Note: I dropped this class due to medical reasons. A large chunk of the mechanical design work is shown in the table below, but unfortunately I was unable to complete the physical build.
2.70: Precision Product Design
|
This class teaches the fundaments of precision product design, with an emphasis on optimizing accuracy, repeatability, and precision through an iterative analysis approach. We learn the physics and mechanics that apply to each of the topics (linkages, power transmission, screws and gears, actuators, structures, joints, bearings, error apportionment, and error budgeting), and how to apply them to analysis and machine design decisions.
The semester-long project is a one-to-three axis machine of our choice. I chose to design an fused filament fabrication (FFF) 3D printer. Instead of the traditional orthogonal 3-axis layout, I am pursuing the delta linear design, which (aside from having fascinating kinematics) means that I only have to design three identical axes. My progress throughout the semester can be seen in the links in the table below. Most of the design documentation is under the "Practical Uploadable Psets" column. |
