12.6 ENGRAVING (Cycle 225, DIN/

ISO: G225)

Cycle run

This cycle is used to engrave texts on a flat surface of the

workpiece. The texts can be arranged in a straight line or along an

arc.

1 The TNC positions the tool in the working plane to the starting

point of the first character.

2 The tool plunges perpendicularly to the engraving floor and

mills the character. The TNC retracts the tool to the set-up

clearance between the characters when required. At the end

of the character the tool is at the set-up clearance above the

workpiece surface.

3 This process is repeated for all characters to be engraved.

4 Finally, the TNC retracts the tool to the 2nd set-up clearance.

Please note while programming:

The algebraic sign for the cycle parameter DEPTH

determines the working direction. If you program

DEPTH=0, the cycle will not be executed.

If you engrave the text in a straight line (Q516=0),

the starting point of the first character is determined

by the tool position at the time the cycle is called.

If you engrave the text along an arc (Q516=1), the

arc's center is determined by the tool position at the

time the cycle is called.

The text to be engraved can also be transferred with

a string variable (QS).
