Static and dynamic analysis of key structural components of the machine tool is the crucial
stage in transferring the physical to the virtual domain for digital manufacturing trends. The …

The precision of machine tools is essentially determined by the feed drive control. To
improve the dynamic behavior of elastic feed drives, this paper presents a novel position …

The dynamics of the ball screw feed system is very important in high-precision machining of
CNC machine tools. However, the existing literatures rarely study the dynamic behaviors of …

Owing to the geometric errors, preload of ball screws usually exhibits a two-stage degrading
characteristic during operation, which is taken as the running-in stage (the first stage) and …

Owing to the measurement difficulty and the required time needed to analyze wear
processes of ball screws, very few studies have been reported. Here, on the basis of a test …

Ball screws made of SCM445H, NF42CD4 and SAE4150 steel grades were treated by
ultrasonic nanocrystal surface modification (UNSM) technique to boost their performance by …

Passive vibration control of the parallel machine tool is challenging due to its closely spaced
vibration modes and position-dependent dynamics. Owing to the advantages of significant …

Industrial robotics is a continuously developing domain, as industrial robots have
demonstrated to possess benefits with regard to robotic automation solutions in the …

In this paper, a nine degree-of-freedom dynamic model of the ball screw feed system
considering the contact nonlinearity between balls and raceways is established to analyze …

The development of accurate dynamic stiffness models is a key aspect in the design process
of ball screws. However, variations in the nut center of mass position can affect the dynamic …
