Converting existing conversational dialog programs into contour
programs
In this procedure you must copy an existing conversational dialog
program (.H file) into a contour description (.HC file). Since the two file
types have a different internal data format, an ASCII file must be created
as an intermediary for this copy procedure. Proceed as follows:
Select the Programming and Editing mode of operation
Calling the file manager
Select the .H program to be converted
Select the copy function: Enter *.A as the target file. The
TNC creates an ASCII file from the conversational dialog
program.
Select the created ASCII file.
Select the copy function: Enter *.HC as the target file. The
TNC creates a contour description from the ASCII file.
Select the newly created .HC file and remove all blocks—
except the BLK FORM workpiece blank definition—that do not
describe contours
Remove programmed radius compensations, feed rates and
M functions. The .HC file can now be used by smarT.NC.
