ESTIMATION OF CUTTING FORCES BY REGRESSION ANALYSIS IN MACHINING OF AL-SIC MMCS

The increasing usage of MMCs in aviation industries is due to the excellent properties of the MMC materials which helps in sustaining the properties for longer period of time. In this regard, an attempt is made to evaluate the properties of the composite material reinforced with silicon carbide particles. The motto of writing this technical paper is to analyze the impact of machining parameters with respect to the hardness of the materials which gets altered due to cryogenic treatment. The study is focused on analyzing the cutting forces that are generated during machining of normal and cryotreated materials for varying speed, feed and depth of cut parameter. Mathematical modeling represents the behaviour of a system using mathematical concepts. A mathematical model helps in prediction of behaviour of a system under circumstances which have not been physically observed. A Mathematical model is developed by using the concepts of mathematics which helps in analyzing the effects of various parameters and to make predictions about the behaviour of the system. The models generated are usually based on variables and the relationships. Variables are the parameters of interest that can be quantified and Relationships are described as differential operators, functions or algebraic operators etc..
