What are the most significant technology advances (software or hardware) that are improving these applications for 5-Axis machining? Obviously there are advances in position accuracy and repeatability of the feedback devices and more available processing power, but are there also algorithm developments and more sophisticated application programming techniques that are driving the advances in this area as well?
The more axis, the more chance of accumulating errors. Without a closed loop, 5-axis machines would be machining nightmares. I have a closed loop mill and I recently built an open-loop one for little projects. In the open-loop one, I can see where I lose steps. Over time, if that problem isn't addressed, the home(zero) drifts.
As a side note, I plan on adding a CNC rotary table to one of my mills. Closed loop is a must. That will make my design harder. (closed loop on a stepper? Yikes!)
This Gadget Freak Review looks at a keyless Bluetooth padlock that works with your smartphone, along with a system that tracks your sleep behavior and wakes you at the perfect time in your sleep cycle to avoid morning grogginess.
Siemens released Intosite, a cloud-based, location-aware SaaS app that lets users navigate a virtual production facility in much of the same fashion as traversing through Google Earth. Users can access PLM, IT, and other pertinent information for specific points on a factory floor or at an outdoor location.
Since 1987, teams of engineers around the world have built solar cars to participate in a road race around Australia called the World Solar Challenge, being tested on the race time, kilometers traveled, practicality, and energy used by the vehicles they invent.
