For evaluating a workstation, energy expenditure plays a vital role as far as the worker’s safety, health, and efficiency of performing the task most effective and efficient manner is concerned. This study has been carried out for finding the energy expenditure by using Energy Expenditure Prediction Program Software. The energy expenditure was determined by observing and recording the activities during the operations on a lathe machine. In this work, the average metabolic energy rate is predicted by knowing the energy expenditure and task duration. The method used in this work is more accurate and feasible and less costly than laboratory techniques such as measurement of oxygen consumption, carbon dioxide production, etc. The technique used in this work provides an objective rate to gauge worker’s fatigue. The study identifies the grade of physical work based on energy expenditure for various activities during the experiment and the activities having higher energy expenditure as compared to set limits by various agencies to be ergonomically designed. The findings of this study explored that during a lathe operation out of nine selected activities four activities namely loading of job, lathe machine tool setting and adjustments, rough facing, and unloading of finished job consumes more energy as compared to standards and therefore these activities should be emphasized the as for as ergonomic design of a lathe interface environment is concerned.
