The effects of cryogenic minimum quantity lubrication (CMQL) on cutting forces and cutting temperature are analyzed in high speed milling of 300M steel. The influences of cutting parameters on cutting forces and cutting temperature are predicted by analogue simulation. Based on single-factor comparative test, the variation laws of cutting forces F and cutting temperature T with cutting parameters...
Disturbance observer (DOB) is generally introduced into motion control systems to eliminate undesired disturbances and plant uncertainty. The DOB is also used for system identification. This work presents a novel experimental identification algorithm using disturbance observer to identify inertia, viscous coefficient, and friction of linear-motor-driven motion system. A conventionally adopted algorithm...
