From fig. 1 & 2, it can be observed the Upper arm, Lower arm and wrist of the workers posture and by selecting the related position of the model in the worksheet of the database of REBA the score of „5‟ has obtained. While working the shoulder get raised and arm get abducted so the final score of upper arm is „3‟. In the same way for lower arm, by selecting the model score of „2‟ has been obtained and as the arm is working across midline of the body and while working worker has to move the arm out to the side of the body, it will get grand score of the lower arm is „2‟. While working the wrist bent from the midline machining can be any type, here it is of continuous type so for this type of machining some of the time wrist has to be bend so the wrist twist position score is „2‟. After getting these three scores, to find score of posture B, table B has to be used in that the upper arm score „3‟ and in that lower arm score „2‟ wrist position score „2‟ has to be observed this will give the score „5‟ for posture B which will be further get added to coupling score for final score of Posture B. Coupling score of „1‟ has been found as the posture there is mainly static and the Machining action is repetitive. And the load of Machining wheel is of around 4 kg and is again static and repetitive so it gives the score of „1‟.After this score of posture B „1‟ is added to Upper arm, Lower arm and wrist and coupling the grand score of Posture B is „6
