DIN PLUS (Y Axis): Milling Cy
cles
Engrave in YZ plane G804
G804 engraves character strings aligned linearly in the YZ plane. The
text to be engraved is entered in the “ID” box as a character string.
Diacritics and special characters that you cannot enter in the DIN
editor can be defined, character by character, in “NS.” If text is
defined in “ID” and a character is defined in “NS,” the text is engraved
before the character.
G804 starts engraving from the starting position or from the current
position, if no starting position is defined.
Example: If a character string is engraved with several calls, define the
starting position in the first call. All other calls are programmed without
a starting position.
Character table: see User’s Manual.

X Milling floor (diameter). X position, infeed depth during milling.
I Retraction diameter. X position retracted to for positioning.
H Font height. Height of the characters in [mm]
W Position angle of the character string. Examples:
„ 0°: from –Y to +Y
„ 90°: from –Z to +Z (see figure)
E Distance factor. The distance between the characters is
calculated according to the following formula: H / 6 * E
F As of software version 625 952-05:
Approach feed factor (feed rate = current feed rate * F)
