Abstract

Dynamic situations are not fully controlled and affected by uncertain human factors. Anthropometric considerations are important in the design of systems. Present research work have considered the ‘angle of abduction’, whose effect on operator’s performance has been ergonomically evaluated in a CNC-EDM environment. In this work, the experimental data are analyzed through an ANOVA using SPSS statistical software. The result indicates that the angle of abduction significantly affects the operator’s performance in a CNC-EDM interaction environment. Further analysis revealed that a 45 degree abduction angle gives the optimal performance as far as a human–machine interaction environment is concerned.
