COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

Students will be able to check dimensions using:

1. Rulers and Scales in both inch and metric standard.

2. Standard, Digital, and Electronic Laser Micrometers in both inch and

Metric standard.

3. Vernieres in both inch and metric standard.

4. Height Gauges: Standard, Dial, Digital, and Electronic.

5. Optical Comparator.

Students will be able to describe the application and operation of

Coordinate Measuring Machines (CMM) and Non-Contact measuring tools

Topics and Scope

1.  Dimensioning and Tolerancing notes gauging with measurement tools ö

calipers and micrometers.

2.  Units of measurements system international (S.I. Metric) and U.S.

customary linear units using the vernier scale principles.

3.  Dimensions representations on drawings, calculations to describe

degrees (angular units) utilizing sine bars and optical comparators.

4.  Cartesian principles ö coordinate dimensions incremental and

absolute

5.  Coordinate measuring machines (C.M.M.) types and sizes.

Relationships to vernier principles, micrometers, and height gages.

Assignments:

Students will:

1.  Read and study assigned chapters from the A.S.M.E. Standard 1994 and

understand the procedures for measurements with various tools.

2.  Be tested on assigned readings, symbols, dimensions, and features of

coordinate measurements made with metrology tools and features and

be assigned drawings.

3.  Select and visit various sites using C.M.M. practices, observing

methods of inspection (metric and U.S. systems) with C.M.M. machines

and support measurement tools and gages.

4.  Utilize the surface plates to measure angular units and

perpendicularity parallelism with required accuracy in metric and

U.S. systems.

5.  Measure assigned parts from prints to verify correct dimensions with

micrometers, calipers, and comparators.

Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 0%
None
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments and skill demonstrations are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 15 - 20%
Homework problems, Field work, Lab reports, Quizzes, Exams
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 15 - 20%
Class performances, Field work, Performance exams
Exams: All forms of formal testing, other than skill performance exams.		Exams 45 - 55%
Multiple choice, True/false, Matching items, Completion
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 10 - 15%
FIELD AND LAB REPORTS
