● MD21000 $MC_CIRCLE_ERROR_CONST
● Start radius multiplied by MD21010 $MC_CIRCLE_ERROR_FACTOR
This means that for small circles the tolerance is a fixed value (MD21000
$MC_CIRCLE_ERROR_CONST), and for
large circles it is proportional to the start radius.

In the context of the predefined tolerances, conflicting circle data is compensated
essentially by moving the center point of the circle. Please note that the deviation
between
the
programmed
center point and the actual center point can reach the order of
magnitude set with machine data MD21000 $MC_CIRCLE_ERROR_CONST and/or MD21010
$MC_CIRCLE_ERROR_FACTOR. In the case of circles which are almost full circles in
particular, this can also lead to contour deviations of the same order of magnitude.

Description: Factor for permissible radius difference.
Defines the factor for large circles by which the starting radius and end radius may
deviate from each other
(see also MD21000 $MC_CIRCLE_ERROR_CONST (circle end point monitoring constant).
When a circle is programmed, both conditions (that the distances from the programmed
center
point to
the start and end points (circle radius) must be the same and that the
center point of the circle must be located on the perpendicular bisector of the
straight line connecting the start and end points (perpendicular bisector of the
circular plane)) apply.
The fact that the circular parameters can be freely programmed means that these
conditions are not usually met exactly in the case of circular-path programming with
I, J, and K (the circle is "overdefined").
The maximum permissible difference between the two radii that is accepted without an
alarm,
as well
as the distance between the programmied center point of the circle and
the perpendicular bisector described above, is defined by the larger value in the
following data:
● MD21000 $MC_CIRCLE_ERROR_CONST
● Start radius multiplied by MD21010 $MC_CIRCLE_ERROR_FACTOR
This means that for small circles the tolerance is a fixed value (MD21000
$MC_CIRCLE_ERROR_CONST),
and for
large circles it is proportional to the start radius.
