Vector burn electrodes

Use the Vector Burn dialog to select the type of vector burn you want to use. Vertical-base vector burn is supported for pre-modelled electrodes.

1. Select the type of burn you require:
   • ABC burn — Select this option to create a vector burn electrode where a special holder angles the electrode relative to the part.
   • Vertical-base burn — Select this option to create a vector burn electrode that uses a standard holder, where the electrode is angled into the blank.
2. Specify how to define the electrode extraction vector using the options in the Direction area of the dialog:
   • Use an existing, principal axis:
     • +Z (default)
     • +X
     • +Y
     • -X
     • -Y
   • Select Manual to create a custom vector. You can either:
     • Enter values in A and B to define the angle of rotation of the extraction vector in XY, and the angle from the vertical, respectively. 0 degrees is down the Z axis and 90 degrees is a side-sparking operation.
     • Click to use position-entry tools to specify the vector.
     • Click to define the vector by selecting a surface, whose normal is in the required direction.
3. Drag the Simulation slider to simulate the extraction of the electrode, to check that you have defined the vector correctly. In the case where an electrode is used under an overhanging region of the part, use the simulation to check that the electrode is clear of the part when it is withdrawn.
4. Enter a value in Burn depth to specify the height of the burn region in the burn direction. You can click to calculate the dimension of the burn vector in the direction you have specified.
5. Enter a value in Vector clearance to specify the amount the electrode is clear of the part in the vector part of the motion. You can click to calculate the clearance that is required to ensure that the electrode is clear of the part.

The Total vector length is automatically calculated, and is the sum of the burn depth and the vector clearance.
