In the process of machining rectangular microchannels, severe friction occurs between the chip and the sideface of the machined microchannel. The cutting forces have great effect on the miniature cutting tool. Thus, 3D FEM isadopted to study the cutting forces. The influences of the depth of the machined microchannel t , the cutting depth a c , thecutting width a w , the rake angle ○ o and the cutting speed ν on the cutting forces are investigated. Results show that the main cutting force F z and the thrust force F y increase with the increase of t , a c and a w and have no obvious change with ν.Moreover, F z decreases and F y increases as γ○ increases.
