26-84 PROGRAM PENTRU GENERAREA LINIILOR ELICOIDALE ALE SCULELOR

THE PROGRAMME FOR GENERATING OF TOOLS HELICAL LINES
The paper presents the basic elements for determination of the points of tools helical lines. The evidence presented in this paper serve to check the car in 3D helical surfaces of cast iron tools used on machining centres in the automotive industry, tools to claim compliance with the strictness of helical surfaces that define their geometry.
Keywords: parametric equations of the helical lines
