Last week was spent on developing our MCM. We created a CAD model, relevant drawings, gear ratio analysis, bill of materials, and manufacturing plan. Our MCM is a relatively uncomplicated machine to design, but it had to have very good dimensional accuracy. The machine is responsible for dispensing the tape measure; if any measurement was off too much the tape measure would deploy incorrectly.
The gear ratio analysis we did for the MCM was helpful as well. First, we defined a maximum tape measure extension / retraction rate. From there, we worked through different gear sizes and numbers of gearboxes to figure out the required ratio. Eventually, we were able to design a setup that provided the required extension / retraction rate as well as being able to fit within the size restrictions.
