Abstract
The performance characteristics and service life of machine tools are influenced by the type and the design features of the guideways used to ensure a predetermined path for the moving parts with The guideways of machine tools are generally used to appropriate accuracy and reliability and to provide adequate rigidity. low frictional behaviour and suitable damping properties Sliding ways have brbeen the traditional means of support in linear motion systems because they can handle heavy loads and provide extremely rigid support However. although they are relatively inexpensive they oftenly can not meet the stringent speed and response requirements of modern machinery These requirements In this thesis the design concept and the are more readily met by rolling friction guideways .characteristics of the two main types of guideways namely slideways and rolling friction guideways are reviewed and discussed The study is directed towards investigating the design problems of the rolling friction guideways nalytical approach is introduced to elaborate the effect of the loading conditions and the design parameters on the performance characteristics of the rolling guideways .
