Creating a Prismatic Rework Area for Corners and Channels

You can create prismatic rework areas features to rework corners and channels. This way, corners and channels are quickly identified and then reworked using different operations.

This task shows you how to:

Before you begin:
  • In our example, we have created a Pocketing operation to rough cut the part.

Creating a Prismatic Rework Area for Corners and Channels with the Legacy User Interface

  1. Activate the Manufacturing Program and click Pocketing in the Prismatic Machining section of the action bar.
  2. Click red Bottom in the sensitive icon then select the pocket bottom in the 3DEXPERIENCE platform.


  3. Go to the Tool tab to select a tool.

    See Assigning a Tool Element to a Machining Operation

  4. Select the Macros tab to specify a Return in a Level macro with linear Approach and Retract paths of 50mm.

    See Defining Macros on Milling Operations

  5. Simulate the tool path in video mode to verify the Pocketing operation.
    The pocket is rough cut by this operation.

  6. Rename the operation into Rough Pocketing then click OK to create it.
  7. Click Prismatic Rework Area .
  8. Click Load From then select the Pocketing operation Rough Pocketing that you have created.

    You can rename this feature, for example, ReworkPocket.1.

    The Rework feature is initialized with the geometry and other characteristics of the defined operation.

    Note: Profile Contouring machining operations with multiple contours are supported by newly created rework areas. Previously existing rework areas created from Profile Contouring machining operations with multiple contours are not automatically updated. Run the Load From command on those rework areas to update them

  9. Click Parameters to view the Prismatic Machining Area features parameters.
    The Machining Area Parameters dialog box appears.
  10. Click Compute to visualize the areas to rework, then OK to validate and exit the dialog box.

    The following figure illustrates the 6 corners and the channel to rework.



  11. Click Pocketing to create an operation to machine the channel left by the first operation.
    1. Select the ReworkPocket.1 feature from the list in the Geometry tab.
      The dialog box is then updated with information from the feature.
    2. Choose Channel from the Filter on Rework Area Type list.
    3. Select a tool with a nominal diameter = 10mm.
    4. Select the Strategy tab and define the Overhang value as 100.
  12. Select the Macros tab to specify:
    • An Approach macro with linear approach path of 50mm.
    • A Return in a Level macro with linear approach and retract paths of 50mm.
    • A Retract macro with linear retract path of 50mm.
  13. Simulate the tool path in video mode to verify the operation.

    The channel is machined.



  14. Rename the operation (for example, Channel Rework) then click OK to create it.
  15. Click Profile Contouring in the Prismatic Machining section of the action bar to create an operation to machine the corners left by the first operation.
    1. Select the ReworkPocket.1 feature from the list in the Geometry tab.
      The dialog box is then updated with information from the feature.
    2. Select a tool with a nominal diameter = 5mm.
  16. Select the Strategy tab and set:
    • Overhang for Rework Areas to 100
    • Distance between paths to 2mm.
  17. Select the Macros tab to specify:
    • An Approach macro with a 50mm linear approach path.
    • A Return in a Level macro with 50mm linear approach and retract paths.
    • A Retract macro with a 50mm linear retract path.
  18. Simulate the tool path in video mode to verify the operation.

    The corners are machined.



  19. Right-click to rename the operation (for example, Corner Rework) then click OK to create it.


    Note: This task illustrates the Load From capability in which the Rework feature is initialized with the geometric and other characteristics of a machining operation.
    • You can also specify the characteristics of the Rework feature manually by means of the Prismatic Rework Area dialog box.
    • This capability is used with Pocketing and Profile Contouring (except in By Flank Contouring mode) operations.

Creating a Prismatic Rework Area for Corners and Channels with the 3DEXPERIENCE User Interface

  1. Click Prismatic Rework Area from the Prismatic Machining section of the action bar.
    The Prismatic Rework Area workflow appears in the work area.
  2. Follow the instructions to create a prismatic rework area.

    A Prismatic Rework Area entity is added to the Manufacturing Program.

    The Prismatic Rework Area dialog box appears.

  3. Click in the title bar of the dialog box to edit the name of the manufacturing pattern, such as PrismaticReworkArea.x.
  4. Optional: Click New Feature to apply a prismatic machining area feature.
  5. In the Mandatory section, verify the mandatory input parameters.
  6. Optional: Do any of the following:
    1. Click to remove the input parameter.
    2. Click to display additional information on the parameter in the work area.
    3. Click to display the parameter's context menu.
  7. In the Optional section, verify the optional input parameters.
  8. In the Parameters section, verify additional parameter inputs.
  9. Optional: Click Compute Rework Area to visualize the areas to rework.
  10. Optional: Click Load From to initialize a Rework feature with the geometry and characteristics defined in a previously specified operation.
  11. Click OK to validate and exit the dialog box.
