Course DescriptionCovers the setup, applications and operation of the horizontal spindle/reciprocating table surface grinder to produce parts to extremely close tolerances with improved surface finishes and accuracy. Introduces automatic grinder operation by grinding a block square/parallel and perpendicular by applying the required setups and operational sequencing, and grinding of angular surfaces on a workpiece to print specifications. Also introduces grinding wheels and abrasives, selecting, balancing and mounting the grinding wheel and the methods/machines of surface grinding. Prerequisites: MCH 100. Audit available.
Addendum to Course Description
Surface Grinding Machines & Operations consists of the following modules:
Automatic Grinder Operation - Grinding is an important part of the machine tool trade. Surface grinding permits the production of parts to extremely close tolerances with improved surface finishes and accuracy. In this module the student is introduced to grinding wheels and abrasives, selecting, balancing and mounting the grinding wheel and the methods/machines of surface grinding.
Square a Block - In this module the student is introduced to grinding a block square, parallel and perpendicular by making the required setups and operational sequencing with the horizontal surface grinder.
Grinding Angles - In this module the student is introduced to grinding angular surfaces on a workpiece with the horizontal surface grinder.
PREREQUISITE SKILLS AND KNOWLEDGE:
Intended Outcomes for the course
The student will be able to understand and demonstrate the proper setups, uses and operations associated with the horizontal 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 subject by:
identifying the four methods of surface grinding and state the advantage of each.
- selecting the proper grinding wheel used for the type of work, true and dress a grinding wheel and grind a part to the specifications of a blueprint within +/- .0005.
- selecting the proper grinding wheel used for the type of work, true and dress a grinding wheel and grind a part square to the specifications of a blueprint within +/- .0005.
- selecting the proper grinding wheel used for the type of work, true and dress a grinding wheel and grind angular surfaces to the specifications of a blueprint within +/- .0005.
Course Activities and Design
MCH 225 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.
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.
