The process has then more the function of a roughing process to reduce the tool wear of the roughing tools in 4- or 5-axis milling. Theoretically, this pre-machining should also reduce the necessary cutting time for the following 4-axis milling process, but it makes programming and processing much more complicated, so this is not very common.

Consider a toolchange between roughing and finishing. Instead of using the largest tool that fits the smallest radius of the tool path, use an even larger tool for roughing and let the finishing pass deal with the smaller radii. Roughing is where you're hogging the deep chatter-prone cuts anyway. Never use a longer tool than necessary.

The finishing process is used to get a high quality shape of the gear and to get low surface roughness. To get low cutting forces in the finishing step, the mate- rial stock after the roughing process has to be minimized. A low amount of stock on the flank offers the possibility to use high cutting speeds.
