Experimental Verification of Cusp Heights when 3D Milling Rounded Surfaces

The paper deals with the experimental verification of cusp height when finishing an elementary surface by end ball milling. The relationship expressing the effect of the direction of milling cutter motion on cusp heights has been derived from the geometrical interpretation of inclined elementary surface. Experimental verification has been carried out as 3D milling of surface with definite roundness while surface roughness was measured considering normal vectors of tool-workpiece contact. An approach based on process window has been used to evaluate the measured data.
