Investigation of chips morphology after turning of materials applied in aerospace industry

In the paper is presented analysis of chips morphology after turning of three groups of modern materials applied in aerospace industry: titanium alloys, stainless steels and heat resistant alloys. Various feed rates f and corner radiuses rε as well as recommended cutting speed vcfor given group of work material were applied in machining tests. Range of burrs on thinner edges of chips and serration on the chips surface occurrence were identified dependent on work material and uncut chip thickness (values of the f and rε). In the research height h and distance b between the burrs as well as distance a between serrated segments were measured. It was identified two kind of burrs connected with different physical phenomenon and specified h and b dimensions
