To specify the electrode holder

Use the Specify Electrode Holder page to specify a holder to hold the electrode base.

1. Choose a catalog from the Holder Catalogs list. The default catalog for the current blank is selected if one is specified.

   To set up your own catalog of holders, contact technical support.

2. Choose an option from the Base Holder list, to specify the holder that clamps directly onto the blank. The default holder for the current blank is added if one is specified.
3. To specify a holder that fixes to the base holder during the machining process, choose an option from the Machining Holder list.
4. To specify a holder that fixes to the base holder during the EDM process, choose an option from the EDM Holder list.
Note: Select the options next to each list to change what is displayed in the viewer on the Electrode Wizard.
5. Specify the attachment point of the holder to the base. You can either:
   • Enter coordinates in X, Y, and Z, to specify the position of the attachment point relative to the active workplane.
   • Click to use the centre of the electrode base as the attachment point. This is the default position, and this option is unavailable if the default is already being used.
   • Click to use the X and Y values of the electrode datum. The Z value is defined as the top of the base, ensuring correct contact between the holder and base. This option is unavailable if the attachment point is already centred on the electrode datum.
   • Click to use position entry tools to specify the attachment point.
   Note: The holder datum takes precedence over the electrode datum. Therefore the attachment position you define for the holder will affect the datum included in the Electrode setup sheet and EDM data-transfer files.
6. Click to rotate the selected holder by 90 degrees relative to the blank. This adjusts the C angle used during electrode burns. The current C angle value is displayed below the button. If the base holder is selected, the base holder rotates. If a machining or EDM holder is selected, both the selected holder and the base holder rotate.
7. For holders from user-defined catalogs, you can click / to change between displaying a graphic of the selected holder, or a text description of the holder, in the lower right window of the Electrode Wizard.
