Fundamentals
Introduction to smarT.NC
With smarT.NC you can easily write structured conversational programs
in separate working steps (units) and, if you want, edit them with the
conversational editor. Since the only data basis for smarT.NC is the
conversational program, you can modify data with the conversational
editor, for example, and show them in the form view.
Immediately understandable input forms in the right half of the screen
make it easier to define the required machining parameters, which are
also displayed in a help graphic (lower left quarter of the screen). The
structured program layout in a tree diagram (top left quarter of the screen)
provides you with a quick overview of the working steps in a part
program.
Fundamentals
The separate and universal operating mode smarT.NC provides an
alternative to the well known conversational programming. As soon as
you have defined a machining step you can graphically test it and/or run
it in the new operating mode.
Parallel programming
You can also create and edit smarT.NC programs at the same time that
the TNC is running another program. Simply switch to the Programming
and Editing operating mode and open the desired smarT.NC program
there.
If you want to edit the smarT.NC program with the conversational editor,
select the OPEN WITH function in the file manager, and then press
CONVERSTL.
16
Programs/Files
The TNC keeps its programs, tables and texts in files. A file designation
consists of two components:
PROG20 .HU
File name File type
smarT.NC uses mainly three file types:
Unit programs (file type .HU)
Unit programs are conversational programs that contain two additional
structuring elements: The beginning (UNIT XXX) and the end (END OF
UNIT XXX) of a machining step.
Contour descriptions (file type .HC)
Contour descriptions are conversational programs. They must only
contain path functions that can be used to describe a contour in the
machining plane. The following elements are permitted: L, C with CC,
CT, CR, RND, CHF as well as the FPOL, FL, FLT, FC and FCT elements for FK
free contour programming
Point tables (file type .HP)
smarT.NC saves in point tables the machining positions that you
defined using the powerful pattern generator.
As a default, smarT.NC automatically saves all files in the
TNC:\smarTNC directory. However, you can also select any
other directory.

arrow keys and press ENTER, or
In order to write a new machining program, press the NEW
FILE soft key. smarT.NC opens a pop-up window.
Enter a file name with the extension .HU, and confirm with
ENT.
Confirm with the MM (or INCH) soft key or screen button.
smarT.NC creates an .HU program with the selected units
of measurement and automatically inserts the program
header form.
The data for the program header form are mandatory, since
Fundamentals
they are globally valid for the entire machining program. The
default values are specified internally. Change the data if
necessary, and save them with the END key.
In order to define machining steps, press the EDIT soft key
to select the desired machining step.

File management with smarT.NC
As mentioned previously, smarT.NC differentiates between three file
types: unit programs (.HU), contour descriptions (.HC) and point tables
(.HP). These three file types can be selected and edited in the file
manager in the smarT.NC operating mode. Contour descriptions and
point tables can also be edited if you are currently defining a working unit.
You can also open DXF files from within smarT.NC in order to extract
contour descriptions (.HC files) and machining positions (.HP files) from
them (software option).
The file manager in smarT.NC can also be fully operated with the mouse.
You can even use the mouse to change the sizes of the windows within
the file manager. Click the horizontal or vertical separating line, and drag
it to the desired position with the mouse.

Calling the file manager
To select the file manager, press the PGM MGT key: The TNC displays
the file manager window (the figure at right shows the default setting).
If the TNC displays a different screen layout, press the WINDOW soft
key on the second soft-key row)
The top window on the left shows the available drives and directories.
Drives designate devices with which data are stored or transferred. A
drive can be the hard disk of the TNC, directories connected via the
network, or USB devices. A directory is always identified by a folder
symbol to the left and the directory name to the right. Subdirectories are
shown to the right of and below their parent directories. A triangle
pointing to the right in front of the folder symbol indicates that there are
further subdirectories, which can be shown with the right arrow key.
The lower window on the left shows a preview of the file contents if an
.HP or .HC file is highlighted.
Fundamentals

The wide window on the right shows you all files that are stored in the
selected directory. Each file is shown with additional information,
illustrated in the table below.
