Helical Interpolation (G02, G03) - Siemens SINUMERIK 802D sl Programming Manual

Commands Calling Axis Movements
2.1 Interpolation commands
Supplements to circular interpolation
A circular arc extending to multiple quadrants can be defined by the commands in
a single block. It is also possible to specify a full circle.

With the commands of "G17 G02 (or G03) I ⋅⋅⋅ J ⋅⋅⋅ F ⋅⋅⋅ Ln;", full-circle inter-
polation is repeated by n times. If address L is omitted, interpolation is executed
once. Execution of the commands with the single-block function ON causes full-
circle interpolation to be interrupted after the execution of one full-circle interpola-
tion.
2.1.4

Helical interpolation (G02, G03)

It is possible to execute linear interpolation in synchronization with circular interpo-
lation with the axis which is not included in the circular interpolation plane. This is
called helical interpolation. The command format is indicated below.
