Abstract

The paper presents the method for fairing of High Speed Machining toolpaths to improve quality and efficiency of machining process. The proposed method has adopted the cubic Non-Uniform Rational B-Spline (NURBS) interpol generate a transition toolpath that connects two discontinuous machining toolpaths to be a smooth toolpath. Proposed method was applied to generate the transition toolpath for two cases: (i) corner-machining toolpath; (ii) layer-connection toolpath. The transition toolpath was proposed of circle form for the first case; and of helical form for the second one. Application of the cubic NURBS model for interpolation of transition toolpath satisfies C condition at the toolpath-connection point. Therefore it ensures stability, quality and productivity of High Speed Machining process.
