Chatter stability analysis in Micro-milling with aerostatic spindle considering speed effect

•Speed-varying dynamic stiffness and damping coefficients of aerostatic bearings are considered.•Effects of centrifugal force and gyroscopic moment due to rotating speed on aerostatic spindle dynamics are analyzed.•A method for calculating the speed-dependent stability lobe diagram (SLD) is proposed...
