Wire EDM - Start Points
There are 2 solutions to this.
Firstly we can specify a Pilot hole (location to start the wire
threading) by using the Options tab on the Goround dialogue box.
This will create a new start position for the wire. So the sequence of
events will be.
- Machine starts at XY zero
- Rapid to Pilot hole
- Stop, Thread wire
- Start machining from the pilot hole onto the profile (set by the lead in/out tab) using the settings under the Approach tab
- Machine profile
- Return to Pilot hole
- Cut wire
- Start – machine will rapid back to XY zero
The second method is to create your own Pilot hole positions on the
drawing, see this video for details.
