Low Cost Automation (popularly known as LCA) is the introduction of simple pneumatic, hydraulic, mechanical and electrical devices into the existing production process or/and machinery, with a view to improving their productivity. These would also enable the operation of these equipments by even semi-skilled and unskilled labour, with a little training. This will involve the use of standardised parts and devices to mechanise or automate machines, processes and systems. LCA is a technology that creates some degree of automation around the existing equipment, tools, methods, people, etc, using mostly standard components available in the market with low investment so that the payback period is short. The current financial crisis faced all over the world has posed tremendous challenges on the manufacturing organisations. Even at low volumes, and large variety, they have to be competitive with minimum investment. Low-cost automation can play an important role in this situation. This paper discusses the case study of low cost automation for manufacturing of conveyor chain bushes and comparison of productivity of component using conventional horizontal milling machine. In this case study, the Low Cost Automation technique is used for manufacturing of conveyor chain bushes which requires two flat milling operations at both ends. In this paper the following studies are carried out 1. Reduction in cycle time due to automation, 2. Increase in productivity both qualitative and quantitative, 3. Less human intervention, indirectly reduction in operator fatigue, 4. Less rejection due to automatic controls and 5. Increase the profit of company with economic justification of payback period.

Mechanical fastening is a common method used to join composite materials. Mechanically fastened joints commonly adopted in aerospace structures are characterized by tight tolerances on both the fasteners and on the machined holes. Joints are the potential weakest point in the structure in order to make useful structure. The main objective of the bolted joint is to transfer the applied load from one part of the joint structure to the other through the fastener element. However, the presence of bolt holes induces high stress concentration which has thus recognized to be a source of damage developed during fatigue loading. The proposed work involves modeling of single bolted joint with the help of PRO/E for mild steel and E-glass fiber and analyzed with the ANSYS Workbench 14.5. Different stresses are evaluated theoretically and compared with that observed analytically for both the materials and it is found that maximum stresses are observed in E-glass fiber.
