The focus of this study is to optimise the design of a milling machine control knob which is found to be difficult to operate. The independent variables include body positions, arm positions, finger positions, torque direction and tactile sensation. The size of the finger is also taken into account for designing the knob. The early study includes the feedbacks and data collections directly from the industrial manual workers from 8 manufacturing firms on the preference of body positions, arm positions, finger positions and the designs of knobs. The collected data were analysed via multiple regression analysis using Minitab 16 statistical software and narrowed down into three levels per variable. A number of shapes were selected based on literatures and this amount was reduced to one shape (knurled spherical knob) based on the survey and observational studies.
