The stick-slip motion is found to occur in machine tool slides under certain conditions which are

• A. at very high feed rates and/or when there is small difference between the coefficients of static and dynamic friction at the slider and guideway interfaces
• B. at very high feed rates and when there is small difference between the coefficients of static and dynamic friction at the headstock spindle and bed of machine tool
• C. at very low feed rates and/or when there is large difference between the coefficients of static and dynamic friction at the slider and guideway interfaces
• D. at very low feed rates and large difference in coefficient of only dynamic friction at headstock spindle and bed of machine tool
