This student guide provides materials for a course designed to introduce the student to the operations and functions of a two-axis computer numerical control (CNC) turning center. The course consists of seven units. Unit 1 presents course expectations and syllabus, covers safety precautions, and describes the CNC turning center components, CNC control panel, and cathode ray tube (CRT). Unit 2 teaches manual operation of the machine tool axes and spindle for the purpose of homing or orientating the machine tool, manual tool loading and turret indexing, tail stock positioning, and soft key and CRT menu functions. Unit 3 prepares the operator to execute short programs created through the use of the Manual Data Input mode of the control panel and the exit mode. Unit 4 introduces a method of setting up the CNC turning center machine tool and program verification or prove-out procedures. Unit 5 introduces a new and unique concept in lathe tooling systems--Quick Setter and Quick Change Tool. Unit 6 instructs the student in canned cycle machining. Unit 7 introduces the set-up and operation of part programs that require the use of the tailstock for threading and grooving operations. Contents of each unit include an introduction, list of objectives, contents, and materials for three sections. These sections contain narrative instructional materials, an assignment section that requires written answers, a project section with instructions and necessary data sheets, and competency check list.
