The cutting speed in the datasheet of a cutter is often calculated for a service time ("Standzeit") of 1 hour. That means if you mill with the exact parameters that are posted in the datasheet, the cutter will be unuseable after about one hour. | The cutting speed in the datasheet of a cutter is often calculated for a service time ("Standzeit") of 1 hour.

=== Milling Strategy === | |||
Or: conventional milling vs climb milling. There are two ways of cutting material: either the spindle direction is the same as the feed or not. The first method is called climb milling or in German Gleichlauffräsen, where the latter one is called conventional milling or in German Gegenlauffräsen. | |||
As our feedspindles have some backlash, we can not really make use of climb milling on our machine! Of course, you can use climb milling for finnishing passes, if you remove very less material. In all other cases use conventional milling. | |||
If you mill with the full cutter diameter, there is no difference of the feed direction though, as half the cutter is in climb mode, the other half is in conventional mode. | |||
If you are milling outer contours you have to go clockwise, on inner contours you need to go counter-clockwise. | |||
