“…The cutting characteristics of a ball nose tool are poor at the bottom tip of tool [1]. This coupled with the need for tight tolerances achieved by smaller feed forward step and smaller side step distances results in large machining times [2][3][4]. For reducing the machining time flat and radiused end mill tools have been adopted by industry to some benefits, but it is 5-axis machining, which allows the tool to be inclined relative to the part, that offers the most promise.…”

In this paper, we present an algorithm to find a gouge-free, multipoint of contact tool path for machining a triangulated surface. The algorithm is based on a proven 3-axis method of dropping a generalized radiused end mill on to a triangulated surface to find a gouge-free tool position. This algorithm is wrapped within the bisection algorithm to find a gouge-free 5-axis tool position that touches the triangulated part at two or more points. Our algorithm does not require solving systems of nonlinear equations and has been tested on several parts.

“…The method of dropping a radiused end milling tool along a fixed tool axis to find tool position in 3-axis machining is well established [3]. In this work, the 3-axis tool positioning algorithm has been generalized for 5-axis tool position for triangulated surfaces, allowing the tool to be dropped in any direction.…”
