Investigation of Gear Surface Topography and Deviations in Gear Skiving Through Advanced CAD Modelin
The research presented in this paper extends the work done on CAD-based simulation approaches with an investigation of the surface topography of gears produced through gear skiving and the investigation of the cutting tool characteristics on the geometry of the produced gear. The study is complemented with the investigation of the cutting forces required in the machining process.
Helping Electric Vehicle Manufacturers Compete
“It’s competition,” said the American businessman John Mackey, “that forces companies to get out of their complacency.” We are seeing this in the global electric vehicle (EV) markets. Manufacturers must produce lighter and more compact EV transmissions from tough materials such as low-alloy steels—and those that rely on traditional manufacturing processes risk falling behind. Mats Wennmo, Global Automotive Transmission Manager at the metal cutting specialist Sandvik Coromant, explains why gear skiving is crucial for competitive manufacturing.
Gear Skiving—A Step Changing Manufacturing Process Applicable to Multifunctional 5-Axis Machine Tools
The main benefits of performing the gear skiving process on a multifunctional machine tool include smaller manufacturing cells, reduced capital expenditure, and the potential for an increase in dimensional accuracy of components, as the gear form can be generated in the same setup as the majority of other turned/milled features.
Design-optimized gear skiving tools perform better
Skiving is a complex and demanding procedure with no margin for error. Liebherr can use simulations to identify and exploit possible tolerances in the process kinematics in order to extend the tool life. This allows for optimized tools in terms of tool life and cost-effectiveness – without having to compromise on gear quality.
