The following parameters must be specified for the calculation and display of an optimized tip outline for bevel and hypoid gears with any root line course of the mating gear:
- Show optimum tip contour: The optimized tip contour is shown in the contact pattern graph in the report, either exactly (i.e., as calculated) or simplified as 3 straight lines.
- Minimum permissible clearance: A minimum permissible clearance can be specified for calculation of the optimized tip contour, where the (theoretical) clearance c is the minimum distance between the tooth tip and the tooth root of the mating gear.
- Specification of the minimum permissible tip thickness or minimum permissible relative tip thickness: The minimum permissible tooth tip thickness to be checked must also be specified, either as an absolute value in mm (minimum permissible tip thickness) or as a multiple of the mean normal module (minimum permissible relative tip thickness). The default value is: minimum permissible relative tip thickness = 0.3.
