Details for Machinists


Description

Set up and operate a variety of machine tools to produce precision parts and instruments. Includes precision instrument makers who fabricate, modify, or repair mechanical instruments. May also fabricate and modify parts to make or repair machine tools or maintain industrial machines, applying knowledge of mechanics, shop mathematics, metal properties, layout, and machining procedures.

Tasks

  • Calculate dimensions and tolerances using knowledge of mathematics and instruments such as micrometers and vernier calipers.
  • Machine parts to specifications using machine tools such as lathes, milling machines, shapers, or grinders.
  • Measure, examine, and test completed units to detect defects and ensure conformance to specifications, using precision instruments such as micrometers.
  • Set up, adjust, and operate all of the basic machine tools and many specialized or advanced variation tools to perform precision machining operations.
  • Align and secure holding fixtures, cutting tools, attachments, accessories, and materials onto machines.
  • Monitor the feed and speed of machines during the machining process.
  • Study sample parts, blueprints, drawings, and engineering information to determine methods and sequences of operations needed to fabricate products, and determine product dimensions and tolerances.
  • Select the appropriate tools, machines, and materials to be used in preparation of machinery work.
  • Lay out, measure, and mark metal stock to display placement of cuts.
  • Observe and listen to operating machines or equipment to diagnose machine malfunctions and to determine need for adjustments or repairs.
  • Check work pieces to ensure that they are properly lubricated and cooled.
  • Maintain industrial machines, applying knowledge of mechanics, shop mathematics, metal properties, layout, and machining procedures.
  • Position and fasten work pieces.
  • Operate equipment to verify operational efficiency.
  • Install repaired parts into equipment, or install new equipment.
  • Clean and lubricate machines, tools, and equipment to remove grease, rust, stains, and foreign matter.
  • Advise clients about the materials being used for finished products.
  • Program computers and electronic instruments such as numerically controlled machine tools.
  • Set controls to regulate machining, or enter commands to retrieve, input, or edit computerized machine control media.
  • Confer with engineering, supervisory, and manufacturing personnel to exchange technical information.
  • Dismantle machines or equipment, using hand tools and power tools, to examine parts for defects and replace defective parts where needed.
  • Establish work procedures for fabricating new structural products, using a variety of metalworking machines.
  • Support metalworking projects from planning and fabrication through assembly, inspection, and testing, using knowledge of machine functions, metal properties and mathematics.
  • Confer with numerical control programmers to check and ensure that new programs or machinery will function properly, and that output will meet specifications.
  • Fit and assemble parts to make or repair machine tools.
  • Evaluate experimental procedures, and recommend changes or modifications for improved efficiency and adaptability to setup and production.
  • Design fixtures, tooling, and experimental parts to meet special engineering needs.
  • Prepare working sketches for the illustration of product appearance.
  • Install experimental parts and assemblies such as hydraulic systems, electrical wiring, lubricants, and batteries into machines and mechanisms.
  • Set up and operate metalworking, brazing, heat-treating, welding, and cutting equipment.
  • Test experimental models under simulated operating conditions for such purposes as development, standardization, and feasibility of design.

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.
  • Investigative - Investigative occupations frequently involve working with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.
  • Conventional - Conventional occupations frequently involve following set procedures and routines. These occupations can include working with data and details more than with ideas. Usually there is a clear line of authority to follow.

Education, Training, Experience

  • Education - Most occupations in this zone require training in vocational schools, related on-the-job experience, or an associate's degree.
  • Training - Employees in these occupations usually need one or two years of training involving both on-the-job experience and informal training with experienced workers. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Previous work-related skill, knowledge, or experience is required for these occupations. For example, an electrician must have completed three or four years of apprenticeship or several years of vocational training, and often must have passed a licensing exam, in order to perform the job.

Knowledge

  • English Language - Knowledge of the structure and content of the English language including the meaning and spelling of words, rules of composition, and grammar.
  • Design - Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models.
  • Engineering and Technology - Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services.
  • Production and Processing - Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.
  • Mathematics - Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
  • Mechanical - Knowledge of machines and tools, including their designs, uses, repair, and maintenance.
