Metal Cutting Theory

Metal cutting theory explains how a tool shapes metal by removing material in a controlled process. When a cutting tool engages with metal, it shears off small chips, transforming solid stock into a finished part. Factors like tool shape, cutting speed, force, and temperature influence how efficiently and accurately this removal occurs. Understanding these principles helps optimize manufacturing processes—ensuring quality, reducing wear, and minimizing energy use—by controlling how the tool interacts with the metal during machining.
