up properly, using the right settings and precautions, and then programmed to the exact specifications required for the items to be created.
Machinists may need to perform preliminary test runs with the machinery to ensure that the products are made to the correct standards. When manually creating items, machinists begin by studying the blueprints and specifications for the item to determine how to make it. They then measure the required materials using precision instruments, determine how to cut or shape them, and then use the necessary machining operations to create the item. This may involve using lathes, mills, drills and other equipment to turn, grind, drill or mill the item to the required specification.
What does a machinist do on a daily basis?
The manufacturing process used by machinists varies depending on the exact industry or facility that they work within. However, common machining tasks include:
Examining blueprints, technical drawings and specifications to understand the requirements for items
Configuring machinery as specified for parts
Using specialist tools to measure materials
Determining what speed to run materials through machines to obtain desired specs
Crafting items manually by using specialist machinery and equipment, usually involving milling, drilling, grinding and turning materials until they meet the required shape and dimensions
Using computer numerically controlled (CNC) machinery for automated large-scale production, ensuring the machinery is set to the correct specifications and overseeing its operation to make sure no errors occur
Coordinating with engineers, quality assurance or senior machinists to ensure the specifications for items are met and that the resulting parts are high enough quality
Working with others to maintain workplace safety
Performing necessary machine and equipment maintenance
