This module presents the concept of tribology, lubrication and surface roughness in the machining process. You will learn how machining with wear tool will enhance the forces, the types of lubrication and surface roughness in machining and the parameters required for calculating the material removal rate in the machining process.

This module presents the concept of tool wear and tool life in the machining process. You will learn about the mechanisms of tool wear and how various work piece materials and application techniques of cutting fluids, affect the tool life in the machining process.
