Abstract: Aluminium material is extremely used in many manufacturing industry sectors, there are several uses of aluminium, i.e., formability, high strength, thermal resistance, flexibility and high resistance towards corrosion. The advantages in different engineering fields demand various machining operations to be performed on metal matrix composites (MMCs). In the present investigation, the machine vision technique is used to observe roughness of surface in turning of MMCs composites. The process parameters considered are weight percentage of titanium carbide, feed, cutting speed and depth of cut. Experiments are planned and executed according to central composite design technique on all geared lathe machine using TiCN-Al2O3 tool insert. During machining operation the machining surfaces are captured through machine vision technique. A program is written in MATLAB which is used to analyze Ga values for bitmap of captured images and stylus probe instrument is used to estimate surface finish of machined surfaces.
