What is the definition of "tool life" in the context of milling operations?

In milling operations, "tool life" is defined as the duration a cutting tool can effectively perform its intended function before it needs to be replaced. This measure is crucial in manufacturing because it directly impacts productivity, cost efficiency, and quality of the finished product. A tool that has a longer effective life reduces the frequency of replacements and interruptions in the machining process, allowing for smoother and more efficient operations.

Understanding tool life helps machinists optimize their processes. They can schedule tool changes to minimize downtime and select tools that provide the best performance based on material, cutting conditions, and desired results. This definition emphasizes the importance of maintaining a balance between tool longevity and machining efficiency, ensuring that tools do not wear out prematurely or lead to inadequate cutting performance.
