Abstract
In the process of machining rectangular microchannels, severe friction occurs between the chip and the side face of the machined microchannel. The cutting forces have great effect on the miniature cutting tool. Thus, 3D FEM is adopted to study the cutting forces. The influences of the depth of the machined microchannel t, the cutting depth ac, the cutting width aw , the rake angle ○o and the cutting speed ν on the cutting forces are investigated. Results show that the main cutting force Fz and the thrust force Fy increase with the increase of t, ac and aw and have no obvious change with ν. Moreover, Fz decreases and Fy increases as γ○ increases.
Keywords: Cutting force, FEM, microchannel.
