Retraction 

Retraction describes a sequence of tool transitions, which allows its smooth departure from the last point of a working toolpath. As with an approach move, a retraction always lies on an imaginary plane that contains the work pass. This means that for the waterline operation’s moves, they are performed in the horizontal plane and for the plane operations in the vertical plane and for the drive operations on vertical mathematical cylinders defined by the appropriate curves etc. The available retraction methods depend on the selected operation type. The retraction method can be defined in the approach and retraction modes window.
