A Study of Rotary Shaving by Die-Type Cutting Tool
The mechanism of rotary shaving with a die-type annular cutting tool is studied. This machining is a newly developed rotary cutting process and is able to be used very efficiently to shave off the surface of rod material. It is shown by experiments that both the drawing force and the chip thickness decrease sharply with increasing the rotational velocity of tool, as the type of chip formation changes from tear type to flow type. The simple chip formation model of rotary cutting process is introduced on the other hand, and the characteristics of cutting force is investigated. The calculated result well agrees with the experimental result.
