A Study on the Total Tuning of Feed Drive Systems in NC Machine Tools (3rd Report)

Single Axis Mechanical Parameter Tuning

Abstract

This paper deals with the tuning method of mechanical parameters of the single axis feed drive system in NC machine tools. In this method, tuning map is proposed to support the designers to know what level of the total servo performance is achieved and how to modify the mechanical parameters to fulfill the design targets. In the case study, tuning of the ballscrew design parameters and selection of the servo motor are demonstrated on the machine tools for flexible transfer line and machining center.
