Abstract: In orthopedics a lot of specialized tools and reconstructive elements are being used. Most of these tools are bounded by helical surfaces, significantly different from those used in similarly constructions with general character. The characteristics of these elements are defined by the structure and the composition of the material where the reconstructive elements are mounted, namely the bone. Hence result the necessity to imagine new fastening elements on screw type, characterized by a specific form. This paper presents a method developed in a CAD environment for profiling tools bounded by the revolution surfaces of the specifically helical drill used in the orthopedic reconstruction surgery. On the other hand, the surgery tools, like drills, must have cutting tools distinct from those used in the inorganic materials. Their shape has to assure a minimum heating of the machined material and to allow a good ejection of the material resulted from processing. An analysis of the cutting zone of the helical drills is also made by graphical methods, based on the CATIA design environment. A profiling algorithm of the end mill tool for generating helical surfaces with imposed axial section is also defined.
