ANALYSIS OF MACHINE TOOL FEEDING SYSTEM TRIBOLOGICAL CHARACTERISTICS AND RESEARCH ON IMPROVEMENT MEASURES

Abstract

Abstract: On the basis of establishing the dynamic model of machine tool feeding systems, the main reason which leads to cause the vibration of feeding systems with different tribological characteristics is analyzed. In order to solve the vibration problem in ultra-precision feeding systems the two grade feed strategy is presented to raise synthesis rigidity and guide soft band is adopted to improve the relation between tribological coefficient and velocity. Finally, the results of experiments show that high control precision about 10 nm can be gotten by using the improved measure when the feeding force is 5 000 N.

Key words: Improvement measure, Machine tool, Tribological characteristics, Vibration
