Programming
This type of interpolation can be used to program points (using G1) or polynomials (using
POLY) for the two curves in space. Circles and involutes are not permitted. A BSPLINE spline
interpolation and the "Combine short spline blocks" function can also be activated.
Additional information about function "Combine short spine blocks", see Function Manual Basic
Functions.
Other types of splines (ASPLINE and CSPLINE) and the activation of a compressor using
COMP... are not permissible.
The motion of the two contact points of the tool can be predefined up to the 5th degree when
programming the orientation polynomials for coordinates.

contact point of the tool and additional pol‐

Parameter
ORICURVE Interpolation of the orientation specifying a movement
between two contact points of the tool.
XH YH ZH Identifiers of the coordinates of the second contact point
of the tool of the additional contour as a curve in space
PO[XH]=(xe, x2, x3, x4, x5)
PO[YH]=(ye, y2, y3, y4, y5)
PO[ZH]=(ze, z2, z3, z4, z5)
Possible polynomials
Apart from using the appropriate end points, the curves
in space can also be programmed using polynomials.
xe, ye, ze End points of the curve in space
xi, yi, zi Coefficients of the polynomials up to the 5th degree
