RISThe Effect of Workpiece Hardness and Cutting Speed on the Machinability of AISI H13 Hot Work Die Steel When Using PCBN Tooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When machining hardened steel (≥45 HRC) with polycrystalline cubic boron nitride (PCBN) tooling, the cutting speeds used produce high temperatures in the primary shear zone, which are sufficient ...
