Terms of cutting procedures; tool life criteria

This document establishes a comprehensive framework for defining and evaluating the operational lifespan of cutting tools used in manufacturing processes. It introduces specific terminology and procedures for determining when a tool has reached the end of its functional utility, focusing on measurable performance criteria. The content outlines methodologies for assessing wear patterns, tool failure modes, and the factors influencing durability during machining operations. By providing standardized guidelines, this text ensures consistency in how tool life is measured and reported across different industrial applications. It addresses variables such as cutting speed, feed rate, and material properties that impact the longevity of cutting edges. The text serves as a reference for engineers and technicians seeking to implement uniform practices for tool management and replacement scheduling. It details the conditions under which tools are considered obsolete and provides a basis for optimizing production efficiency through controlled tool usage. This approach facilitates better communication between machinery operators, maintenance personnel, and production planners regarding tool performance expectations and replacement timelines.
