Circular Interpolation With Intermediate Point And End Point - Siemens SINUMERIK 840D sl Programming Manual

Motion commands
9.6 Circular interpolation
9.6.6 Circular interpolation with intermediate point and end point (CIP, X... Y... Z...,
I1... J1... K1...)
Function
CIP can be used to program arcs. These arcs can also be inclined in space. In this case, you
describe the intermediate and end points with three coordinates.
The circular movement is described by:
• The intermediate point at addresses I1=, J1=, K1= and
• The end point in Cartesian coordinates X, Y, Z.
The traversing direction is determined by the order of the starting point, intermediate point
and end point.
Syntax
CIP X... Y... Z... I1=AC(...) J1=AC(...) K1=(AC...)
Meaning
CIP:
X Y Z :
I1= J1= K1= :
=AC(...):
=IC(...):
222
Circular interpolation through intermediate point
End point in Cartesian coordinates. These specifications depend on
the travel commands G90/G91 or ...=AC(...)/...=IC(..)
Circle center point in Cartesian coordinates (in X, Y, Z direction)
The identifiers have the following meanings:
Coordinate of the circle center point in the X direction
I1:
Coordinates of the circle center point in the Y direction
J1:
Coordinates of the circle center point in the Z direction
K1:
Absolute dimensions (non-modal)
Incremental dimensions (non-modal)
