The anisotropy of mechanical strength on a 3D printed model can be controlled in a multi-
axis 3D printing system as materials can be accumulated along dynamically varied …

Industrial robot provides a promising alternative in freeform surface milling. However, due to
its low stiffness, it is difficult to guarantee the machining quality. While existing research …

Hot-wire cutting is a subtractive fabrication technique used to carve foam and similar
materials. Conventional machines rely on straight wires and are thus limited to creating …

CNC machining is the leading subtractive manufacturing technology. Although it is in use
since decades, it is far from fully solved and still a rich source for challenging problems in …

Depth cameras and 3D scanners significantly simplify the procedure of geometric modeling.
3D surfaces have become more widespread, leading to a great demand for noise removal …

We propose a novel method to compute smooth preferred feed direction fields with high
material removal rates to construct CNC tool paths for five-axis machining with ball-end …

Additive and subtractive hybrid manufacturing (ASHM) involves the alternating use of
additive and subtractive manufacturing techniques, which provides unique advantages for …

We propose a path-planning algorithm for 5-axis flank CNC machining with general tools of
varying curvature. Our approach generalizes the initialization strategy introduced for conical …

Conventional material extrusion additive manufacturing (AM) processes require the user to
make a trade-off between surface quality and build time of the part. A large bead filament …

This paper presents a learning based planner for computing optimized 3D printing toolpaths
on prescribed graphs, the challenges of which include the varying graph structures on …
