The determination of wormwheel toothing surface [PDF]
MATEC Web of Conferences, 2018 In heavy industry (metallurgy, mining), large-size worm gears designed to carry large loads are often used. However, their technology is very difficult and their manufacturing costs are very high. In practice, cone-derivative worm gears are most often used, which are machined by the envelope method using a rotary tool.

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms
Advanced Materials Technologies, EarlyView.3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...
