Define a Straight-Line Cutting Path
You can define a simple, straight-line path for the cutting operation.
-
From the Additive Manufacturing section of the action bar, click Cutting
.
-
Select the part.
The part indicates the predefined volume (part or mesh) that contains the elements that you want to remove with a cutting operation. This part must contain elements that were previously activated in the same analysis.
-
From the Point input mode options, select one of the
following:.
Option Description Support Selects a point from the geometry, publication, or node group. Specify Orients the local feature triad directly. Right-click the feature triad glyph on the model, and select an orientation tool.
-
From the Axis system definition options, select one
of the following:.
Option Description Global Aligns the local feature triad with the global coordinate system.
Local Aligns the local feature triad with a selected axis system in the model.
Specify Orients the local feature triad directly.
Right-click the feature triad glyph on the model, and select an orientation tool.
The U|X direction of the selected axis system defines the cutting line direction.
- Specify the Length of cut line.
-
Specify the Cutting time.
The cutting time defines the time period for the completion of the cut along the entire cut path. Cutting operations, like the original additive manufacturing, can induce thermal stresses. These are usually reduced if the operation is slow.
-
From the Bead position options, select one of the
following:
Option Description Below Positions the cutting bead below the cutting line, extending down to the specified bead height. Above Positions the cutting bead above the cutting line, extending up to the specified bead height. Middle Positions the cutting bead on the cutting line. Half of the bead height is above the line and half is below. -
Specify the Bead height.
The default bead height is the average element size.
-
Specify the Bead width.
The default bead width is the width of the entire model.
-
Select Follow deformation to have inactive elements
follow the model deformation.
Inactive elements are elements within the part volume mesh that do not contain enough material to be activated.
-
Optional: Edit the Expansion time
constant.
The expansion time constant ramps down the selected thermal strain at element deactivation. The default constant is two times the initial time increment in the static step.
-
From the Deactivation type options, select one of
the following:
Option Description Full Deactivates entire mesh elements when their volume is less than the Min volume fraction. Partial Partially deactivates elements when their volume is less than the Deactivation Threshold and fully deactivates them at the Min volume fraction. -
Enter the Deactivation Threshold as a fraction.
The deactivation threshold applies partial deactivation. For example, you could partially deactivate an element at 0.95 (95%) fill to begin simulating that area of the part.
-
Enter the Min volume fraction.
The minimum volume fraction applies to both full and partial deactivation. The minimum volume fraction is the amount of fill at which an element is treated as completely empty of material. For example, you could treat all elements with less than 0.10 as empty.
