Derive cutting forces
WebCutting Tool Chip Forces are presented as function of Fc and Ft because these can be measured. Dr. M. Medraj Mech 421/6511 lecture 19/14 Cutting Forces Since R = R’ = R’’, we can get the force balance equations: F = Fc sin α+ Ft cos α F = friction force; N = normal to chip force N = Fc cos α-Ft sin α Fc = cutting force; Ft = thrust force WebEffective cutting speed: mm/min: inch/min: v f: Table feed: mm/min: inch/min: z c: Number of effective teeth: pcs: pcs: h ex: Maximum chip thickness: mm: inch: h m: Average chip …
