4. The Create Activity dialog box appears. Click on the More >> button to see the Station Activity Attributes. Change the Name to Station 1 and click on OK. Create another activity and name it, Station 2.

When you insert a station activity in the PPR tree, it will always be a successor to another station activity or a child of the main process. Stations activities children are other activities; it cannot be a child of, say a clamping activity.

5. Using the commands in the Activities toolbar to create the Stations (as shown). Make sure that you select the previous activity when inserting the new one. This will create your process that flows from activity to activity correctly.

6. If you do not have the proper process…

Follow the steps below to correct your process.

1. In the Data Views toolbar, select the Open PERT Chart and click on the word Process in the PPR tree.

The PERT Chart Window appears showing the Activities. Select an activity box with the left mouse button and drag it to the desired location. The position of any activity in the PERT chart can be modified after changing an activity's position, it will automatically snap to the center of the nearest grid square when the mouse button is released.

2. To see the Text in the Activity boxes, from the main menu, select Window / Tile Horizontally.

3. With a split view, when a activity is selected it highlights in both windows.

The names of the activities in the Pert Chart are easier to see….

Click on the + sign to view the activities under the stations process…

Linking or Sequencing activities in the PERT chart

The chart may be created with the links in place or it may not have the links in place. This procedure also explains how to modify existing links. The PERT chart appears below the PPR tree. Each box represents an activity. Each box can be manipulated and moved within the chart.

4. To delete the links, move the mouse over the line, and right click for the contextual menu. Select Delete. If needed, delete the links and create new ones so they match the process flow.

5. To create a link between two activities, click

on the Link icon. Click in the box that you want to start the link, and then the box to link to. If no other links need to be created, click on the link command to deactivate it.

Final Process

6. Close the Pert chart when completed.

To zoom in or out, click in the window (to make it active), and select the mouse functions for zooming…

x12 Fastener Assignmt welds.doc 1 of 3 Copyright DELMIA Corp. 2004

This procedure describes how to assign and view welds in a process welding activity, thereby managing and validating these Weld points well in advance of production.

In this exercise, the DPM Fastener Process Planner workbench will be used to assign the welds.

1. In the PPR tree, under Station 1, select SpotWelding 1.

2. In the Fastener Management toolbar, select the Assign fasteners from Product to an Activity command. In the PPR tree Products list, select Assembly Joints under the RH Body Side Assembly.1.

Fastener Assignment

If there is no welds showing under the fasteners available for assignment, make sure in the Tools / Options / Digital Process for Manuf / DPM – Fastening Process Planner / Commands / Activate Part Loading Constraints is deactivated.

3. The Fastener Assignment dialog box appears. This displays the total number of welds and what activity the welds are assigned. At this point, no welds are assigned. Notice that there is a pull down window for in the List of Products with Fasteners and for the List of activities. Hold the Ctrl key down and select the Welds 1,3,5. Use the arrow to assign them to the selected activity.

Welds are assigned and no longer available unless Allow Duplicate Weld Assignment is toggled on. (This is in the tools / options / Digital Process for Manufacturing / Commands) This would be toggled on if a parallel process were also being created. Welds can also be

assigned depending on what parts have been loaded prior to the welding activity selected in the Process. Apply Part loading Constraints must be toggled on for this to take effect. We will not be using that function.

4. With the Fastener Assignment dialog box still open, select Station 1 >Spot Welding .2 from the List of activities or the PPR tree.

5. Select welds 07, 09, 11, and 13 and click on the arrow to move the welds and assign them to selected activity. At this time select the accountability tab and confirm that the odd welds have been allocated.

6. Notice that, while assigning welds the weld names appear in the 3D view when they are selected, they change color. Close the Fastener Assignment dialog box when finished.

Weld Information or Weld ID

7. To continue to view the weld names, position the geometry conveniently in the 3D view. Select the Show Weld ID in 3D window button. Expand the ProductList in the PPR tree and select the RH Body Side Assembly. A weld ID dialogue box comes up. Verify that the All sub-products option is checked, and the Switch is yes, (double click on the product name if it is not) This activates them on, and off using the Apply button. Click on the Apply button a few times to see them turn on and off, then when they are off, Close.

8. The Assigned Weld information in the PPR tree.

9. Collapse the RH Body Side Assembly node in the Productlist.

This procedure describes how to assign products and resources to activities within the process. There are four methods that can be used to assign products and resources to activities:

Using the Assign a Product/Resource command (Activity Management Workbench)

This method allows you to define a relation from a list of relation types at the time of the assignment

Using the Assign an Item and Assign a Resource commands (Activity Management Workbench)

This method allows you to quickly assign a product or resource to an activity, without querying for the relation type

Using the drag-and-drop method from within the PPR tree

This method allows you to quickly assign a product or resource to an activity, without querying for the relation type

Using the drag-and-drop method from the 3D viewer to the PPR tree

This method allows you to quickly assign a product or resource to an activity, without querying for the relation type

The purpose of a process and its associated activities is to transform items, which are

represented by a specific set of data. This data may refer to products, welds, other fasteners, or points to inspect. Therefore, the more generic term "item" is used throughout the

application.

Because more than one resource is often needed for a particular activity, multiple resources may be assigned to an activity.

In this procedure the robots will be assigned to the welding, loading, and unloading activities. This creates a process that can be simulated.
