“…The algorithm successfully computed toolpaths in all cases.

“…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. In an earlier paper [11], we proposed the drop-and-tilt method (DTM) which required the solution of a system of nonlinear equations to find the second point of contact. The new method differs in that rather than solving a system of nonlinear equations to find this second point of contact, an iterative method based on the bisection technique is used to find the tool orientation and position that gives multipoint, gouge-free tool position.…”

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.

In manufacturing engineering, especially in machining process, the definition of a reference plane is the first essential step within the overall process. After the reference plane is applied at the component all other features are processed with reference to this basic plane. During any process the component has to be clamped in order to resist the processing forces. There are several clamping systems available, such as pneumatic, magnetic systems or magneto-rheological (MR) systems. Depending on its stiffness the component is deformed due to the clamping forces, stresses are introduced. This effect can be neglected for components with a high stiffness and nearly rigid body behaviour. However, the deformation of low stiff components under clamping forces, e.g. sheet metals, is relatively large and is in the same range as the addressed accuracy of machining process. Due to the introduced elastic clamping stresses the component will reconfigure after clamping, this phenomenon is known as springback.The focus of this work is the design of a clamping system for flexible bodies in order to reduce the springback and to enable high precision processing. This clamping system consists in a set of supports, which adjust to the surface of the body without introducing stresses and causing no springback after the machining process. The number and the arrangement of the supports are optimized as a function of the intensity and position of the milling force and the geometrical and mechanical properties of the body as well. The functional unit of the clamping system is a cylindrical bodysliding nearly frictionless within a pipe. Numerical simulation is used for configuration and optimization. The developed clamping systems can also be used to process freeform shaped bodies. In der spanenden Bearbeitung ist die Schaffung einer Referenzfläche, an der sich alle weiteren Bearbeitungen orientieren, der erste wesentliche Schritt. Zur Aufnahme der Bearbeitungskräfte werden Werkstücke üblicherweise gespannt, beispielsweise über pneumatische, magnetische oder magnetorheologische Systeme. Je nach Steifigkeit erfährt das Werkstück dadurch Deformationen, die wiederum Spannungen hervorrufen. Während dieser Effekt für Werkstücke mit hoher Steifigkeit vernachlässigt wird, können die Deformationen bei weniger steifen Werkstü-cken, wie beispielsweise bei Blechen, in der gleichen Größenordnung wie die geforderte Bearbeitungsgenauigkeit liegen. Die nach der Bearbeitung auftretende Rück-federung macht die angestrebte Bearbeitungsgenauigkeit zunichte.Corresponding author: C.
