Course Description

Covers instruction and practice in cutting, filing, layout, scribing, use of gage blocks, and utilizing the height gage to accurately layout lines, angles and the location of part features. Introduces the proper use and applications of the hacksaw, scribe, dividers, prick punch, ballpeen hammer, combination square set, and height gage to produce the accurate layout of part features. Prerequisite: MCH 100. Audit available.

Addendum to Course Description

Layout Tools consists of the following modules:
Layout & Hand Tools - The machinist uses one or more hand tools on every work piece he/she makes. Therefore, it is important to know how to use them properly. The student will learn and practice cutting, filing, layout, and scribing; will use a hacksaw, scribe, dividers, prick punch, ball-peen hammer, and combination square set; will use the safety rules that apply to the machine shop in general and to each of these tools.
Gage Blocks - Parts manufactured in the machine shop must be inspected to determine whether they are within specified size limits. Gages are used for this purpose; will introduce the student to use gage blocks.
Height Gage - The machinist works with various angles frequently. Therefore, it is important that the layout be very accurate for those angles. To help in making an accurate angular layout, the machinist will use a height gage, which the student will learn and practice to use.  

Intended Outcomes for the course

The student will be able to finish a part by accurately cutting and filing and drilling; will learn to use gage blocks and an inspection tool; and will learn to transfer print dimensions to a part most accurately with the height gage.

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 activities:  

  • Hacksaw cutting, filing, layout, and scribing. 
  • Using gage blocks for inspection and specified dimension verification.
  • Using the height gage for precision layout on a work piece.

Course Activities and Design

 
MCH 145 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.
