Tapered end mills are useful cutter for machining of inclined surface, for example side surface of mold and die. But there are a number of unclarified points regarding to cutting mechanism of tapered end mills. This paper therefore tries to clarify the cutting mechanism of tapered end mills and aims at presenting basic data on tool design and effective method for using the tools. The main results are as follows. (1) The cutting edge shape and cutting process by chip areas are analyzed geometrically for tapered end mills, and calculating method of the chip areas is shown. (2) Cutting patterns are classified into two types and chip areas for various cutting conditions are calculated. (3) The basic behavior of chip areas by tapered end mills are similar to that by square end mills. But chip areas increase by almost constant ratios in the middle part of cutting process by square end mills in case of type I. (4) Incremental rates of the chip areas in the middle part become large with increase of taper angles and decrease of helix angles.
