Automatic 5-axis NC toolpath generation
Despite over a decade of research, automatic toolpath generation has remained an elusive goal for 5-axis NC machining. This thesis describes the theoretical and practical issues associated with generating collision free five-axis roughing and finishing toolpaths automatically from the CAD model of …

Craftsmanship and automation in flexible metal spinning
… has not been automated yet. The design of toolpaths by trial and error results in waste of time and material; the complexity introduced by the additional rollers has not been addressed properly yet; and only axisymmetric parts have been made so far, so the range of application is limited. …
