document: Generic simulation approach for multi-axis machining . Part 2 : model calibration and feed rate scheduling For Part 1 see ibid . vol .124 -LRB- 2002 -RRB- . This is the second part of a two-part paper presenting a new methodology for analytically simulating multi-axis machining of complex sculptured surfaces . The first section of this paper offers a detailed explanation of the model calibration procedure . A new methodology is presented for accurately determining the cutting force coefficients for multi-axis machining . The force model presented in Part 1 is reformulated so that the cutting force coefficients account for the effects of feed rate , cutting speed , and a complex cutting edge design . Experimental results are presented for the calibration procedure . Model verification tests were conducted with these cutting force coefficients . These tests demonstrate that the predicted forces are within 5 % of experimentally measured forces . Simulated results are also shown for predicting dynamic cutting forces and static/dynamic tool deflection . The second section of the paper discusses how the modeling methodology can be applied for feed rate scheduling in an industrial application . A case study for process optimization of machining an airfoil-like surface is used for demonstration . Based on the predicted instantaneous chip load and/or a specified force constraint , the feed rate scheduling is utilized to increase the metal removal rate . The feed rate scheduling implementation results in a 30 % reduction in machining time for the airfoil-like surface
