Course DescriptionCovers instruction and practice of precision measurement with tools commonly used by the machinist to produce and measure part features. This course introduces the proper use, applications and parts of the outside, inside, and depth micrometers; the vernier caliper; dial indicators; and the dial bore gage commonly used by the machinist to verify and manufacture part features to print specifications. Prerequisites: MCH 100. Audit available.
Addendum to Course Description
Micrometer - Modern machine shop work requires that measurements be accurate within specified dimensions. The basic and most commonly used measuring device is the micrometer. In this module, the student will learn the tool's basic parts and how to measure with the standard micrometer.
Vernier Caliper - Modern machine shop work requires that measurements be accurate within specified dimensions. A commonly used measuring device is the vernier caliper. In this module, the student will learn to measure with the vernier caliper.
Depth Micrometer - How to measure holes accurately is one of the many skills the machinist must learn. There are several different methods and tools that can be used to perform this operation. The depth micrometer is one of these tools. In this module, the student will learn to use the depth micrometer to determine the diameters of holes.
Dial Indicators - The dial indicator is probably the most used and most important instrument in the tooling trade. In this module, the student will learn to use a dial indicator.
Inside Micrometer - Modern machine shop work requires that measurements be accurate within specified dimensions. The basic and most commonly used measuring device for holes larger than 1½ inch is the inside micrometer. In this module, the student will learn to measure with the standard inside micrometer and learn its basic parts.
Intended Outcomes for the course
The student will be able to accurately check tolerance-dimensions of outside and inside measurements using the micrometer, vernier caliper, depth micrometer, dial indicator, and dial bore gage.
Course Activities and Design
MCH 150 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.
This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding by completing the following activities:
- Accurately measure and record the outside diameters of a test piece with the micrometer.
- Accurately measure and record the outside diameters of a test piece with the vernier caliper.
- Accurately measure and record the depth dimensions of a text piece with the depth micrometer.
- Accurately indicate a part on the lathe, and indicate the table and a vise on a milling machine within .001" with the dial indicator.
Course Content (Themes, Concepts, Issues and Skills)
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.
