“…V.K. Menon [6] has told that Productivity is the development of an attitude of mind and a constant urge to find better, cheaper, quicker and safe ways of doing a job which may be manufacturing an article or providing a service. Productivity is the balance between all the factors of production that will give the greatest output for smallest efforts.…”

One of the important sectors of the Indian economy is Industry. The Small Scale Industries (SSI) plays a vital role of the Indian Economy in terms of generation of employment, and base of entrepreneurial which helps to create and share the production. The study held in SSI in press shop, hands-on approach to workplace where material handling table work effectively, by considering the space constraint, time constraints, and availability of workers and different postures of workers.

“…They proposed an orthogonal array-based parametric deduction optimization technique and made a profoundly insightful contribution to CNC turning, wherein a fuzzy approach to surface roughness was used. S Tekeste et al [12] analyzed gears using finite element analysis software and found that the spur gear root was exposed to the greatest stress, and the gear root position was the position where the gear was easily damaged. Using CATIA and ANSYS software, an involute spur gear was modeled to investigate the contact stress under various operating conditions.…”

The high-precision machine tool's dynamic, static, and rigid nature directly affects the machining efficiency and surface quality. Static and dynamic analyses are essential for the design and improvement of precision machine tools to ensure good tool performance under difficult and demanding machining conditions. In this study, the performance of a high-precision machine tool was analyzed using its virtual model created using SOLIDWORKS. Static and model analysis using ANSYS Workbench software was conducted to establish the tool's static deformation and static stiffness. Furthermore, the static and dynamic characteristics of the tool were explored using a ﬁnite element modeling approach to study their performance. In particular, the structure, static force, modal, frequency spectrum, and topology optimization of machine tools were primarily analyzed. Using model analysis, we found the first four different frequencies (22.5, 28.9, 40.6, and 47.4 Hz) and vibration type, which suggested of a weak link. Further static structural analysis revealed that the deformation of the spindle was 67.26 μm. An experimental static rigidity analysis was performed, and the experimental deformation values of the tool and spindle were obtained. The static and dynamic characteristics, as well as the accuracy and efficiency of the finite element model, were verified by comparing the data with the Finite Element Analysis (FEA) results. Subsequently, we modified the settings and analysis model to ensure that the analysis results were consistent with the experimental findings. The error between the two results was within 1.56%. For an applied load of 5000 N on the spindle nose, the tool nose transient response was 0.5 s based on transient analysis. Under the condition that the structural deformation is as constant as possible, the lightweight structure may achieve the minimum weight and enhance the natural frequency; thus, the ideal structure will be obtained, and finite element analysis will then be performed. The optimal conditions for topology optimization include a lightweight structure, reduced structural deformation, and increased natural frequency of the structure. The developed method improves structural optimization, increases the ability of the product to be manufactured, and offers designers a variety of price-effective options.
