Influence Ruleson on Natural Frequency and Input Power of Y-axis Feeding System in Horizontal Machining Center
Abstract:
Some horizontal machining center with the structural characteristics of two columns and a vertical shifting worktable, Y-axis feeding system should meet the requirements of large load bearing, high speed, high precision and low energy consumption. The proper selection of design and operating parameters is the key of ensuring accuracy and energy consumption of machine tools. With analyzing the structure and the performance feature of horizontal machining center with double-column vertical shifting worktable, dynamic equation of Y-axis feeding system was established and the rationality of the dynamic model was verified by combining with finite element analysis. The influence rules of design parameters (screw diameter, worktable mass and worktable position) on natural frequency were analyzed. The influence mechanisms of input power during the system operation process were analyzed, calculation model of input power was presented and the influences of design and operating parameters on input power were analyzed. The research results are valuable for high-precision and low-energy consumption Y-axis feeding system designing.
