What is a common effect of excessive cutting speeds?

Excessive cutting speeds typically lead to an increase in heat generated during the machining process. When the cutting speed is too high, friction between the tool and the material being cut generates significant heat. This heat can adversely affect the tool's properties, leading to accelerated tool wear. High temperatures can cause thermal degradation of the tool material, resulting in reduced tool life and performance.

Additionally, excessive heat can negatively impact the workpiece, potentially leading to distortion or warping, further complicating the machining process. Therefore, managing cutting speeds is critical to ensuring an optimal balance between productivity and tool longevity, making the increase in heat and tool wear a commonly recognized effect of operating at excessive cutting speeds.
