Engraving (CYCLE60)

Function
The "Engraving" function is used to engrave a text on a workpiece 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".
Engraving uses a proportional font, i.e., the individual characters are of different widths.
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction
2. The tool moves to the machining depth FZ at the infeed feedrate Z1 and mills the
344
plane and adjusts to the safety clearance.
