Processing of powder metallurgy metal matrix composite and performance analysis during machining Available to Purchase

The ability to process the newly developed hybrid composite containing multiple reinforcements is chosen for this study. The understanding of drilling parameters over material specific characteristics of the Aluminum based Hybrid-reinforced Metal Matrix Composites (HMMC) manufactured through sintering route of Metallurgy. Microstructure, Micro-Hardness and abrasion resistance of the HMMC material is studied. The experimental procedure involved drilling of metal matrix composite using Titanium aluminum nitrate coated solid carbide drill. For this analysis various speeds of spindle and feed rates are selected as the drilling parameters for analysis. Output parameters selected were thrust force and torque. Design of experiments method is followed for the selected parameters. Using the outcome of setups, theoretical framework was developed for output parameters. The performance of the drilling was evaluated in terms of damages on the tool in the form of abrasion and quantity of machining operation completed during drilling. From the study, feed rate was observed to be the most significant factor in its ability to affect the values of thrust force and torque in the composite material under study.
