Course Description

Covers dimensions, notes, gears, threads and fasteners which provide the technician with a complete description of size, shape, feature location special tolerances, finish treatments, and assembly instructions are included so that the product can be manufactured, inspected, assembled and tested to exact design specifications, and finishes on part drawings. Introduces the various types of dimensions, tolerances, notes, thread forms, representation, and specifications, finish specifications used in industry today to carry out these functions. Prerequisite: MCH 105. Audit available.

Addendum to Course Description

Dimensions & Notes - Dimensions and specific notes provide the technician with a complete description of size, shape, feature location and finish on part drawings. Additional information such as special tolerances, finish treatments, and assembly instructions are also included so that the product can be manufactured, inspected, assembled and tested to exact design specifications. This module will introduce the student to the various types of dimensions, tolerances, notes and finish specifications used in industry today to carry out these functions.
Threads & Keys - Threads and keys are used throughout industry to fasten, locate and transmit power in a multitude of different applications. In this module the student will learn different thread forms, representation, and specifications used in industry today along with other power transmission devices such as keys and splines.

Intended Outcomes for the course

 
The student will be able to demonstrate an understanding of various types of dimensions, tolerances, notes and finishes; will become familiar with different thread forms, representation, and specifications used in industry today; will become familiar with various gear-types 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 areas of print reading:

  • The various types of dimensions, tolerances, notes and finishes.
  • The different thread forms, representation, and specifications used in industry today along with other power transmission devices such as keys and splines.
  • 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.  

Course Activities and Design

MCH 110 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.
