Course Description

A technical elective course in the Associate of Applied Science Degree in the Machine Manufacturing Technology program. Covers part drawings with gears which provide the technician with a complete description of size, shape, feature location, special tolerances, finish treatments, and assembly instructions so that the product can be manufactured, inspected, assembled and tested to exact design specifications. Prerequisite: MCH 215. Audit available.

Addendum to Course Description

Gears - Gears are the most common form of power transmission in industry today, and can be used in a variety of applications. In this module the student will be introduced to various gear types and the terms used to describe or dimension them.
Math for the Dividing Head - Indexing is a method of dividing a work piece into a number of equal divisions. This module will show the student how to calculate ratio & proportion, roots, speeds for gear and pulley systems, spur gears and indexing methods.  
PREREQUISITE SKILLS AND KNOWLEDGE:  
MCH 215  

Intended Outcomes for the course

 
The student will be able to demonstrate an understanding of various types of gears and the terms used to describe or dimension them; and will be able to calculate ratio & proportion, roots, speeds for gear and pulley systems, spur gears and indexing methods.
 
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:
·         The various gear types and the terms used to describe or dimension them.
·         The calculation of ratio & proportion, roots, speeds for gear and pulley systems, spur gears and indexing methods.
·         Given the necessary material, tools and equipment, the student will perform various standard operations on the lathe, milling machine and surface grinder to produce an arbor press to print specifications.  

Course Activities and Design


MCH 221 - Gears 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

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.
