Importance of mounting tolerances for modular encoders
Modular encoders are very susceptible to mounting misalignment. Since modular encoders have no bearing, they rely solely on the accuracy of the motor and encoder manufacturing process.
What influences accuracy of rotary tables?
When determining the influencing factors of accuracy on a rotary table, the first thing would be to look at the mechanics of the table itself.
Exposed linear encoders for direct drives
Linear motors have made irreversible inroads into highly dynamic applications such as manufacturing and measuring equipment in the semiconductor industry, in PCB assembly machines, textile machines and in automation.
Influence of position measurement on accuracy in 5-axis machining
High strength and low weight are essential for the aeronautics and space industry. Integral construction has established itself as the way to minimize the weight of "airborne" parts: components with complex structure are manufactured completely from a single blank. Metal removal levels can be as high as 95 %. This high "buy-to-fly" rate leads to high costs for the raw material of the blanks.
Camera stabilization for filming action sequences from boats and moving platforms
Figure 1: PERFECT HORIZON Founder and President David Grober on the set of Talladega Nights Did you know that a RENCO encoder is used in camera stabilization equipment found on many boats and moving platforms that film for television and movies, allowing filmmakers ...
A government-sponsored titanium-cutting machine with 50% faster cutting speeds
Did you know that HEIDENHAIN encoders are used in a new government-sponsored titanium-cutting machine now showing great promise? This is of particular note to the aerospace industry where strong but lightweight parts make a critical difference in the success of aircraft missions. Originally appeared in ...
The new generation of angle encoders come of age
HEIDENHAIN’s angle encoders with integral bearing have long been the standard for applications where angular measurement in the range of a few angular seconds is necessary. The encoders are characterized by their simple mounting and very high accuracy.
Lens positioning at sporting events for HD television cameras
Courtesy of Sportsvision Did you know that HEIDENHAIN ERN series encoders are used to position lenses in many of those large, high quality television cameras used in professional sports? Sportvision, Inc., well known for their virtual Yellow 1st and Ten™ Line seen when viewing ...
Accuracy, repeatability and resolution: What’s the difference?
Three terms that are well used in the feedback industry are “accuracy”, “repeatability” and “resolution”. These words are sometimes used interchangeably and should not be.
Aspects of 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.
