Helical interpolation with slope not permissible without 3rd dimension.

Description

Helical interpolation is the superposition of a circular interpolation (plane of 1st and 2nd main axis) and a linear motion in the 3rd main axis.

The message is generated if the position specified in the 3rd main axis (“Z axis”) is missing when helical motion is programmed.

Example:

Wrong:
N10   G17 G90 X-10 Y0 Z0 F500 G161
N20   G03 I0 J0 K10
:
N1000 M30
Correct:
N10   G17 G90 X-10 Y0 Z0 F500 G161
N20   G03 I0 J0 Z50 K10 (helical movement with 5 windings)
:
N1000 M30

Response

Class

1

Abort NC program processing.

Solution

Class

3

Check and modify NC program. Supplement the position in the 3rd main axis (“Z axis”) for helical motion.

Parameter

%1:

Initial value [0.1 µm or 0.0001°]

Start position of the 3rd main axis

%2:

Final value [0.1 µm or 0.0001°]

End position of the 3rd main axis

Error type

1, Error message from NC program.
