Path criterion
The size of the rounding area can be controlled by path criteria
ADIS
and
ADISPOS
. These
are the precoincidences for the block change.
ADIS
and
ADISPOS
describe the distance,
which the rounding block may begin, at the earliest, before the end of the block or the
distance after the end of block within which the rounding block must be terminated.

Example for rounding an angular block transition
Acute angles produce rounding curves with a large degree of curvature and therefore cause
a corresponding reduction in velocity.
Parameterization of the path criterion
•
ADISPOS
is programmed in the same way as
ADIS
, but must be used specifically for
movements in rapid traverse mode (
G00
).
•
ADIS
and
ADISPOS
are preset in the part program.
For example,
ADIS = 0.3
indicates a path criterion with a rounding distance of 0.3 mm
(
ADISPOS
is the same).
Scope of the path criterion
•
ADIS
or
ADISPOS
must be programmed. If the default is "zero",
G641
behaves like G64.
•
If only one of the blocks involved is rapid traverse
G00
, the smaller rounding distance
applies.
•
If a very small value is used for
ADIS
, the control must make sure that every interpolated
block, even an intermediate rounding block, contains at least one interpolation point. The
maximum path velocity is thereby limited to
ADIS
/interpolation cycle.
•
Irrespective of
ADIS
and
ADISPOS
, the rounding area is limited by the block length.
