Abstract
This paper offers some thoughts on the synthesis of planar guiding mechanisms for thermal cutting. One of the links, namely the cutting torch holder, performs a rotation about a virtual axis that is not carried out as a real joint. The considerations are presented with respect to the boundary conditions of the process, mainly the design and collision space restrictions and the demands on the available tilting angle. As it will be shown, many of the existing solutions in the literature and industry are variants of – or derived from - one 6-bar linkage based on a parallel crank mechanism. Additionally one solution is given, that is not related to the 6-bar linkage.
