Course Description

Includes developing and practicing mechanical assembly skills on a term-long project using an electro-mechanical device of intermediate complexity. Requires the use of mechanical illustrative drawings and schematic diagrams to create a logical order of operations to efficiently disassemble and reassemble the device. Introduces basic operation of the device for the purpose of testing its proper electro-mechanical operation after reassembly. Prerequisites: MT 151. Audit available.

Addendum to Course Description

For the first run of this course, the project used is a 3D Printer kit.

Intended Outcomes for the course

Upon completion of the course students should be able to:

1. Interpret and articulate the information given on mechanical schematic diagrams.

2. Create a strategy to develop an order of operations to disassemble and reassemble a complete electro-mechanical assembly.

3. Precisely follow procedures, specifications, and checklists to properly complete equipment repair, disassembly, and reassembly.

4. Modify and improve procedures, specifications, and checklists following industry standards and professional technical writing practices.

5. Recognize the appearance and operation of a properly assembled system and quickly define the discrepancies in an incorrectly assembled or incorrectly operating assembly.

Course Activities and Design

This course is structured in a lecture/lab format.

The course will include a variety of learning activities. The lecture portion of the course will include instructor delivered lectures and demonstrations stressing key topics in the course. In preparation for the lecture portion of the course, students will be expected to complete all reading and homework assignments.
The laboratory portion of the course is intended to enhance skill in the operation of basic mechanical assembly instruments, skills system analysis and troubleshooting, skill in teamwork, and skills in oral and written communication. For each lab experiment the students may have to write a report.

Outcome Assessment Strategies

Assessment of student performance in this course will be conducted in both the lecture and laboratory portions of the course and may be in the form of written and /or practice-based questions.  In-class assessment of communication (using proper terminology to ask questions, explain, and make requests within student groups) will be done both by instructor scoring and lab partner peer evaluations.
