Unified Approach Improves the Accuracy of Five-Axis Machine Tools

Ph.D. students Jennifer Creamer and Le Ma work in Missouri University of Science and Technology’s Precision Motion Control Laboratory. (Credit: Missouri S&T) Five-axis machine tools are computer-numerically controlled (CNC) machines that can move, cut, or mill a part on five different axes at the same time. Because of inherent geometric errors, manufacturers must make adjustments when calibrating these machines. Several different approaches exist to help compensate for the errors, but none of them provides a complete picture. Researchers at Missouri University of Science and Technology set out to find a way to eliminate that piecemeal approach and develop a new way to capture complicated geometric errors and automatically generate compensation tables.

Technique Could Lower Costs of Making Bioplastics and Biofuel

Ulrica Edlund, professor of polymer technology. While abundant in nature, cellulose is difficult and expensive to find in pure or high-quality form. A Swedish research team has developed an efficient, accurate, and non-destructive way to detect the occurrence and purity of cellulose. The technique can be applied in mixtures of biopolymers as well.

4D Printing: New dimension for additive manufacturing

A team of Lawrence Livermore National Laboratory researchers have demonstrated the 3D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity. The micro-architected structures are fabricated from a conductive, environmentally responsive polymer ink developed at the lab.
