Use the Hole Group Parameters dialog to view, or modify, parameters for a hole group.
To display this dialog, select Part Features > New Hole Group or Part Features > Group Parametersfrom the menu bar, or double-click a hole group icon in the Face window.
When using the Hole Group Parameters dialog for milling, the following settings are available:
Through Hole — Select so PartMaker creates a through hole. When the option is unselected, PartMaker creates a blind hole.
When creating a blind hole, you can specify the type of hole using the values available in the To list box.
Major Cycle Operation
- Type — Select the type of major cycle operation, such as, Drill, Bore, or Tap.
- Diameter —Enter the diameter for the major cycle operation.
Chamfer — Enter the chamfer size.
Z_Surf (S) — Enter the signed distance from the zero point to the part surface.
Z_Rapid (R) — Enter the initial clearance required between the tool and the part surface.
Z_Clear (Cl) — Enter the distance between the bottom tip of the tool and the part surface when a tool starts feeding into the part.
Nominal Depth — Enter the hole depth for blind holes or the material thickness for through holes.
To — Select how PartMaker measures the Nominal Depth for blind holes. You can select to measure the depth to the:
- Shoulder of Major Tool.
- Bottom of Major Tool.
- Shoulder of Largest Drill.
- Tip of Largest Drill.
- Solid Model — When selected, PartMaker calculates the depth for every tool in the cycle from the surface coordinate to the surface of the imported solid model by projecting each hole position onto the solid model and checking for interference of the solid model with the tool. If there are multiple locations in the hole group, the depth for the entire hole group is the minimum of the calculated depths for each position within the hole group.
This option is available only when using a solid model in the Solids window.
Cycle — Click so PartMaker automatically selects a cycle from Cycle database according to the type and diameter of the major operation. If there is more than one cycle available, the Select Cycle dialog is displayed for you to select the cycle you require.
List of operations — This area displays the operations for the cycle selected for this group.
Edit Cycle — Click to display the Edit Cycle dialog, where you can make changes to the operations for this specific hole-making cycle.
Group Name — Enter a name for the hole group.
Verify Shape — Click to display a picture showing the appearance of the finished hole. If you have a broaching operation selected, you can view a top or side view of the finished hole. Click the Hide Shape button to close the picture and return to the Hole Group Parameters dialog.
Extract Parameters From Solid — Select this option if you want to extract data from a hole on the solid model. PartMaker uses one of two parameter extraction modes:
- Selected Holes mode — If you have any operation except Rotary Broach, Index Broach, or Keyway Broach selected, PartMaker automatically recognizes the hole when you click part of it. Select the part of the hole that you consider to be the major diameter of the hole, then click Extract to extract the data.
- Selected Surfaces mode — Select any surfaces that define the hole. PartMaker then calculates the surface and depth values when you click Extract.
Extract — Click to extract data from the model for use on the Hole Group Parameters dialog. See Extracting data from holes for a hole group for more details. This button is available when a valid surface is selected (so it is highlighted in red) on the solid model.
Undo — Click to undo any changes made to the data on this dialog when extracting data from the solid model using the Extract button.
In PartMaker/Mill, after creating a new hole group, you can use hole patterns to specify hole locations.
