Interpretation Of The Programmed Path - HEIDENHAIN TNC 620 User Manual

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.
