Approach/retraction
Variable texts
5-260
The "Engraving" function is used when you want to mill a text along a
line or arc.
You can enter the text directly in the text field as "fixed text" or assign
it via a variable as "variable text".
ShopTurn uses a proportional font for engraving, i.e. the width of the
individual characters varies.
1. The tool approaches the starting point at rapid traverse at the
height of the retraction plane and adjusts to the safety clearance.
2. The tool moves to machining depth Z1 or X1 at infeed rate FZ or
FX and mills the character.
3. The tool retracts to the safety clearance at rapid traverse and
moves along a straight line to the next character.
4. Steps 2 and 3 are repeated until the entire text has been milled.
There are various ways of defining variable text:

Date and time
You can engrave workpieces with the production date and current
time of day, for example. The values for date and time are read
from the NCK.

Workpiece count
Using the workpiece variables you can assign a consecutive
number to the workpieces. You can define the format (number of
digits, leading zeroes). Die Variable „Stückzahl" ist als Anwender-
variable (_E_PART[0]) im Datenbaustein GUD 7 definiert.
The place holder (#) is used to format the number of digits at
which the workpiece counts output will begin.
If you output the workpiece count 1 for the first workpiece, you can
specify an additive value (e.g., <#,_E_PART[0] + 100>). The
workpiece count output is then incremented by this value (e.g. 101,
102, 103,...).

Numbers
When outputting number (e.g. measurement results), you can
select the output format (digits either side of the point) of the
number to be engraved.

Text
Instead of entering a fixed text in the engraving text field, you can
specify the text to be engraved via a text variable (e.g.,
VARTEXT="ABC123").
