MOTION CONTROL: Helical Products Co.’s “machined” springs can provide linear deflection rates. Unlike traditional wire wound springs, virtually all residual stresses are absent. There are no internal stresses to overcome before deflection occurs, which can be the case with traditional springs. With machined springs, all coils deflect under load.
One big advantage of machined springs with two or more integral coils is that not only are there redundant elastic elements should a failure occur, but a failed element (coil) will be physically trapped by a second coil, (or multiple coils). In many cases a broken spring will continue to function.
There is no tendency for machined springs to squirm when deflected and no restraint is required to resolve the free moment. Multiple starts (coils) make loading points irrelevant on the radius of the spring and also increase parallelism accuracy. With machined springs, perpendicularity, parallelism, lateral bending, axial and torsional rates can be for all intents and purposes guaranteed.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Two new introductions in the world of motion drives for automation are moving toward use of standard Ethernet communications, eliminating the use of custom hardware.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
