A comparative study of the effect of tool geometry with negative SCEAs on machining parameters

摘要

The objective of this research was to use analytical and experimental approaches to investigate the effects of cutting tool geometry with a negative side cutting edge angle (SCEA) on machining parameters. The first task of this research was to conduct experimental tests for different SCEAs, cutting speeds, feed rates and depths of cut. The second task was to develop a mathematical model to predict cutting forces for the three-dimensional oblique cutting operation. These tasks were accomplished as follows. One set of the experimental results was used as feedback to develop new empirical formulae required to predict cutting forces.
