Abstract:
The objective of this paper is to find an optimum temperature range in which no unfilling is found in hot
forging of connecting rod made of 42CrMo4. Connecting rod is one of the most important components in
automobile. It is very helpful in machines where reciprocating motion is converted into rotary motion.The
current rejection rate due to unfilling is 2.1 %. So, process parameters affecting Unfilling were identified.
Other parameters affecting were also discussed in detail in So, in order to achieve the required objective
of minimizing Unfilling, simulation of temperature at which billet is forged (the most affecting parameter
for unfilling defect) is done using DEFORM 3D software, which is a powerful tool for analyzing material
flow. The validation of the simulated range will be taken and experimented in the industry.
