With this function, the rotary axis movement is changed into exponential functions vis-a-vis the linear axis
movements.
When exponential function interpolation is performed, linear interpolation is performed between the other
axes and the linear axis. This makes it possible to machine tapered grooves (regular helix machining of
tapered shapes) whose helix angle is always constant.
The function can be used for slotting and grinding end mills and other tools.
