This paper presents a novel learning control method for ball-screw-driven stages. In recent years, many types of friction models that are based on complicated equations have been studied. However, it ...

Provides generic threading support and specialized support for standard triangular (UTS/ISO) threading, trapezoidal threading (ACME), pipe threading, buttress threading, square threading and ball ...

Ball-screw drives are one of the common wear parts in machine tools. The wear will affect the positioning accuracy of motion axes and can cause a high rejection rate in production. Therefore, it is ...
