CNC Setup Time Reduction - In this module the student is introduced to Setup Time Reduction Principles and Techniques such as: the Importance of; Setup Time Defined; Preparation and Organization; for machining and turning Centers; Program Zero Assignment; Cutting Tool Issues; program Development - Loading, Verification, and Optimizing; and Inspection.

CNC Cycle Time Reduction - In this module the student is introduced to Cycle Time Reduction Principles and Techniques such as: Workpiece Loading/Unloading; Program Execution; Tool Maintenance Time; and Preventative/Corrective Maintenance.  

PREREQUISITE SKILLS AND KNOWLEDGE:  
MCH 259 & MCH 268  

  
The student will demonstrate understanding of CNC setup and cycle time reduction by the application of the techniques to a specific CNC program.

 
This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding of the following:

• Setup Time Reduction Principles and Techniques such as the Importance of; Setup Time Defined; Preparation and Organization; for machining and turning Centers; Program Zero Assignment; Cutting Tool Issues; program Development - Loading, Verification, and Optimizing; and Inspection.
• Cycle Time Reduction Principles and Techniques such as Workpiece Loading/Unloading; Program Execution; Tool Maintenance Time; and Preventative/Corrective Maintenance.  

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 a 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.
