Technical Report on Occupations in Numerically Controlled Metal-Cutting Machining.
Manpower Administration (DOL), Washington, DC. U.S. Employment Service.
At the present time, only 5 percent of the short-run metal-cutting machining in the United States is done by numerically controlled machined tools, but within the next decade it is expected to increase by 50 percent. Numerically controlled machines use taped data which is changed into instructions and directs the machine to do certain steps automatically and then test its own performance. This report compares requirements for operators of numerically controlled machines with conventional machines in terms of training, experience, aptitudes, interests, temperaments, physical demands, and working conditions, and discusses the implications of automatic drafting machines, digitizing machines, computer programing, manual parts programing, tool design and presetting, and program, tooling, and tape testing for the industry. The second part of the study provides job descriptions for department planning, part programing, tool presetting, electronics maintenance, and 3 categories of operators which include job machine boring, milling machine, and vertical turret lathe operators. A glossary of terms and a bibliography are appended. (BC)
