Cut Lifter : Options and Results

Access: Open this function from one of the following locations:

Select Mold Design > Lifter > Cut Lifter from the menu bar.
Select Lifter > Cut Lifter from the Mold Design Guide Toolbar.

Cut a lifter by active and parting surfaces.

After adding the lifters, the placed lifters are automatically cut and the system creates the relevant pockets in the core and cavity.

Required Step 1

Pick the component to be cut.

The following parameter is displayed:

Target Part

This parameter displays the name of the selected component.

The parameter is displayed in red when it is empty (before a part is picked or if you clear the selection). After a part has been picked, the parameter is grayed out and displays the name of the selected component. For example:

Before picking the target part.	After pick the target part.

Note: After selecting the component, the next step is automatically displayed. You can view the grayed out Target Part label (with the name of the selected component) by re-entering the first step in the function.

When the required component has have been selected, the system displays the next step in the function.

Required Step 2

Pick at least one face (see the options below) to cut the lifter; the selected face should be fully or partially contained by the component body.

The following parameters are displayed; to improve clarity, the components selected in step 1 are displayed in wireframe mode in this step.

Set the parameters.

Auto Cut

This is a toggle option Auto Cut / Cut By Selection that enables you to control the faces cutting the selected lifter.

Parameters:

Auto Cut

Cut the component by the selected QuickSplit face(s). The system automatically selects all additional relevant cutting faces.

Pick at least one QuickSplit face that is fully or partially contained by the lifter selected to be cut. The system then automatically selects any additional relevant faces (fully or partially contained by the lifter) with which to cut the lifter.

Cut By Selection

Cut the component by the selected QuickSplit face(s). Manually select any additional relevant cutting faces.

Pick at least one QuickSplit face which belongs to the work part or from a part under the "Parting Surface" sub-assembly, that is fully or partially contained by the lifter selected to be cut. If at least one QuickSplit face was selected, the Analyze Cut parameter becomes available (this parameter is initially grayed out).

Press the Analyze Cut parameter to highlight any additional relevant cutting faces (fully or partially contained by the lifter) and then manually select these faces as required.

Note: The selected face(s) must be active and fully or partially contained by the lifter component body.

Max. Gap

This parameter controls the cut tolerance.

The initial default tolerance value is as defined in the Preferences. See the same Preference also for the tolerance range.

Cut / Import

This is a toggle option Cut / Import which determines whether the components selected in step 1 are cut or have a face imported to them.

Cut

The system automatically detects all the required faces to cut the lifter. The components selected in step 1 are cut by the faces selected in step 2. This is the default option.

In this case you need to indicate the side to be removed by using the directional arrows. You can flip the direction by clicking the arrow.

For additional cut operation information (cases of cut failure) see the Cut Operation Details notes of the Cut Active function.

Import

The faces selected in step 2 are imported to the components selected in step 1.

Include All Parting Faces

This is a dropdown list that enables you to detect with which faces to cut the lifter.
The following options are available:

Include All Parting Faces	Detect with which faces to cut the lifter; this option considers ALL parting faces which are inside the lifter.
Include Parting Faces Attached to Same Direction	Detect with which faces to cut the lifter; this option considers only parting faces with a parting attribute of the relevant (picked face) split directions.
Ignore Parting Faces	Detect with which faces to cut the lifter; this option ignores any parting face.

Create Full Preview

Create a full preview showing the result of the Cut Lifter operation, based on the selected faces and the above parameter settings.
This parameter is grayed out until at least one face is selected.

Start Open Edge Analysis

This parameter is displayed if Cut By Selection was used and at least a single face was selected.

Analyze and show the open edges on the selected parting faces by marking them in yellow.
This option helps you to detect if there are any problematic areas.
ExampleExample:

Optional Step 1

Cut by undercut extension. Pick the cutting faces.

This option is used to identify the undercut faces (in the work file). These faces are automatically selected the first time you enter this stage. You will then be able to unselect faces or add new faces to the selection (from the work part only).

Flip the arrow direction if necessary.

The lifter is then cut by the selected faces.

Press OK or Apply in the Feature Guide to complete the function.

The components selected in step 1 are cut by the faces selected in step 2.

When completed, the Lifter Cut feature will appear in the Feature Tree as follows:

Notes:

If instances exist and may get cut by different faces, they are cut according to the first handled instance.
New split directions are created in the components cut by the work part faces. A split face attribute is assigned to any face that was created as a result of being cut with a split face in the work part.
- Components holding these faces are attributed as "active parts" and are displayed in the Parting Tree.
- The new split direction has the same direction and color as the parent split direction in the work part.
