Abstract: | In the milling process, the major flank wear land area (two-dimensional measurement for the wear) of a small-diameter milling
cutter, as wear standard, can reflect actual changes of the wear land of the cutter. By analyzing the wearing characteristics
of the cutter, a cutting force model based on the major flank wear land area is established. Characteristic parameters such
as pressure parameter and friction parameter are calculated by substituting tested data into their corresponding equations.
The cutting force model for the helical milling cutter is validated by experiments. The computational and experimental results
show that the cutting force model is almost consistent with the actual cutting conditions. Thus, the cutting force model established
in the research can provide a theoretical foundation for monitoring the condition of a milling process that uses a small-diameter
helical milling cutter. |
