INVESTIGATION OF TOOL LIFE IN AL / SIC COMPOSITE MATERIAL WITH ULTRASONIC WAVES MACHINING

The machining process is one of the most widely used methods in manufacturing metal parts. The most important issues of machining are the life of the tool. The life of the tool ,in turn, is influenced by the regulatory process parameters. The life of the tool represents the useful life of the tool, which is expressed in terms of the time from the moment of the beginning of the cut to the ending point which is determined from the day of the standard of disability. The parameters of this process have different effects on the abrasion of the tools. Therefore, one of the problems that are mixed with this process is the choice of optimal parameters to achieve the most favorable abrasion tool. The main objective of this study was to investigate the effective parameters of machining (cutting speed, feed speed and cutting depth) on the life of a titanium nitride-coated steel thinner tool on an ultrasonic perforation drilled AL / SIC composite material... In order to collect the experimental data, the Taguchi design was used in the design of the experiments. Then, with the help of ANOVA, the parameters levels are determined in order to maximize the life of the tool. The results showed that cutting velocity, cutting rate and cutting depth increased tool wear and reduced tool life in the AL / SIC material.
