Geometry and coating parameters effect on cemented carbide sticks cutting performance used in bevel gear manufacturing

Wear phenomena affecting the coated tool performance in bevel gear manufacturing are still unexploited due to the restricted possibilities to investigate the influence of the extremely complicated cutting kinematics on the chip removal process. In the present paper the cutting process of bevel gear manufacturing was approached by means of two-axis milling. The cutting conditions and the chip formation of the bevel gear hobbing process were sufficiently considered in the applied milling experimental procedure. The coated tools cutting performance results at various cutting speeds and tool substrate and coating surface mechanical treatments is presented. The results extracted, demonstrate the extent of influence of coated tool surface preparation as well as its geometry on the overall tool life.
