Abstract
The machining process of free-form surfaces with computer aided design:manufacture (CAD:CAM) systems has to be in accordance with the geometrical specifications. Usually, the cutter path strategy is defined in order to respect these specifications (essentially, form deviation and roughness) as much as possible. Unfortunately, there is no obvious link between geometrical specifications and the CAM parameters that characterize the cutter path strategy. The aim of this paper is to propose links between CAM parameters and geometrical specifications so that the machined surface has the desired quality. These links cannot be made without taking the influence of the form convexity into account. In addition, the parameter values can be optimized with respect to the machining time.
