Abstract: The requirements of linear guide ways are rising, especially for machine tools which have to meet the demands of high positioning exactness and stick-slip free behavior with low coefficient of friction over a wide range of speed. These requirements can be met by employing different slide way materials, developing new lubricant additives and through improved oil groove design. Unsteady or variation in frictional force leads to jerky motion or stick-slip in machine tool slide ways. In the present investigation an attempt is made to study the efficiency of different oil groove shapes with reference to the stick-slip behavior and frictional properties over a wide range of speed and load (pressure). The results on variation of the coefficient of friction and stick-slip amplitude for groove profiles ogee, rectangular and different groove shapes (Two, X, Z and Dimple) as functions of sliding velocity and load (pressure) on commercial lubricant are presented in this paper.
