This article is to research the factors to the lifespan of the carbide coated cutters. We use the face Milling Cutter as an example and the parameters are the cutting speed, federate, cutting depth, and cutting height. The result shows that the main factor to reduce the cutter abrasion is the federate. The higher the cutting speed is, the higher the cutter abrasion. Also deeper cutting depth causes more cutter abrasion, but this effect is not as much. This research applies the Process Optimization of matter element, relational function etc. maximizing the lifespan of Face Milling Cutters.
