1. Basics of Metal Cutting
Metal cutting involves the interaction between a cutting tool and a workpiece, where the tool removes material through shear deformation. Key concepts include:
🔪 Chip Formation: As the cutting tool engages with the workpiece, it generates chips through a combination of plastic deformation and shear failure.
📏 Cutting Forces: Forces acting on the cutting tool include cutting force (FC), feed force (FF), and thrust force (FT), which influence tool wear, surface finish, and machining stability.
📉 Cutting Temperatures: High temperatures are generated at the cutting zone due to friction and deformation, affecting tool life, workpiece material properties, and surface integrity.
