HEIDENHAIN includes a set of NC subprograms with
DataPilot for engraving inscriptions (large and small
letters, numbers, and various special characters).

The installation program transfers these NC
subprograms together with the NC sample programs
Grav_Sti and Grav_Man into the machine “BEISPIEL.”
The names of the NC subprograms are listed in the
Engraving Inscriptions operating instructions.

The subprograms and sample programs for engraving
are also saved in compressed format in the file
Grav_4290.zip in the machine “BEISPIEL” in the
“NCPS” directory. Copy this ZIP file to the NCPS
directory of other DataPilot machines and unzip it if
you want to engrave with other DataPilot machines as
well.

The compressed file with subprograms and sample
programs for engraving is also on the DataPilot CD­ROM (path: JH\DP4290\ZIP\Grav_4290.zip).

1.1 Engraving inscriptions

The C or Y axis is used for engraving. You can adjust
the size, orientation and position of the characters.

As a default, the subprograms engrave the character
strings

 on the front face: linear or polar
 on the lateral surface: linear

The momentarily valid machining plane determines
whether the C or Y axis is used for engraving:

 G17 (XY): Y axis
 G18 (ZX): C axis
 G19 (ZY): Y axis

Engraving characters strings

Program a character string according to the following scheme (in the
BEARBEITUNG section):

8 Insert a milling tool
8 Pre-position the milling tool to the beginning of the character

string

8 Call in sequence the subprograms with the characters to be

engraved

8 Retract the tool

The characters are engraved starting at the current tool
position. The reference point depends on whether the
characters are in linear or polar alignment:

 Linear: The reference point is the bottom left corner of

the character

 Polar: The reference point is the center of the bottom

edge of the character
