What is the purpose of a cutting tool’s geometry?

The purpose of a cutting tool's geometry is primarily to optimize cutting performance. Tool geometry includes aspects such as edge angles, rake angles, clearance angles, and the profile shape of the cutting edge. These characteristics significantly influence how effectively a tool can cut through a material.

An optimized geometry allows for better chip removal, reduced cutting forces, and improved surface finish, ultimately enhancing the overall efficiency of the machining process. When the tool geometry is well-designed for a specific application, it can lead to faster machining speeds and reduced wear on the tool, directly contributing to higher productivity in a manufacturing environment.

Understanding tool geometry also helps machinists adapt tools to different materials and machining conditions, ensuring that they can achieve the best results possible in their operations.
