The area where crater wear occurs is the region on the face of the cutting tool where the chips come into contact. This is the hottest region during the cutting process and is subjected to high-pressure mechanical friction from the chips against the face of the tool.Therefore, crater wear on the face of the tool […]

Flank wear is the most desirable wear mode.Flank wear is a type of abrasive wear caused by the friction between the workpiece material and the back face of the cutting tool. It starts from the cutting edge and gradually progresses downwards. In the initial stages, flank wear may not be visible to the naked eye

Workpiece materials are primarily composed of metals, and in recent years, with the advancement of material technology, many new materials have emerged. When selecting cutting tools for machining, it is essential to understand and differentiate the cutting characteristics of different workpiece materials.According to cutting characteristics, ISO standards classify workpiece materials into several categories. P –

During cutting operations, the relative motion between the tool and the workpiece can be classified into two categories: Primary Motion The primary relative motion between the tool and the workpiece ensures the basic cutting action of removing excess material at a certain speed. Key parameter: Cutting speed (vc) (m/min) Feed Motion The feed motion complements

Basic Conditions for Metal Cutting Relative Motion The relative motion between the tool and the workpiece is a necessary condition for cutting.The cutting motion can be divided into primary motion and feed motion.Primary motion refers to the main relative motion between the tool and the workpiece, ensuring that the tool removes metal at a certain
