Course Description

Introduces basic operation and setup skill used with Fanuc (G&M compatible) controlled CNC turning centers. This course is also offered as APR 279M; a student who enrolls in this course a second time under either designator will be subject to the course repeat policy. Prerequisites: APR 259M or MCH 259. Audit available.

Addendum to Course Description

CNC Machine Panels - In this module the student is introduced to the functions of the Buttons, Switches and Keys found on CNC Machine Control Units (MCU) for the control of the functions of the control panel display, machine operation, feed, spindle speed, tool changing, axis motion, automatic and manual operation of the machine tool.

CNC Modes - In this module the student is introduced to the five CNC Modes of Operation; Manual; Manual data Input (MDI); Edit; Program Operation - Memory (Automatic) & Tape.

CNC Key Sequences - In this module the student is introduced to the Key Sequences of CNC machine operation for Turning Centers.

CNC Program Verification - In this module the student is introduced to the Concepts of CNC Program Verification such as: Safety Priorities; Running Good Parts; and Verification of Programs.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Understand and apply machine shop safety concepts and safety practices.

  • Understand and demonstrate fundamental CNC lathe operation to produce machined parts within required tolerances.  

  • Explain the functions of the buttons, switches, and keys found on CNC machine control unit (MCU).

  • Perform and control the functions of the control panel display, machine operation, feed, spindle speed, tool changing, axis motion, and automatic and manual operation of the machine tool.

  • Demonstrate the five CNC modes of operation: manual, manual data input (MDI), edit, program operation, and memory (automatic and tape).

  • Perform key sequences of CNC lathe operation for turning centers and CNC program verification.

Course Activities and Design

CNC OPERATION - LATHE will be presented by means of audiovisual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge competencies prescribed by business and industry performance standards. The identified competencies will be achieved by means of individual and team activities.  

Outcome Assessment Strategies

1. LAB ACTIVITIES - Participation in structured laboratory exercises with the emphasis on developing skills or increasing expertise in the areas of study identified in the module packets.

2. FINAL ASSESSMENT - An assessment in the form of a written exam and/or practical application that addresses the subject areas identified in the module packets. Students are required to complete final assessment activities with 85% competency.
