Lathe Tool Geometry 351

Lathe Tool Geometry provides a description of single-point lathe tool angles, detailing the effect these angles have on a cutting operation. Tool angles have a significant impact on a cutting operation, as each angle offers a tradeoff between cutting-edge strength and improved tool service life, among other factors. Cutting tool angles must be optimized to each unique combination of workpiece material, tool material, cutting application, and desired surface finish quality. Improper tool geometry leads to premature tool wear and failure, poor surface finish, and slower speed and feed rates. These factors increase manufacturing costs, create excess waste and scrapped parts, and slow production rates. After taking this course, users will be able to better identify and implement proper tool geometry for lathe cutting processes to improve production efficiency and maximize tool service life.
