assumed to be a coated carbide tool and 1018 steel. The objective of the simulation was

to validate the MCMC method by comparing its solution to the known force coefficients used to define the “measured” data via the simulation. The parameters used in the down milling simulation are listed in Table 1. The simulation was exercised at different feed per tooth values and the mean forces were recorded; see Table 2. The mean values listed in Table 2 were treated as experimental results and used to update the force coefficients' prior distributions using the MCMC method for Bayesian inference.
