Center Height Selection of Corner Radius "S" Sharp Corners Feed 2 Radii Sharp corner JS/P 1 • Cutting edge with positive Sharp rake and sharp corners • When a minimum burr Diameter (pip) size is essential • For small feeds 1. A smaller corner radius (r) will reduce the load on • For small diameters or thin walls the workpiece and produce a smaller size burr • For CNCs, multi-spindle 2. At the same time, a large corner radius allows for P JS and screw machines higher feeds and increased tool life Standard Corner Radius "B" Large Corner Radius Medium (standard) Large corner radius • Reinforced corners with corner radius • Standard medium corner size stronger cutting edge • For general applications • For tough applications and and materials interrupted cuts 419 419
