Bearing nonlinearity and stability analysis in high speed machining
Article Abstract:
A study is conducted to investigate the behavior of angular contact ball bearings used in high speed spindles. Comparison of analytical and exprimental results show that bearing stiffness decreases as rotational speed increases. Bearing dynamics also affects the natural frequency of the spindle system. Increased rotational speed decreases the natural frequency which in turn affects the stability zones. Stability factors must be considered since these are significant in obtaining high speed machining parameters.

Machining parameter optimization for specified surface conditions
Article Abstract:
A method for determining the machining parameters that will optimize the metal removal rate for a given surface quality and tool life is presented. The surface roughness and residual stress distribution of the surface is used to develop an optimization function that obtains the cutting speed, feed rate and depth of cut that maximizes the production rate while satisfying the surface conditions. The application of the method to examples of rough cutting and fine cutting cases are also described.

Optimization strategies for machine tool spindle-bearing systems: a critical review
Article Abstract:
The spindle-bearing system is a significant factor in determining machine tool performance. The optimization design of spindle bearings involves three aspects which include the effect of geometrical configuration on the static and dynamic properties, the choice and configuration of bearings and the use of addtive damping treatments. Past and present research efforts on the optimization of machine tool spindle bearing systems are compared and evaluated.
