Abstract Fabrication efficiency has long been a challenge for additive manufacturing. Standard toolpath generation processes usually give rise to a significant number of non-productive motions that undermine production efficiency and degrade part quality due to frequent acceleration and deceleration in wasted motions.

Kinematics Constrained Toolpath Planning for Five-Axis Machines
2008This paper presents a new general toolpath planning method which considers two important types of constraints: the kinematics constraint and the geometric feature constraints. The contact kinematics theory for rigid bodies is used to incorporate the two types of constraints into our optimization framework.

A topological hierarchy-based approach to toolpath planning for multi-material layered manufacturing
Computer-Aided Design, 2006This paper proposes a topological hierarchy-based approach to toolpath planning for multi-material layered manufacturing (MMLM) of heterogeneous prototypes. The approach facilitates control of MMLM and increases the fabrication efficiency of complex objects by generating multi-toolpaths that avoid redundant tool movements and potential collisions.

Barrel cutter design and toolpath planning for high-efficiency machining of freeform surface
The International Journal of Advanced Manufacturing Technology, 2015Improvement of machining efficiency is always one of the most interesting problems in CNC machining. Traditionally, the ball-end cutter is widely used in sculptured surface machining for the highly flexible controllability. But the process efficiency is low especially for freeform surface machining, which generally needs multiple tool-paths. To improve
