The influence of the geometry of the lathe tool on the surface condition at the processing of the polyamide PA 66 – GF 30

Résumé

As it is known, the surface condition has two constituents: dimensional accuracy and roughness of the machined surface. In this study it is presented only the condition of the machined surface from the roughness point of view. As regards the geometry of the lathe tool, this study presents only the influence of two tool parameters: radius of the tool point and the end cutting edge angle.
