This competency-based curriculum guide for instructing students in using computer numerically controlled (CNC) turning machines is one of a series of instructional guides for the machinist field developed in Oklahoma. Although developed jointly with Baxter Technologies Corporation and oriented toward the Baxter Vo-Tec 2000 Future Builder CNC Lathe, the principles covered and learning experiences provided are readily transferable to other available machines. This curriculum guide contains six instructional units. Each unit is based on a standard format that includes eight basic components: performance objectives, instructional overviews for the instructor, information sheets, assignment sheets, job sheets, instructor supplements, tests, and answers to tests and assignment sheets. Depending on the specific objectives, there may or may not be instructor supplements, assignment sheets, and job sheets included in the unit of instruction. All of the unit components focus on measurable and observable learning outcomes. Units of instruction are designed for use in more than one lesson or class period. Units cover the following operations: perform preventive maintenance, power up the machine and control, set up machine and test run program, evaluate first run, perform production run, and write a program. A glossary of codes and abbreviations is included in the package. (KC)
