Helical Interpolation (G02, G03) - Siemens SINUMERIK 808D Programming And Operating Manual

Selection of plane
Chamfer or fillet is possible only in the plane specified through the plane selection (G17, G18 or G19). These functions
cannot be used on parallel axes.
Note
No chamfer/rounding is inserted, if
No straight- or circular contour is available in the plane,
•
a movement takes place outside the plane,
•
The plane is changed or a number of blocks specified in the machine data, that do not contain any information about
•
traversing (e.g., only command outputs), is exceeded.
Coordinate system
After a block that changes the coordinate system (G92 or G52 to G59) or that contains a command of reference point
approach (G28 to G30), should not contain any command for chamfering or rounding of corners.
Thread cutting
The specification of fillet in thread cutting blocks is not permissible.

Helical interpolation (G02, G03)

With helical interpolation, two motions are superimposed and executed in parallel:
● A plane circular motion on which
● A vertical linear motion is superimposed.
Helical interpolation:
Note
G02 and G03 are modal. The circular motion is performed in those axes that are defined by the specification of the working
plane.
