Slewing is the rotation of an object around an axis, usually the z axis.[1] An example is a radar scanning 360 degrees by slewing around the z axis. This is also common terminology in astronomy. The process of rotating a telescope to observe a different region of the sky is referred to as slewing.[2]
The term slewing is also found in motion control applications. Often the slew axis is combined with another axis to form a motion profile.
In crane terminology, slewing is the angular movement of a crane boom or crane jib in a horizontal plane.
The term is also used in the computer game Microsoft Flight Simulator wherein the user presses a key and they can rotate and move the virtual aircraft along all three spatial planes.
In the modern day use of CNC programs, slewing is a vital part of the process.[citation needed]
