DOI: 10.1080/0951192x.2017.1407453
Abstract: ABSTRACT The space-filling curve (SFC) toolpath is characterised as having shorter toolpath length and ‘zero’ number of tool retractions. It is especially suitable for machining workpieces with complex boundaries. Though it is also always criticised… read more here.

DOI: 10.14733/cadaps.2021.714-737
Abstract: This paper presents a method to generate toolpaths for continuous B-Axis turning operations. Modern CNC turning centres allow continuous tool rotation about the B-Axis during operation; a suitably programmed tool orientation allows it to remove… read more here.
