Initial tool path selection of the iso-scallop method based on offset similarity analysis for global preferred feed directions matching
TL;DR: This paper presents a novel initial path selection method to make whole iso-scallop tool paths and the preferred direction field consistent as much as possible and achieves a better matching for the selected feed directions and a shorter overall length compared with some existing tool path generation methods.

CNC Tool Path Generation for Freeform Surface Machining Based on Preferred Feed Direction Field
TL;DR: This paper presents a novel method to generate three-axis CNC tool paths for machining freeform surfaces based on a preferred feed direction field based on the parametric model of the surface.

A novel adaptive slicing algorithm based on ameliorative area ratio and accurate cusp height for 3D printing
TL;DR: This study aims to develop a novel adaptive slicing method based on ameliorative area ratio and accurate cusp height for 3D printing using stereolithography (STL) models that can reach a trade-off between the building time and the surface quality.

A novel feed rate scheduling method with acc-jerk-continuity and round-off error elimination for non-uniform rational B-spline interpolation
TL;DR: In this article , a S-shape-based feed rate scheduling method for three-axis NURBS tool paths is presented, which can reduce high chord errors and round-off errors, and generate continuous velocity, acceleration, and jerk profile.
