Competencies for production machine shop are provided for the fourth of four topic areas: the milling machine. Each competency appears in a one-page format. It is presented as a goal statement followed by one or more "indicator" statements, which are performance objectives describing an ability that, upon attainment, will establish competency for the stated goal. Indicator statements are further qualified by one or more "benchmark" statements or observable behaviors describing what the trainee will do to prove that he/she is demonstrating achievement of the performance objective. Benchmark statements are followed by an "assessment" statement, which describes how the observer determines that the benchmark is achieved and establishes the criteria for performance. The competencies for this topic are divided into 10 sections: milling machine classifications, holding devices and attachments, milling cutters, milling operations, slab milling, face milling, straddle milling and milling a slot, sawing and gang milling, milling a square on a straddle mill, and vertical milling machine.
