Some problems related to contact pressure in slide way joints

Slide ways are presented as a crucial component affecting machining accuracy. The design requirements imposed on the guide joints are discussed. The effect of contact deformability and inherent deformations of particular components of the slide way system on non-uniformity of contact pressure at the slide ways and on displacements of the guide is analyzed in detail. It is shown that the relevant design procedure should account for inherent deformations of components as well as local deformations of contact zones and of screw joints of guiding fences.
