| Popis: |
A method for determining the most dangerous zones of the hob cutter to develop the fastest wear of teeth and edges by the criterion of maximum friction on the contact surfaces has been developed. The geometric model of 3D undeformed chips, which is the basis for determining the force and tribological load, considers the actual shape of the transition surface in each gap, considering the shape and size of the inner surface of the chips, which is formed during the previous axial position of the hob. The cutting force was investigated as a function of the cross-sectional area and the chip compression ratio. This value is set depending on the variable thickness of the cross-sections and is determined using the Deform 2D software. The effect of changing the actual geometry of the cutting wedge of the hob’s teeth on friction and contact conditions on the flank face of the trailing edges ultimately determines the maximum wear of the hob cutter. |
