ABSTRACT
Dynamic situations are not fully controlled and affected by uncertain human factors. Anthropometric considerations are significant in the design of industrial systems. Present research work has considered the 'viewing angle', whose effect on operator's performance has been ergonomically evaluated in a CNC-EDM environment. In this work, the experimental data is analyzed through an ANOV A using SPSS statistical software. The result indicates that the viewing angle significantly affects the operator's performance in a CNC-EDM interaction environment. Fmiher analysis revealed that a 21 degree viewing angle gives the optimal performance as far as a Human-CNC machine interaction environment is concerned.
