Project Description: Ferrous powder metallurgy is considered a net shape manufacturing process which continues to gain increasing use in production of automotive components. However, the relatively poor machinability of powder metal (P/M) steels presents significant challenges to parts producers. This lower machinability, relative to cast parts is largely due to the high level of porosity present in P/M steels as well as the presence of hard metal carbides that often are incorporated in the P/M steels to increase wear resistance of the part. In addition, P/M FC-0208 and P/M FN-0205 blocks with different densities will have different amounts of pores in the block which can affect machinability of the block. This project will involve two machining operations – the first is an end-milling machining operation of P/M steel FC-0208 and P/M FN-0205 blocks at three different densities which will be completed using a machining method developed previously. The second machining operation will involve drilling of P/M FC-0208 and P/M FN-0205 blocks with established conditions. These two machining operations will be used to provide insight into the effects of density and porosity. Metallographic characterization of P/M FC-0208 and P/M FN- 0205 blocks will be completed by the capstone team as part of the project and will provide useful insight into the microstructure of the materials via inclusions, porosity, and non-metallic inclusions in the powder metal. Specifically, the project will involve the following deliverables: a. Complete testing of three (3) different density P/M FC-0208 blocks with triplicate runs for both machining operations. b. Complete testing of three (3) different density P/M FN-0205 blocks with triplicate runs for both machining operations. c. Metallographic characterization of three (3) different density P/M FC-0208 blocks. d. Metallographic characterization of three (3) different density P/M FN-0205 blocks. e. Final report discussing all elements of testing conducted.
