Abstract
The objective of this research is to use an analytical and experimental approach to develop new trends of cutting tool geometry with negative Side Cutting Edge Angle (SCEA). The first task of this research is to conduct experimental tests for different SCEAs, cutting speeds, feed rates and depths of cut. This is accomplished as follows. One set of these experimental results will be used as a feedback to develop new empirical formulae required to predict cutting forces and other machining parameters. A second set of experimental tests will be conducted in this study to ensure the validity of the empirical relationships associated with the mathematical model. The second task is to develop a mathematical model to predict cutting forces for the three dimensional oblique cutting operation. New cutting tools will be proposed by using the results of the expanded mathematical model.
