Experimental Studies On Surface Roughness of Spur Gear

Spur gears are used as a convenient way to transfer motion and power between shafts. One of the critical characteristics of spur gears is their surface roughness which affects their performance and durability. Proper hobbing techniques improve surface roughness, resulting in smoother operation and longer gear life. Hence, optimizing the hobbing processes during its manufacturing is an important step in achieving increased profitability and customer satisfaction. This paper investigates surface roughness of spur gear hobbing processes at various Taguchi levels, focusing on cutting speed and feed rate. The findings of the study revealed that Taguchi Grey Relational Analysis is an effective method for optimizing the hobbing process and reducing surface roughness. The research will contribute to the broader manufacturing field by inspiring further investigations into related processes and technologies.
