What are the factor affecting tool life?

Tool life is influenced by several factors, including cutting speed, feed rate, and depth of cut, which affect the heat generated during machining. Material properties of both the tool and workpiece, such as hardness and toughness, also play a crucial role. Additionally, cooling methods, tool geometry, and environmental conditions can impact wear rates and overall tool longevity. Proper tool maintenance and selection are essential for optimizing tool life.
