In the paper are presents the results of CNC manufacturing applications. Material what was processed was Inconel 718 who is a heat resistant super alloys. Was presented the cutting tools insert, characteristics and methodologies haw to obtain much more productivity and in the same time, the cutting tool parameters to keep much more time possible the geometrical characteristics of the cutting tools. Was analyzed the wear and what are the most common type of wear who appear at this special applications. Using high technical metrology equipment was underline the structure and the value of insert wear.
