The rotary axes are interpolated linearly syn-
chronous to the path motion. In this interpola-
tion type, the orientation curve depends on the
machine kinematics. It can be used in all
cases in which it is not necessary that the tool
moves on a precisely defined surface in the
workpiece coordinate system. This is the
case, for example, in mold-making when ball
mills are used.

Axis/linear interpolation
Linear interpolation of the machine axes
The tool vector always moves in a plane set
up by the start and end vectors. The
interpolation type is frequently used in the
milling of aircraft structures because the
pockets mostly have flat and inclined walls. It
is also recommended when using toroidal
millers for face milling.
