The Effect Of Cryogenic Cooling On Surface Roughness Of Titanium Alloy: A Review

Abstract

Titanium alloy is a unique material that can maintain its high strength–weight ratio during elevated temperatures. It is one of the important metal parts of the engine components and aircraft structural. Surface roughness is one of the important parameters used in evaluating the quality of finish machined surfaces because of these parts of components in aerospace industry are manufactured to reach high consistency level. To improve the surface roughness of the work materials, the use of coolant in manufacturing operations such as turning process must be considered properly. The application of cryogenic coolant in machining process was analyzed in details in this review. The study was based on the application methods in machining operations which is the turning process on titanium alloy and the condition of work materials by looking at surface roughness values when using the coolant. The findings showed the most constructive method for machining operations was cryogenic cooling. This is because of its capability in producing better surface finishes by reducing the cutting temperature during machining operation, subsequently, enhancing the quality and function of the products or components
