Interpretation of the programmed path
With the
FUNCTION PROG PATH
function, you decide whether the
control will apply the 3-D radius compensation only to the delta
values, just as before, or rather to the entire tool radius. If you
activate
FUNCTION PROG PATH
, the programmed coordinates
exactly correspond to the contour coordinates. With
FUNCTION
PROG PATH OFF
, you deactivate this special interpretation.
Procedure
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the
PROGRAM FUNCTIONS
soft key
Press the
FUNCTION PROG PATH
soft key
You have the following possibilities:
Soft key Function
Activate the interpretation of the programmed
path as the contour
The control takes the full tool radius
R + DR
and
the full corner radius
R2 + DR2
into account for 3-
D radius compensation.
Deactivate the special interpretation of the
programmed path
The control only uses the delta values
DR
and
DR2
for 3-D radius compensation.
If you activate
FUNCTION PROG PATH
, the interpretation of the
programmed path as the contour is effective for 3-D compensation
movements until you deactivate the function.
