Details for Drilling and Boring Machine Tool Setters, Operators, and Tenders, Metal and Plastic


Description

Set up, operate, or tend drilling machines to drill, bore, ream, mill, or countersink metal or plastic work pieces.

Tasks

  • Verify conformance of machined work to specifications, using measuring instruments, such as calipers, micrometers, or fixed or telescoping gauges.
  • Study machining instructions, job orders, or blueprints to determine dimensional or finish specifications, sequences of operations, setups, or tooling requirements.
  • Select and set cutting speeds, feed rates, depths of cuts, and cutting tools, according to machining instructions or knowledge of metal properties.
  • Install tools in spindles.
  • Change worn cutting tools, using wrenches.
  • Position and secure workpieces on tables, using bolts, jigs, clamps, shims, or other holding devices.
  • Move machine controls to lower tools to workpieces and to engage automatic feeds.
  • Turn valves and direct flow of coolants or cutting oil over cutting areas.
  • Operate single- or multiple-spindle drill presses to bore holes so that machining operations can be performed on metal or plastic workpieces.
  • Establish zero reference points on workpieces, such as at the intersections of two edges or over hole locations.
  • Observe drilling or boring machine operations to detect any problems.
  • Lift workpieces onto work tables either manually or with hoists or direct crane operators to lift and position workpieces.
  • Lay out reference lines and machining locations on work, using layout tools, and applying knowledge of shop math and layout techniques.
  • Perform minor assembly, such as fastening parts with nuts, bolts, or screws, using power tools or hand tools.
  • Verify that workpiece reference lines are parallel to the axis of table rotation, using dial indicators mounted in spindles.
  • Operate tracing attachments to duplicate contours from templates or models.
  • Sharpen cutting tools, using bench grinders.

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 - These occupations usually require a high school diploma.
  • Training - Employees in these occupations need anywhere from a few months to one year of working with experienced employees. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Some previous work-related skill, knowledge, or experience is usually needed. For example, a teller would benefit from experience working directly with the public.

Knowledge

  • Design -Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models.
  • Mathematics -Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
  • Mechanical -Knowledge of machines and tools, including their designs, uses, repair, and maintenance.
