Surface location error for helical mills [PDF]
, 2006 Stability and surface location error are investigated numerically for milling operations with a helical tool. A detailed mechanical model is derived that includes both surface regeneration and the helical teeth of the tool. The governing delay-differential equation is analyzed by a modified version of the semi-discretization method.
