Portland Community College | Portland, Oregon

MCH 123 consists of the following modules:

• Sheet Metal Mathematics
• Setup and Operation of Sheet Metal Box/Pan Brakes
• Setup and Operation of Sheet Metal Shears
• Setup and Operation of Sheet Metal Roll Forming Machines
• Flat Pattern Å·ÖÞ±­¾öÈü¾º²Âapp_Å·ÖÞ±­×ãÇòÍø-Ͷע|¹ÙÍøment  

This course is based on competency mastery. Each section is assigned to a specific competency. Sections may be independent or dependent on other sections. The following competency profile is based upon industry standards that have been established for this course:

• Given the necessary tools indicated by the operations on a print, the student will produce a work piece to print specifications.   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 operational principles and applications of the manual shear.

  • Mathematical computations of flat pattern development and layout

  • The operational principles and applications of the box/pan brake.

  • The operational principles of sheet metal roll forming machine. 

MCH 123 – Sheet Metal Fabrication will be presented by means of audio-visual presentations, demonstrations, and lab experiences. 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.

POLICY - Student performance measurements are based on typical business/industry performance standards. They are grouped into performance competencies (specific skills) and knowledge competencies (understanding specific subjects). 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. HOME WORK ASSIGNMENTS - Participation in individual or team structured problem exercises. The emphasis will be to provide introduction to the appropriate areas of study presented/discussed during the class and listed in the course syllabus.

3. 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.

4. FINAL ASSESSMENT - A take home examination in the form of multiple choice, true/false, matching, short answer structure that addresses the subject areas presented/discussed during the class and listed in the course content guide.

5. ATTENDANCE at all scheduled class meetings is strongly encouraged and may be considered in the final grade assignment. 

6. The following schedule of weight will apply to the evaluation activities for this course.

Final Examination                                  35%  
Home Work Assignments                      35%  
Laboratory Assignments                        30%
