Ergonomic Evaluation of the Man–Machine System for Productivity Assessment of Workers Working On a Lathe Machine
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering
Abstract
The ergonomic evaluation of man–machine systems is essential in manufacturing industries to ensure worker safety, comfort, and productivity. This study investigates the productivity assessment of workers operating lathe machines through ergonomic analysis. Anthropometric measurements, work posture observations, and task analysis were carried out to identify critical risk factors associated with prolonged standing, repetitive movements, and awkward body postures. Standard ergonomic assessment methods were employed to evaluate postural risks and musculoskeletal strain. The findings revealed that improper work surface height, non-optimal tool placement, and high physical workload contributed to reduced productivity and increased ergonomic risks. Based on the results, recommendations were made to optimize workplace layout, adjust machine and tool design according to anthropometric dimensions, and implement ergonomic interventions to enhance worker well-being and operational efficiency. The study emphasizes the role of ergonomics in improving both productivity and occupational health in lathe machine operations.
