The fabrication process for these alloys is crucial and plays an important role in the mechanical and metallurgical properties. Powder bed fusion (PBF) is a type of additive manufacturing technique, which includes selective laser melting (SLM) process as one of the 3D printing techniques that is used for CoCr fabrication. There are different SLM process parameters that affect the mechanical properties of the built part. The present work is the review of different parameters that affect the component manufactured using SLM. It was found that the laser scanning speed was the most influential factor for the density and hardness of the SLM formed CoCr alloys. It was also found that the mechanical properties of the SLM manufactured CoCr alloys are higher as compared to the cast alloys due to the dense, compact, homogeneous, and finer microstructure formed during the SLM process.

Both static and dynamic analysis is done for the bracket. With the objective to minimize the mass and increase the stiffness of the bracket, the new design is optimized using shape and topology optimization techniques. The optimized design given by CAE tool is then validated experimentally. The new design results in lower level of vibrations, contribute to lower mass along with lesser cost which is effective in air conditioning system as well as the efficiency of a vehicle. The results given by CAE tool had a very good correlation with the experimental results.

In the present study, the airflow control mechanism of an automotive heating, ventilating and cooling module for opening various doors/dampers were kinematically analyzed. A new method for cam design was developed which is faster and simpler than the existing oscillating link method. The existing design was modified for the same output using the new cam design method. It is shown that the torque required in the modified design is lesser than that in the existing design, thus lowering the effort required to rotate the cam from the control panel.
