Recently, the 5-axis machining of gears has become increasingly important. This technology enables a flexible production of diverse gear types on a single universal machine with standard tools. In addition to the economic aspects, the focus is on the high quality standards that has to be achieved. This paper deals with hard machining for the finishing of spur gears with the 5-axis InvoMilling™ method developed by Sandvik Coromant. A comparison of the hard and soft machining of a module 5 gear is made. The achievable gear qualities in the profile and flank direction, the achievable surface roughness in the profile direction, the torque applied to the milling spindle during the machining process and the wear of different types of inserts are compared and evaluated. In addition, the hard machining with different insert materials/coatings is carried out. View Full-Text
