A graphical solution in CATIA for profiling end mill tool which generates a helical surface

The generation of a helical flute, which belongs to a helical cylindrical surface with constant pitch, can be made using end mill tools. The tools on this type are easiest to make than the side mills and represent a less expensive solution. The end mill profiling may be done using the classical theorems of surfaces enveloping, analytical expressed, as Olivier theorem or Nikolaev method. In this paper is proposed an algorithm, developed in the CATIA design environment, for profiling such tool's type. The proposed solution is intuitive, rigorous and fast due to the utilization of the graphical design environment capabilities. Numerical examples are considered in order to validate the quality of this method.
