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.

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.
