New version for 5-axis gear milling

New version for 5-axis gear milling

GWJ Technology GmbH, calculation specialist from Braunschweig, Germany, presents a new version of its special gearing software GearEngineer.

GearEngineer is a special gearing software that calculates the exact and real 3D tooth form geometries of cylindrical and bevel gears. The 3D tooth forms are generated by means of mathematical manufacturing simulations. Micro-geometries, i.e. profile and flank modifications, are also taken into account when generating the 3D data. This makes GearEngineer the ideal starting point for 5-axis gear milling.

With the new version, GearEngineer is now 64bit and adapted for WIN 10. At the same time, the internal CAD core has been updated and, in addition to the surface and curve output, provides even more stable 3D solid models with special functionalities such as the circumferential chamfer for cylindrical gears.

The definition of the tool reference profile for hobs has been supplemented by the new "full radius" head shape in addition to the "radius with straight line" head shape. This makes it possible to calculate and produce cylindrical gears with a full root fillet. For cylindrical gears, the load capacity methods according to DIN 3990, ISO 6336 and ANSI/AGMA 2001 were supplemented by VDI 2736 for plastic gears. In addition, plastics have been included in the material database. Another new feature is the possibility of calculating spur gear pairs with an "incorrect" centre distance. For this purpose, a corresponding function has been integrated in the design of the profile shift factors.

In addition, the module for spur and helical bevel gears has been expanded to include profile modifications in addition to the existing flank modifications. Thus, crowning and tip relief as well as pressure angle modifications are now available for each flank. In addition, the "duplex" bevel shape is now supported, which results in a constant tooth root along the tooth width. This extension together with the profile modifications was added, among other things, due to user requests from the field of forging differential bevel gears.

In addition to the output options of CAD data in STEP and IGES format, so-called nominal measurement data are also possible. Here, an updated version of the KIMoS format of the Klingelnberg software of the same name was integrated, which supports the measurement of the flank topography on corresponding gear measuring centres or 3D coordinate measuring machines.
