Use smaller cutters or allow for a part of the cutter radius at the time of contour program-
ming.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 path is parallel to tool orientation
%1 = Channel number
%2 = Block number, label
In a block with spline or polynomial interpolation, the corrected path runs in at least one
point parallel to the tool orientation, i.e. the path has a tangent perpendicular to the com-
pensation plane.
Straight lines running parallel to the tool orientation are permissible, as well as circles,
with a circle plane that is perpendicular to the compensation plane (application in smooth
retraction from a slot).
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Do not use splines or polynomials when writing the contour section, but straight lines and
circles instead. Divide up the tool piece geometry and deselect the cutter radius compen-
sation between the various sections.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 helical axis is not parallel to tool orientation
%1 = Channel number
%2 = Block number, label
With active tool radius compensation a helix is only permissible if the helix axis is parallel
to the tool, i.e. the circle plane and the compensation plane must be identical.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Orient helix axis perpendicular to the machining plane.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 tool radius compensation for ellipse with more than one rev-
olution not possible
%1 = Channel number
%2 = Block number, label
When machining the inside of an ellipse, in parts of the ellipse the curvature radii are
greater than or smaller than the cutter radius compensation.
In ellipses, in this case the block would be split up into 4 subblocks with curvature radii
that are greater than and less than the compensation radius. Over several revolutions,
there would be a tremendous increase in the amount of calculation required by the unlim-
ited number of resulting subblocks, and therefore this situation is rejected by the error
message.
If compensation is possible everywhere or nowhere on the ellipse, then ellipses are also
permissible that cover more than one full revolution.
