Abstract - Process modeling and optimization are two important issues in product manufacturing. Selecting the optimum cutting parameters, such as depth of cut, feed rate and spindle speed, is a very important issue for any machining process. In shop practice, the cutting parameters are selected from specialized manual or machining databases, but the range provided in these sources are actually initial values and are not optimal values. The optimization of the processing parameters not only increases the utility for the processing economy, but also the product quality to a large extent. Al 7075 aluminum alloy of 7000 series aluminum alloys can be used in a variety of applications. The lightness and hardness characteristics of grade 7075 are highly appreciated by manufacturers and end users. This article shows an analysis and a comparative study of the contribution of processing parameters, i.e. MMR and MT, towards quality characteristics through the use of experimental design techniques.
