3.2.2.42 G112 Tangential correction "on"
The tangential correction of the C axis is switched on.
G112 AXES
AXES Validity identification and mode for rotation axis to be corrected. Only one
axis can be specified!
For path profiles with tangential or approximate tangential transitions, an
automatic tangential correction of a rotation axis is possible. For this, there
are two modes, which must be programmed as a numerical value under the
respective axis code letters.
Mode 1: Tangential correction from current position of the rotation axis
(standard)
Mode 2: Tangential correction with abrupt positioning of the rotation axis
at the start of the interpolation task on the angle programmed in the
geometry function
The pure correction only has an effect on circle profiles; the abrupt
positioning has an effect on all interpolation types.
)
Note!
This function does not calculate the current path vector in the
case of linear interpolation, i.e. the rotation axis is not aligned
automatically to the current path orientation.
The speed of the correction axis is corrected. The correction takes
place up to the maximum permissible axis speed (MK). If this
speed is exceeded, the path speed is reduced accordingly.
The function has a modal effect and can be deselected by G113.
G112 C1 The tangential correction for the C axis is switched on in normal mode
(pure correction without alignment on programmed angle).
