Machinability Investigations on Al6063+TiO2 Metal Matrix Material
Abstract
Investigations into the machinability of Al6063 alloy reinforced with TiO2 particles typically focus on understanding how the addition of TiO2 affects the machining characteristics of the metal matrix material compared to the base Al6063 alloy. Here are some aspects that such studies would typically explore: Tool Wear, cutting forces, Material removal rate, surface roughness. These investigations are crucial for understanding how the addition of TiO2 particles modifies the machinability of Al6063 alloy and for optimizing machining processes to ensure efficient production of components with desirable mechanical and surface properties.

Introduction
Aluminium alloy 6063, often referred to simply as Al6063, is a popular metal matrix alloy known for its excellent combination of mechanical properties and workability. Al6063 primarily consists of aluminium (Al) as the base metal, with significant additions of magnesium (Mg) and silicon (Si). Typical composition ranges are approximately: Al: 97.0 - 98.5%, Mg: 0.45 - 0.9%, Si: 0.2 - 0.6%.
Other trace elements like iron (Fe), titanium (Ti), Zinc (Zn) and chromium (Cr) in small amounts.
Conclusion
The following conclusions are drawn from the work carried out
• The maximum material removal rate observed is 13.27 gm/min for trail-5 in case of TiO2(2%), for the machining parameters s = 445 rpm, f = 0.21 mm, d =0.2mm, at r= 200 and corresponding cutting force is 25.079 kgf.
• The maximum material removal rate observed is 14.975 gm/min for trial-8 in case of TiO2(6%), where the machining parameters are s = 445 rpm, f = 0.421 mm, mm, d =0.5mm, at r= 20° and corresponding cutting force is 14.566 kgf.
• From the graphs it is evident that in case of machining Al6063 with TiO2 (2%) increase in speed and rake leads to higher MRR whereas for depth of cut and feed shows decline trend.
.• Resultant in case of machining Al6063 with TiO2 (2%) is increasing for increase in depth of cut and rake angle, however it has down trend in case of increase in speed and feed.
• Al6063 with TiO2 (6%) machining has uptrend behaviour of MRR with all input parameters
• While machining Al6063 with TiO2 (6%) resultant for has uptrend with depth of cut and feed but has downtrend with speed and rake angle.
