Marking and deleting drilling ranges

This procedure belongs to step 4 of the simple nesting workflow.

  1. Position your objects horizontally and vertically in the top view.
  2. Rotate your objects about the Z-axis in the top view.
  3. Check if all cavities and drillings are correct.
  4. Specify the drilling range for objects with unrecognized drillings.
  5. Mark the cavities for objects with unrecognized cavities.
  6. Set bars for all objects.

This procedure belongs to step 7 of the complete nesting workflow.

  1. Delete any incorrect machined areas.
  2. Change the status of objects and delete non-required objects.
  3. Position your objects horizontally and vertically in the top view.
  4. Rotate your objects about the Z-axis in the top view.
  5. Adjust the height position of your objects and/or rotate them about the X/Y-axis (required for multilayered blanks).
  6. Check if all cavities and drillings are correct.
  7. Specify the drilling range for objects with unrecognized drillings.
  8. Mark the cavities for objects with unrecognized cavities.
  9. Create a sinter bar for objects that require a sinter bar.
  10. Set drops for objects that require drops.
  11. Mark the attachment for objects with an attachment.
  12. Activate anterior tooth editing for the desired object)
  13. Edit or delete labels milled on objects.
  14. Set bars for all objects.

If an object contains an unrecognized or incorrectly recognized drill hole, you must manually specify the drilling range via the corresponding editing function. Otherwise, the object will not be machined correctly. This function also allows you to specify angled drillings.

Check all drilling ranges of all objects in your blank for proper marking.

Checking drilling ranges and cavities for proper marking

Before you can correct markings of drilling ranges, you need to delete the incorrect marking.

  • Open the Nesting view for adjusting objects with the following icon in the main icon bar:

Deleting and marking drilling ranges in the nesting view for adjusting objects

Deleting drilling ranges

  1. (Optional) Select the desired object in the blank display.

    • DentalCAM highlights the object in the object list with a colored border.

     

  2. Open the editing functions for the required object by selecting the following icon in the left column: 

    • The icon bar for the editing functions is displayed.

     

  3. Open the editing function for marking drilling ranges by selecting the following icon:

    4. Opening the editing function for marking drilling ranges (icons marked orange)

    • DentalCAM displays a list with all marked drilling ranges in the left column.

    A list of all marked drilling ranges for 1 object

  4. To find the desired drilling range in the list, select the corresponding arrow which indicates the drilling direction in the blank display.
    • DentalCAM marks the selected drilling range in the list with a blue border.

  5. To delete the drilling range, select the following icon:
    • DentalCAM removes the entry from the list and the visual representation of the drilling range in the blank display.
  6. Manually mark the drilling range. Otherwise, the drill hole will not be machined correctly.

  7. Save your changes with the lower arrow icon:

  8. Close the area for the editing function with the upper arrow icon:

Marking drilling ranges

  1. (Optional) Select the desired object in the blank display.

    • DentalCAM highlights the object in the object list with a colored border.

     

  2. Open the editing functions for the required object by selecting the following icon in the left column: 

    • The icon bar for the editing functions is displayed.

     

  3. Open the editing function for marking drilling ranges by selecting the following icon:

    4. Opening the editing function for marking drilling ranges (icons marked orange)

    • The icon bar for marking drilling ranges displays in the left column.

    1. Icon for starting the workflow
    2. Icon for setting measuring points
    3. Icon for specifying the diameter of the drill hole
    4. Icon for completing the workflow
  4. If the object has any incorrectly marked drilling ranges, delete them.
  5. Start the workflow by selecting the following icon in the left column:
  6. Move the view so that you look into the drill hole from above. You must be able to see a good portion of the wall of the drill hole.

    7. Positioning the view to view the bore wall

  7. Continue by selecting the following icon in the left column: 

  8. Set 3 measuring points on the wall of the drill hole with a mouse click

    • The points must lie on an imaginary auxiliary line which is perpendicular to the direction of the drill hole.
    • Space out the measuring point slightly, but not so much that you have to move the view.
    • For drill holes with a connection geometry, position the measuring points on the wall of the drill hole and not in the connection geometry.

    9. DentalCAM may re-position your measuring points. As long as all points still lie on the wall, everything’s fine.

    • As soon as you have set the 3rd measuring point, DentalCAM switches to the top view so that you can check the position of the measuring points.

    The measuring points from top view

  9. Continue by selecting the following icon in the left column:

    • DentalCAM displays a value bar for the diameter of the drilling range in the left column.

  10. Determining the diameter of the drilling range Increase or decrease the diameter of the drilling range with the value bar.

    • For many objects, the diameter must be slightly larger than the opening surface of the drill hole.

    • If the object has a connection geometry, make sure that the entire connection geometry is marked as a drilling range.

    11. Specifying the drilling range

    Correct diameter for a standard drill hole

    Correct diameter for the drill hole for an abutment with a connection geometry

  11. Finish the workflow by selecting the following icon in the left column:
    • DentalCAM draws the drilling direction as a green arrow and the drilling range as a green surface.

    A successfully specified drilling range

    A successfully specified drilling range for an abutment with a connection geometry

  12. If the arrow is displayed in red, the drill hole is too angled for machining in the machine. In this case, try the following:

    Example: Drill hole too angled

  13. Make sure that the drilling range covers the opening surface of the drill hole. The result will not always be as optimal as in the example above because STL files have a finite precision.

    However, if some parts of the marking do not cover the drilling range or if the opening surface is bent, you should delete the drilling range and mark the drilling range again.

  14. Mark the opposite end of the drill hole.
