Study on tool wear and surface roughness in machining of particulate aluminum metal matrix composite-response surface methodology approach (2010, background): “Manna et al. [ 4 ] investigated the machinability of Al/SiC MMC and found that no built-up edge (BUE) is formed during machining of Al/SiC MMC at high speed and low depth of cut and also observed a better surface finish at high speed with low feed rate and low depth of cut.”
A review on conventional and nonconventional machining of SiC particle-reinforced aluminium matrix composites (2020, background): “Manna and Bhattacharayya [54] conducted a series of experiments and found that the cut- ting force was smaller at lower cutting speeds, whereas the feed force was larger at lower cutting speeds than at higher cutting speeds.”
Machinability issues in turning of Al-SiC (10p) metal matrix composites (2008, background): “– At lower cutting speeds the soft aluminum matrix has a strong tendency to form stable BUEs on the tools surface [ 1 , 2]. – Generally high feed rates are preferred as the high feed rates tend to soften the matrix facilitating easier removal of hard SiC reducing tool wear and increasing surface fin”
