Technical Information Technical Information KM Application Data Kennametal Operating Conditions The KM tooling joint is an extremely rigid and stable system that is specifically designed to supply consistent results. As with any mechanical coupling, KM has limits that, if exceeded, could result in mechanical damage to the joint and/or its components. To help you stay within these limits, Kennametal has established maximum safe tangential loads for each system size. These loads are described as a certain amount of force at the standard “F” and “L1” dimensions for each given system size. F (mm) F and L1 Dimensions (mm) vs. Tangential Loads (N) for KM32TS Chart 1 Example IMPORTANT Information shown on the following charts was developed exclusively for use with KM tooling in static conditions. Do not use for any other tooling system because the results will not apply. To account for cutting force fluctuations in dynamic conditions, a reduction of 20-30% should be applied to the loads shown in charts. Example of Calculation: Where: P = rated tangential load K = empirical coefficient depending on KM system size and the units of measure Given: Dimensions: The KM integral shank boring bar, ordering code KM40TS S32G-MCLNR12 L1 = 90mm (3.543") F = 22mm (0.866") KM32 KM40 K=190200 K=383600 Required: What is maximum permissible tangential load KM50 K=887400 KM63 K=1718000 KM80 K=3085800 P = K P = 383600 = 5095 N n/ (0.8 L1)2 + F2 (0.8 x 90)2 + 222 M38 Kennametal
