Abstract—Closed die forging is a very complex process, and measurement of actual forces for real material is difficult and time consuming. Hence, the modelling technique has taken the advantage of carrying out the experimentation with the proper model material which needs lesser forces and relatively low temperature. The results of experiments on the model material then may be correlated with t...

Accuracy is the key issue in the precision forging. Geometric and dimension errors are the two significant defects found in most of near net or net shape manufacturing process. It becomes more critical for complex part such as an AUV propeller blade. In this study, geometric error was quantified by comparing the blade profile obtained from nominal geometry of the blade and the profile construct...

Since 1986, more than 500 million powder forged (PF) connecting rods have been manufactured and installed in automobiles worldwide. The application of forging a preformed near-net shape consolidated from metal powder has been widely accepted since the early eighties and today is the preferred manufacturing technique for 60% of the connecting rods manufactured in North America. The remaining por...

Musculoskeletal disorders (MSDs) are common health problem throughout the world and a major cause of disability in the workplace. This study was conducted among workers of a small scale forging Industries. The small scale forging units involve various kinds of high repetitive processes like Blanking, cutting, shearing, furnace loading, hammering, punching and trimming etc. the workers performin...
