Point-by-point prediction of cutting force in 3-axis CNC milling machines through voxel framework in digital manufacturing

A new digital-based model is presented for the prediction of cutting forces in 3-axis CNC milling of surfaces. The model uses an algorithm to detect the work-piece/cutter intersection domain automatically for given cutter location, cutter and work-piece geometries. The algorithm uses a voxel-based representation for the workpiece and rasterized tool slice to detect the tool engagement. Furthermore, an analytical approach is used to calculate the...
