The feed system is a typical mechatronics system, as well as motion control equipment, that
serves as a fundamental component of CNC machine tools. Develo** a precise …

The accurate stiffness estimation of linear guideway assembly is determined by the
structural deformation of carriage and supporting rail-pedestal-bolt joint. This paper …

For machine tools composed of functional components bonded by joints with structural
nonlinearities, the load-and temperature-dependent nonlinear restoring force, stiffness, and …

The contact properties of the screw-nut pair play a decisive role in the wear rate and service
life of ball screws. The difficulty of the ball contact loads directly detected has resulted in the …

Significant advancements in ultra-precision machining technology have forced a re-
examination of the spindle perpendicularity errors' impact on the milled surface quality at the …

For the asynchronous motorized spindle directly driven by the induction motor, the load-
dependent slip ratio determines that its transient characteristics are sensitive to load. For the …

Load distribution in ball screws is characterized by non-uniformity, leading to imbalances in
the contact load of the balls along the nut. This non-uniformity negatively impacts the …

Most studies on linear rolling guides usually assume the contact load between the ball and
the raceway is uniform, which results in a deviation from the actual conditions. This study …

A comprehensive static load distribution model of double nut ball screw (DNBS) is
presented. The axial, lateral, and torsional deformation of the screw and the geometric error …

Monitoring external disturbing forces is of great significance for improving the control
performance and interaction safety of ball screw drives. In consideration of the low cost in …
