Description of Assignment
Inspiration
Explore how to design, fabricate, and assemble mechanisms by designing and fabricating a mechanical cam toy.
Students will be provided with an example CAM assembly in Fusion 360 that converts rotational input to linear output. Students can modify or build from this example to explore what type of motion, geomtries, and joints can be used to connect and input motion with one or more output movements.
The finished assignment should accomplish the following:
Explore how to connect a rotation motion input (or another motion of their choosing ) to the desired output motion through a series of components using the basic kinematic joints.
Generate aesthetic components to add character to your design.
Fabricate a series of parts that can be assembled into a mechanism- using a combination of cardboard/ paper prototying, subtractive fab (laser cutter) and/ or additive fab (3D printer)
Learn the basics of how to digitally design and assemble mechanisms using Fusion 360.
Learn how to explore mechanism tolerances for additive and/or subtractive fabrication.
