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.
