Bevel cut
The bevel cut function enables the manufacture of beveled cutting edges with an angle of 1° to 50° on the sheets. This enables the preparation of welding edges and the insertion of countersinks on the 2D laser machine.
| The bevel cut function is only available for the TruLaser 3040/3060/3080. |
TC_LASER_MACHINING_ON
The laser beam is ignited with the TC_LASER_MACHINING_ON cycle in the NC program.
TC_MACHINING_LASER_ON(laser method,"technology table",piercing type,cutting type)
-
Is programmed at the start of each contour machining.
TC_LASER_MACHINING_ON(1,"ST030MD0-N2SB-30-2","PIERCE-10","BEVELCUT-100")
| Parameter | Value | Description |
|---|---|---|
Laser method |
1 |
Piercing and cutting with distance regulation. |
Technology table |
ST030MD0-N2SB-30-2 |
Name of the laser technology table. |
Piercing type |
PIERCE-10 |
Normal piercing. |
Cutting type |
BEVELCUT-100 |
Bevel cutting large contour, normal cutting speed and normal acceleration. |
TC_TRAFO_ON
The TC_TRAFO_ON cycle activates the axis transformation required for the bevel cut. This unlocks the locking unit of the rotary axis.
TC_TRAFO_ON
-
Self-holding (modal) operation.
-
Must be programmed before the TC_LASER_MACHINING_ ON cycle.
-
Is deleted by TC_TRAFO_OFF.
