Optimisation of Parameters When Polishing Aluminium Cookware Using Wool Felt Wheel

Aluminium is used a used material in houseware (e.g. cookwares, kettles, sinks, etc.). Often rusted, tarnished after a period of use; especially in hot, humid environments. It will lose the beauty and clean of the product. For that reasons, polishing aluminium to a required roughness surface is necessary before using. An experimental study showed that roughness surface is correlated with factors: Velocity, friction force, time, polishing material, workpiece material. Experimental also shows that to decrease the surface roughness quickly if the velocity and friction force are increased but will happen oscillator, lots of power loss; If the friction force and time are increased, it will generate heat, burn marks in the polishing material, the surface will turn orange, not productive. So, to achieve the optimal surface roughness, it is necessary to optimize the above coefficients. This paper presents optimization of coefficient of friction force and time, (F, t) pair with fixed velocity v = 22 m/s for minimization of surface roughness.
