Computer Numerically Controlled Machine Tool Programmers, Metal and Plastic

Description

Develop programs to control machining or processing of metal or plastic parts by automatic machine tools, equipment, or systems.

Tasks

  • Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes.
  • Revise programs and/or tapes to eliminate errors, and retest programs to check that problems have been solved.
  • Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data in order to calculate dimensions, tool selection, machine speeds, and feed rates.
  • Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures.
  • Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications.
  • Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions.
  • Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers.
  • Write programs in the language of a machine's controller and store programs on media such as punch tapes, magnetic tapes, or disks.
  • Modify existing programs to enhance efficiency.
  • Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media.
  • Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.
  • Write instruction sheets and cutter lists for a machine's controller in order to guide setup and encode numerical control tapes.
  • Sort shop orders into groups to maximize materials utilization and minimize machine setup time.
  • Draw machine tool paths on pattern film, using colored markers and following guidelines for tool speed and efficiency.
  • Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards.

Interests

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.
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.
Artistic
Artistic occupations frequently involve working with forms, designs and patterns. They often require self-expression and the work can be done without following a clear set of rules.
Enterprising
Enterprising occupations frequently involve starting up and carrying out projects. These occupations can involve leading people and making many decisions. Sometimes they require risk taking and often deal with business.
Social
Social occupations frequently involve working with, communicating with, and teaching people. These occupations often involve helping or providing service to others.
