The InvoMilling process, a unique approach to milling spur and helical gears using indexable insert cutters was front and center during Gear Expo. InvoMilling opens up new, cost-efficient ways to produce geared components without dedicated hobbing machines. Since complete components can now be machined with just one set-up in a single five-axis machine, overall production lead-times can be reduced dramatically as waiting for expensive hob cutters is not required. One InvoMilling cutter is capable of producing multiple module or DP sizes. Also, eliminating a hobbing operation dramatically shortens the value stream and overall work in process. And the new generation of indexable carbide insert gear cutters will increase cutting data and lower the cost per machined gear wheel. The milling process was being demonstrated on a DMG/Mori Seiki NLX2500SY machine at Rave Gears booth (# 951) during Gear Expo.
