Experimental Study to Evaluate the Machining Strategy on the Dimensional Accuracy and Finish of Ti6al4v Blisk Aerofoil
https://orcid.org/http://orcid.org/0000-0002-3798-8484
This study describes the optimization of an aerofoil machining process, which was established and followed for the machining of an entire integrated Titanium (Ti6al4v) Blisk. Blade aerofoil machining was carried out on a CNC five axis machine with a trunnion-type table arrangement. An ideal machining strategy and optimal cutting parameters had to be established before machining the entire Blisk. Dimensional consistency, including a good surface finish are fundamental requirements of a Blisk. In order to establish an optimal process of aerofoil machining, two sample materials (Ti6al4v) were selected and machining operations were carried out using different strategies. Dimensional inspection of the two samples was done, and the results were compared. The better strategy of the two was chosen and the same process was adopted in machining an entire integrated Blisk of 35 blades. Subsequent inspection was carried out. The process was found to give consistent dimensional results and a good surface finish across all blades, and proved to be an efficient and optimal method for Blisk Aerofoil machining.
