Scenarios

This describes the Scenarios of Simulation Machining.

Thumbnails:

  • Collision Checking This is used to analyze collisions. Right-click to display the context menu:
    • Definition: See Machining Scenario Dialog box
    • Set as Current: See Scenario Commands
    • Simulate and Generate Results:
      • Machining simulation on simulation objects can be run directly from the 3DSearch window. For more information, see Physics Simulation User's Guide: Static Study: Performing Simulations: Running Simulations from a 3DSearch Window.
      • Selecting Run from the context menu starts a batch run of all scenarios in the simulation object. Intermediate simulation states and fault results are saved to the object at the end of the simulation. You can continue to work on other contexts, or even within the same context without modifying its content while the simulation is running. Once the simulation is over, you can open the context and work on any activity without having to update intermediate simulation results.
      • See Scenario Commands.
    • Delete: See Common Thumbnail Commands
    • Properties: See Common Thumbnail Commands
  • Technological: The probe is activated; and is used to analyze technological parameters. Right-click this for the context menu (this is the same as Collision Checking).
  • Trajectory Checking: No probes are activated as this is used to analyze the tool path (or ISO code) trajectory. Select Play, the simulation is launched on the Part Operation level. Right-click for the context menu (this is similar as Collision Checking). Machining scenarios contains dedicated parameters and is edited by right-clicking the Trajectory Checking thumbnail, and select Properties. See Machining Scenario Dialog box.

Probes

This describes the Probes section for Machining Simulation. In Machining the design, stock, and fixtures must be defined as separate 3DParts, since objects are analyzed for collision at this level.

You can use the Thumbnails to specify the types of clash probes.

Clash Machine

The machining probe detects a clash between a machine against other components. The mode Interrupt is available on Clash Stock and the machine; if selected it stops the simulation when a collision is detected. Right-click the thumbnail to:

The Clash Machine Definition dialog box allows you to specify which clash pairs to apply to a scenario. From this dialog box, you can:

Activate or Deactivate Clash Detection Pairs
Activate or deactivate clash detection pairs on:
  • Tool parts;
  • Tool machine beds;
  • Tool fixtures;
  • Machine head parts;
  • Machine head machine beds;
  • Machine head fixtures;
  • Machine head stock.
You can also activate or deactivate clearance mode for each of these parameters. If a clearance mode is activated, you can define a Clearance value as:
  • A positive value reports a message when the components come near each other within the specified value.
  • A zero value reports a message if the components come in contact.
  • A negative value reports a message when the components collide within the specified value.
Note: When the clearance mode is activated with a positive clearance value, the fault is reported in the Fault List as a Clearance with this specific icon . The faults can also be filtered by clearance.
Define Custom Clash Pairs
Expand the Define Custom Clash Pair panel to create, modify, or delete custom clash pairs. All custom clash pairs are listed in the list.
You can select to create a custom clash pair. You can also enter a name in the Custom Clash Pair Item field. Clicking Add allows you to select products in the work area, Delete removes products from the clash group. Clicking Apply saves the custom clash pair and adds it to the list of clash pairs displayed in the dialog box.
Select a clash pair item from the list to modify it. Clicking Delete deletes the clash pair.

Clash Stock

Detect clashes between stock and other components, such as tools and tool holders. Right-click the thumbnail to specify:

  • Add to Current Scenario (Highlight): For more information, see Probe Commands.
  • Add to Current Scenario (Interrupt): For more information, see Probe Commands.
  • Delete: See Common Thumbnail Commands.
  • Properties: Describes the properties.
  • Definition: Opens the Clash Stock dialog box.

The Clash Stock dialog box allows you to specify gouge and clash volume parameters. From this dialog box, you can:

Detect Gouge
Select to detect gouges and define the Gouge Tolerance. The Gouge Tolerance is defined as 0.05mm by default, all gouges smaller than this value are not detected.
All gouges are displayed in the Fault Type list, and are sorted accordingly. For more information, see Fault Type.
Compute Clash Volume
Select to compute the clash volume and define a minimum acceptable gouge volume to filter false positive clash detection. The Min Acceptable Gouge Volume is defined as 0.00mm3 by default.

Technological

The machining probe measures technological parameters. Right-click the thumbnail has similar selections as New Machining Clash Probe .

Results

This describes the Results of Machining Live Simulation.

This shows you the results of various scenarios.

Right-click the thumbnail. The context menu appears showing:

  • Set as Current: Specifies the thumbnail to the current one.
  • Simulate and Generate Results: Run a scenario, any results that are generated are then persisted in the simulation object. These results can then be retrieved from the results tab page in live simulation, using the context menu item View Scenario Clash Results.
    Note: This starts a simulation at Part Operation level, it is impossible to generate results only on an operation or program.
  • View Scenario Results: Selecting this, the View Results of Technological dialog box appears after Simulate and Generate Results is run The specifications show you the Technological/Volumetric flow of material removed.
    • The Plot tab displays the 2D curves of the selected parameters.
    • The Table tab, lists the Time and Volumetric flow so you can export the data.
  • Export Animation Exports the Animation.
  • Swept Volume Creates a Swept Volume. See VPM Collaborative Platform | Virtual Product Modeling | VPM Volume Computation | Creating Swept Volumes | Creating Swept Volumes
  • Analyze Scenario Stock Result: After Simulate and Generate Results with operation Material removal activated the final stock is stored and persisted into the scenario results. Here you can access the stock results in a new window.

  • Export Scenario Stock Result: The Create Video Result dialog box showing where you can select the Existing Part and the New Part.
  • View Scenario Clash Results: See Collision Fault List This is displayed by highlighting the collided path on red and display a red cross in the 3D where the parts are clashing.

  • Properties: Shows the properties of the selected item.
