Intended Outcomes for the course

The student will understand and demonstrate advanced features and techniques in CNC programming and apply the knowledge to produce machined parts within required tolerances.
  • Apply advanced problem solving techniques with program verification.
  • Use various CNC controls with G and M codes and machine tool mechanics.
  • Manipulate advanced techniques of compensations for tool and cutter length, radii, and thread offsets.
  • Program set-ups for hole-machining and various milling and turning operations.
  • Apply commands for time reduction for machining and turning operations.
  • Determine appropriate use of various machining center accessory devices and changers common to the CNC environment.
  • Determine appropriate use of various turning center accessory devices and changers common to the CNC environment.

Course Activities and Design

ADVANCED CNC PROGRAMMING 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

 
POLICY - Student performance measurements are based on established industry standards. The various areas of study during the course will be evaluated by a variety of activities. Typical of those activities are the following;
1. READING ASSIGNMENTS - Information sheets, textbooks, journal articles and the learning resource center are potential sources of information that the student will reference as directed in the modules identified in the introduction. 
2. PRACTICE - Completion of tasks and projects identified in the reading assignments, information sheets, journal articles and textbooks. Students are required to complete practice activities with 100% competency.
3. SELF-ASSESSMENT - Checking and evaluating the students understanding and knowledge gained through the reading assignments and practices typically done through a practice evaluation.
4. 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.
5. 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.
