MOTION CONTROL: Steinmeyer Inc. has announced a new product to its extensive line of miniature ball screws. These 5-mm diameter screws are the perfect solution in applications such as micromanipulators, miniature robotics and compact actuators. Available in four nut styles: series 1112 single nut with connecting thread without wipers; series 1412 is a single nut with double flange and wipers on both ends; series 1214 is a cylindrical nut without wipers; and series 2422 is the company’s “quiet line” series, with a single nut that uses end-cap ball returns manufactured from plastic rather than metal tubes, making the screw virtually noiseless. All are available with leads ranging from 0.5 3 mm and offer a maximum speed of 4500 RPM.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
