CAD I - Reverse Engineering Small Appliances

Students in CAD I participated in an extensive lesson on Reverse Engineering.  In this activity students will bring something in from home, such as a small appliance, toy or fixture.  With this they will disassemble and dissect each item, learn what it does and conclude how the object works.  They will learn how to use basic hand tools & how and why parts are engineered, while looking at the Principles of Design and learning about a variety of materials used in industry.  Students will also learn how to keep an engineering notebook as they document and describe the parts of their particular appliance.

CAD II - Small Gas Engines; Reverse Engineering

This invaluable experience is always a favorite of all!!  Students in CAD II learned all about hand tools, mechanical fasteners and how engines operate, including understanding the 4-stroke and 2-stroke cycles.  The students applied their knowledge to completely disassemble the engines using basic and specialty tools needed to remove a variety of fasteners they previously learned about.  Students also gained knowledge of the major engine operating systems including lubrication, cooling, electrical, fuel and governing.   Different materials (steel,aluminum, cast iron) were also explored along with troubleshooting and service methods.
