Energy Efficiency in Machine Tools

Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock removal rate, while the power consumption during finishing is significantly lower. There is a very close interdependence between the individual components and subassemblies of a machine tool and aspects of productivity and quality. From a detailed examination of manufacturing processes to the power consumption of individual components, potential for savings can be evaluated and measures can be defined for the efficient use of energy.

Fabricating Custom Components from Stock Optics

Two quantities are perennially in short supply on engineering projects: time and money. When it comes to producing custom optical components in less time, for less money, one feasible approach is to modify off-the-shelf components to meet customers’ unique requirements. This tactic is particularly valuable in the prototyping stage or for one-of-a-kind instruments, when a full production run would be unjustifiably expensive and take an unreasonably long time.

Reverse Engineering Helps NASA Analyze Icing Conditions

ROMER Absolute Arm with integrated laser scanner Hexagon Metrology North Kingstown, RI 800-274-9433 While air travel is considered the safest form of transportation, research continues to better understand ice buildup and its affects on aerodynamics. At NASA’S Glenn Research Center in Cleveland, OH, engineers in the Icing Branch have been studying the mechanics of ice buildup since the 1940s.

Data Acquisition System Helps NASA Improve Aircraft Crash Performance

Data acquisition system DTS (Diversified Technical Systems) Seal Beach, CA 562-493-0158 Aircraft impact testing and hard landing tests are an important part of research for understanding crash dynamics and improving occupant safety at NASA’s Langley Research Center in Hampton, VA. DTS small, onboard data acquisition systems (DAS) are used in many tests at Langley, since they are rugged enough to survive harsh impacts and still accurately deliver critical test data.
