Mathematical Modeling of Friction Force in LM Ball Guides
Journal of the Korean Society for Precision Engineering, 2015 Linear motion (LM) ball guides have good accuracy and high efficiency. They are widely applied for precision machinery such as machine tools, semiconductor fabrication machines and robots. However, friction force incurs heat between the balls and grooves. Thermal expansion due to the heat deteriorates stiffness and accuracy of the LM ball guides.
