Mathematical modeling of cutting effects on flank and bottom edge of end-milling

<ns3:p>This ongoing study replicates a new mechanistic model for cutting forces in flat-end milling activity. The model considered the total cutting force due to the bottom edge and the flank edge together, which is a unique feature. The model development for flank cutting force coefficients utilizes an exponential function of the instantaneous uncut chip thickness to incorporate size effect for flank cutting in a non-linear least squares algorithm. After the flank cutting force coefficients are calibrated, the instantaneous calibrated coefficients for the bottom cutting force are obtained by calculating the difference between the total measured force and flank force component. This means you can assume the bottom cutting force coefficients are constant values. The cutting force model has been verified through experiments based on different cutting conditions.</ns3:p>
