Collision-free Tool Motion Planning for 5-Axis CNC Machining with Toroidal Cutters

Computer-Aided Design
Collision detection is a crucial part of CNC machining, however, many state-of-the-art algorithms test collisions as a post-process, after the path-planning stage, or use conservative approaches that result in low machining accuracy in the neighborhood of the cutter’s contact paths.

Integrated Engineering of CAR‐T Cells for Solid Tumours

Cell Proliferation, EarlyView.
Solid tumours pose multifactorial barriers including antigen heterogeneity, immunosuppressive microenvironment, and poor T‐cell trafficking, limiting CAR‐T efficacy compared to hematologic malignancies. Integrated engineering strategies are essential, combining logic‐gated receptors for precision, metabolic‐epigenetic reprogramming for resilience, and ...

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.

Stability prediction for toroidal cutters with non-uniform helix angles in the milling process

Journal of Physics: Conference Series
Abstract Milling technology is widely used in the modern industry. However, traditional tools cannot meet the requirements of suppressing chatter as well as improving the machining efficiency in some cases. Therefore, the idea of tools with non-uniform helix angles is proposed to remove materials in the milling process.
