Explanation:
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 compensation plane.
The tangent at a point on a path is regarded as parallel to the tool orientation if the angle between the two directions is
less than the limit value defined by MD21080 $MC_CUTCOM_PARALLEL_ORI_LIMIT.
However, in circumferential milling, straight lines running parallel to the tool orientation are permissible, as well as circles
with a circle plane perpendicular to the compensation plane (application with smooth retraction from the groove).
Straight lines in the direction of the tool orientation are not permissible in face milling (CUT3D, CUT3DF, CUT3DFS).
Reaction:
Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy:
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 compensation between the various sections.
Programm
continuation:
Clear alarm with NC START or RESET key and continue the program.

[Channel %1: ] Block %2 helical axis is not parallel to tool orientation
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
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.
Reaction:
Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy:
Orient helix axis perpendicular to the machining plane.
Programm
continuation:
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 revolution not
possible
Parameters:
%1 = Channel number
%2 = Block number, label
Explanation:
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 unlimited 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.
Reaction:
Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy:
Use cutter with smaller radius or program motion block on blocks with no more than one revolution.
Programm
continuation:
Clear alarm with NC START or RESET key and continue the program.
