Friction plays a significant role in machining processes, primarily influencing wear and surface integrity. When metal is machined, the contact between the cutting tool and the workpiece generates friction. This friction can lead to several detrimental effects, such as increased tool wear, which ultimately reduces the lifespan of tooling. Additionally, excessive friction can result in surface issues on both the machined part and the cutting tool, leading to poor finishes and potentially dimensional inaccuracies.

Understanding the impact of friction is crucial for optimizing machining conditions, such as selecting appropriate cutting speeds, feeds, and coolants to mitigate adverse effects. By managing friction effectively, machinists can improve the efficiency of the process and maintain better control over the quality of both the tool and the finished part.
