MCH 227 – CNC Grinder Operation consists of the following modules:

CNC Grinder Machine Panel - 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 Grinder 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 Grinder Key Sequences - In this module the student is introduced to the Key Sequences of CNC machine operation for Machining 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.  

PREREQUISITE SKILLS AND KNOWLEDGE:  
MCH 226  

 The student will be able to understand and demonstrate the proper setups, uses and operations associated with the Horizontal CNC Surface Grinding machine and its accessory devices.  

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:

• Functions of the Buttons, Switches and Keys found on CNC Grinder Machine Control Unit (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.
• The five CNC Grinder Modes of Operation; Manual; Manual data Input (MDI); Edit; Program Operation - Memory (Automatic) & Tape.
• Key Sequences of CNC machine operation for the CNC Grinder.
• CNC Program Verification such as: Safety Priorities; Running Good Parts; and Verification of Programs.  

 
MCH 226 - CNC Grinder Programming will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.  

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.
