GENERAL TECHNICAL INFORMATION RELIEF GRIND AND TOOL FLANK DESIGN 2 types of relief grinding: linear relief angle 1. 2-chamfered linear relief grinding with primary and secondary flute. 2. Radial relief grinding The 2-chamfered surface relief grinding is the most common and easy to measure or to determine by the size of the relief angle. The radial relief angle can be clearly indicated only over a determined measuring length, but the convex shape that reduces the angle, has to be taken into account also. This kind of grinding can offer considerable advantages, for example if regrinding shall only be carried out on the rake face. 1. Milling performance and tool life of the cutter are very much influenced by the primary relief angle of the flutes. The primary relief angle depends radial relief angle on the application of the cutter (workpiece material etc.) as well as the suitable feed rate of the respective diameter. This is important especially for regrinding, because the performance of standard tools can thus be optimized. W = Radial flute width LW = Radial land width PRa = Radial primary relief angle SRa = Radial secondary relief angle Ra = Radial rake angle 2. 461
