Application of mechanistic force models to features of arbitrary geometry at low material removal rate

This paper presents a workpiece discretization method to apply existing cutting force models predict the forces generated during low material removal rate robotic machining operations of features with arbitrary geometry. Two along straight edge which are modelled using this feature shown, chamfer pass on sharp corner and trapezoidal cross section. The measured high-resolution laser profile scanner obtain volume be removed. identified discretized into rectangular sections such that can applied forces. A linear an exponential mechanistic model relate tool immersion feed scanned features. nonlinear show good agreement data, exception occasionally over predicts depending radial depth cut.
