A theoretical model of the mechanical driving system and a dynamic friction force model for the guideway have been developed. The static and dynamic friction coefficients, the relationship between the viscous damping coefficient and the feed speed as well as other valuable results have been found by a series of experiments conducted on a CNC milling machine. It is shown that the actual dynamic friction force model coincides pretty well with the theoretical one.

The contacting friction between glass fibres and steel was analysed based on the common charactor that coupting friction is eff??ted by psessure and stiding speed and kine??atic be?vion, and the f?owing conclusion has been reached, the static friction f?tor between staintess steel (surface finish:?6) and glass fibres with bright and clean surface (μ=0.25~0.30) is targer than the dynamic friction factor (0.22~0.30) and the difference will become even larger if a layer of dry sizing membrance is applied on the surface of glass fibre. The static friction factor will show a maximum value when the stiding speed of fibre glass is near 54.6 cm/s.
