Background: Bottom bracket (BB) shells (figures 1 and 2) are a key component of bike frames and are relatively easy to make, depending on the base material aluminum is very easy to machine, but other materials such as titanium (strong and light) or stainless steel (durable) are very hard to machine (takes more time). Titanium Threaded, 1.500" OD: Choose Texture or No Texture 1. BB Shell from Paragon Machine Works Material Titanium Stainless Steel Add to Cart Magnesium Aluminum 2. BB Shell in Bike Frame Assignment: Determine differences in machining (turning) requirements calculate RPM, Feed Rate, Power Consumption, and Turning Time for the component shown in figure 3 (L = 98mm, ID = 47mm, OD = 54mm). Assume 1 mm max depth of cut and a finish pass of .25mm at 75% of the roughing feed rate and starting stock of 2.25in OD and 1.75in ID. Use the spreadsheet developed in part 1: Table 1.
