Release Note

As of Build V2.11.2010.02 the command #AKIMA STARTVECTOR... replaces the command #SET ASPLINE STARTTANG.... For compatibility reasons, this command is still available but it’s recommended not to use it in new NC programs.

#AKIMA STARTVECTOR {<axis_name><expr>}                                                                      (modal)

Components of the tangent vector, real value

Definition of start tangent using axis designations, a vector is specified whose direction corresponds to the direction of the tangent - the vector needs not therefore be normalised: However, all the components of the main axes must always be specified.

With tracking axes, the vector component is calculated from the ratio of the motion path of the tracking axis to the motion path of the contour:

Vector componentMitschlepp = SMitschlepp / SBahn where SBahn =
