An offset algorithm for polyline curves

TL;DR: A wavy path pattern is adopted to fill the long and narrow cross-sections that are obtained from the slicing procedure of the thin-walled parts, which can bring in better deposition results and has more excellence in enhancing the efficiency.

TL;DR: In this article , a global continuous toolpath optimization for both solid and partial infill designs in large format additive manufacturing (LFAM) is presented, where outward contour and double offset schemes are used to generate smooth curves as the primary volume-filling paths; the remaining unfilled areas are covered by extending zigzag lines from the closest contours.

TL;DR: In this article, the tool orientation vectors of the initial cutter locations are projected onto the configuration-space, forming the orientation polyline, and a taper circle is defined in the C-space.

TL;DR: Empirical tests show that the proposed PS-curve offsetting method is very fast and robust with a near O(n) time-complexity, where n is the number of points in a PS-Curve.

TL;DR: A spiral topology toolpath that is to cut continuously with the minimum number of cutter retractions during the cutting operations is developed and allows the sculptured surface incorporating both steeper and flatter areas to be high-speed machined.

TL;DR: This paper presents algorithms for computing offsets of NURBS curves and surfaces that provide a good handle on error control and results in the fewest number of control points compared to all published work.

TL;DR: In this paper, a state-of-the-art and a survey of papers published in the field of pocket machining is given, showing the relationships between the shape, cutter, machine tool, and cutting conditions in the process of optimising the cost and lead time of pocket milling.
