Objectives
To provide the theoretical foundations and methods that will allow future engineers to understand the fundamentals of the chip removal cutting technology process. The topics covered address issues related to the chip formation mechanism, tool geometry, cutting fluids, and tool materials. Finally, the calculation of machining operations will be discussed.
