Overview of higher-order functions

Higher-order functions of the SINUMERIK control are summarized on the following pages. This
provides you with an overview of the commands that go beyond the requirements laid down in
DIN 66025 and that facilitate significant improvements in the area of 5-axis machining.

8.1.1 Motion commands

Language elements with circular interpolation programming
CIP Circular interpolation through intermediate point
CIP X... Y... Z... I1=... J1= K1=..
CT Circle with tangential transition
CT X... Y... Z...
TURN Number of full circles to be traversed
G3 X... Y... I... J... TURN =
Additional parameters:
CR= Circle radius
I1, J1, K1 Intermediate points in Cartesian coordinates (in X, Y, Z direction)
AP= End point in polar coordinates, polar angle, also in the case of linear
interpolation
RP=
End point in polar coordinates, polar radius, also in the case of linear
AR=
interpolation
Opening angle
840D spline versions
CSPLINE Activation of cubic interpolating spline
ASPLINE Activation of Akima spline
Start and end condition
BNAT/ENAT zero curvature
BTAN/ETAN tangential transition
BAUTO/EAUTO C3-constant at first and last spline segment transition
