This curriculum guide was developed from a Technical Committee Report prepared with the assistance of industry personnel and containing a Task List which is the basis of the guide. It presents competency-based program standards for courses in precision machining technology and is part of the Idaho Vocational Curriculum Guide Project, a cooperative effort among secondary and postsecondary instructors and administrators and business representatives. The purpose of the program is to prepare students for employment as machinists, filers, grinders, buffers, lay out workers, mill operators, or computer numerically controlled machine operators, or to provide supplemental training for persons already employed in these occupations. Areas covered in the guide include communication skills, leadership skills, human relations and employability skills, safe and efficient work practices, shop mathematics and blueprints, shaping metal parts, bench work, precision measurement, layout, and inspection. The guide contains a task profile that outlines the curriculum and 13 task listings and performance standards that correspond to the 13 modules in the guide. The modules cover the following topics: employability skills, prerequisite machining, bench work, power saws, pedestal grinders, drill presses, lathes, milling machines, surface grinding machining, tool and cutter grinding machines, computerized numerical control, electric discharge machines, and heat and treat furnaces. Each module consists of an introduction and a list of tasks correlated to a performance objective and a list of enabling objectives. (KC)
