Creating a Roughing Rework Operation

This task explains how to rework a part.
You must have defined a rough stock in the part operation
A rough stock that is defined in the part operation before starting the definition of the
Manufacturing Program will be used for all of the successive operations, each working
on the residual material left by the operation before it. 

You must have computed at least one machining operation prior to this one in the
Manufacturing Program.

The rough stock used for a program where you insert a reworking operation must be
topologically closed, that is, it cannot be formed by a set of faces.

Roughing rework does not function correctly if you have a rough stock in several parts
because the rework rough stock will be defined as the containment box around them.

In order to simplify the scenario, the sample given below already contains a rough stock.
  1. Open the Basic.CATProcess file.

  2. Select Rough stock in the Product list and hide it using the Hide/Show option in the contextual menu.

  3. Fully expand the Manufacturing Program.
    You will see that a first roughing operation has already been effected.
    Select that operation.

  4. Click Roughing .
    The dialog box opens at the Geometry tab .

  5. Click the red area in the sensitive icon and select the part in the viewer.
    Then double-click anywhere in the viewer to confirm your selection and redisplay the dialog box.

  6. Go to the Tool tab .
    Click and select the tool called T2 End Mill D 5 in the dialog box that is displayed.

  7. Click Tool Path Replay .
    A progress indicator is displayed.
    You can cancel the tool path computation at any moment before 100% completion.

  8. If you wish, you can modify any of the other parameters:

    in the dialog box but this is not obligatory as they all have default values.

 

Invalid Face

  1. If a tool path cannot be computed because of invalid faces,
    an explicit warning message like this one will appear:

    Each invalid face is highlighted in red, with an arrow pointing on it.

    This visualization is removed when you close the main dialog box or
    when you select Remove in the contextual menu.

Be very careful when you choose to ignore invalid faces.
We recommend that you ignore only faces that will not affect the tool path.
Otherwise this may lead to defective tool paths.
