Abstract

Abrasive flow machining is a non-traditional production method applied to complex surfaces. It is a very useful method to achieve good surface quality which is very important nowadays. Especially, it is desired that the surface quality of materials with high corrosion and high heat resistance used in aviation and automotive industry is good. In this paper, the effects of abrasive flow machining (AFM) technique on the surface quality of material such as Ti-6Al-4V, especially used in the aerospace industry, have been observed. Taguchi method was used to see appropriate parameters and noise factors. The surface roughness values (R a ), material removal rate (MRR) were measured and the white layer formed by high heat during cutting was removed in the high cycle numbers. Wire electrical discharge machining (Wire EDM) process the white layer formed during cutting and corrected by the AFM technique is an undesirable layer on the material surface. Experiments were carried out by changing the abrasive concentration and abrasive mesh size in this abrasive media. The number of cycles was increased, and experiments were continued with up to 50 cycles. The best surface quality values were achieved in experiments using 180 abrasive grain size and 60% abrasive concentration. The surface roughness (R a ) values, material removal rate (MRR) were measured and the white layer formed by high heat during cutting was removed in the high process cycles.
