MACHINING COMPLEX CURVED SURFACES, USING SPHERICAL HEAD MILLS
The complexity of a piece configuration is determined by its functional role, mechanical loading system, operating conditions. Surfaces defining a piece in space can be expressed by means of parametric equations. A surface profile can be completely defined if that surface intersects two planes perpendicular to each other. Surface intersection curves resulting data with those plans have as expressions, analytical equations. Machining end mills with spherical head is a very complex process, due primarily blade arrangement on a spherical surface. The solution for successful machining of complex curved surfaces is to use mills with spherical head.
