The Effect of Drawbar Force on Metal Removal Rate in Milling

Model-based chatter stability prediction for high-speed spindles

“…They show that spindle dynamics depend on a large number of factors, including holder characteristics [8], spindle shaft geometry and drawbar force [9] and the stiffness and damping provided by the bearings. Most of these factors are independent of the spindle speed, but bearing stiffness depends on changes in load and spindle speed.…”

Ultrasonic measurement of contact stiffness and pressure distribution on spindle–holder taper interfaces

“…Static stiffness was also measured by applying a load at the tip of the holder or a simulated tool, and measuring the corresponding deformation [1,18,19]. Xu et al [1] measured the axial and radial stiffness with different clamping forces using a home-made platform.…”

“…With the above theoretical and experimental methods for the spindle-holder interface, the effects of clamping force on the contact characteristics of taper interface have been extensively studied [1,2,[7][8][9][10][11][12]18]. In contrast, few researches focused on the angle fitting error of taper joint, although it has an important influence.…”

Modeling of Self‐Vibratory Drilling Head‐Spindle System for Predictions of Bearings Lifespan

“…Many authors have investigated the dynamic behaviour of machine tool spindle-bearing systems, both analytically and experimentally. They show that spindle dynamics are influenced by a large number of factors, including holder characteristics [4], spindle shaft geometry and drawbar force [5,6], and the stiffness and damping provided by the bearings [7]. Most of these factors are independent of spindle speed, contrary to bearing properties [8,9] and the spindle rotor dynamics, which change according to spindle speed.…”
