Abstract
In this study, the axis compositions of five-axis machining centers (MCs) are collected through websites and catalogues. The analysed 5-axis MCs are divided into three types. The deviations of the axes motion are discussed. Telescoping magnetic ball bar (TMBB) is applied in the measurement method of the effectiveness of deviations. The proposed procedure of ball-bar setting is evaluated for general structural codes of all types according to the simultaneous motion of four and five axes. They are simulated using software of dynamic analysis and design system (DADS). The influence of deviations in the measurement method is discussed. The results show that the geometric deviations can be estimated by the proposed method. The simultaneous motion of five axes using a simple jig is proposed as an alternative method of measurement. It is found that the proposed method is effective to evaluate the geometric deviations in simultaneous five-axis motion as well in simultaneous four-axis motion.
