Part library example

FeatureCAM has a Counterdrill hole. These are the manufacturing steps:

  1. Spot-drill the top.
  2. Drill the smaller diameter hole.
  3. Drill the top diameter hole.

The order of these is fixed, you cannot rearrange them in the Op List.

An alternative manufacturing strategy would be to:

  1. Spot-drill the top.
  2. Drill the larger hole on the top.
  3. Drill the smaller diameter.

You can use the part library to create a feature that uses the alternative manufacturing strategy.

  1. Create a plain hole:
    1. Set the Diameter to 0.375.
    2. Set the Depth to 0.25.
    3. On the Strategy tab, select the Spot drill and Drill options.
    4. On the Location tab, set the X, Y, and Z coordinates to 0.0.
  2. Create a second plain hole:
    1. On the Dimensions page, set the Diameter to 0.25 and the Depth to 0.75.
    2. On the Location page, set the Z location to -0.25
    3. On the Strategy page, deselect the Spotdrill option and select the Drill option.
  3. Create a group of the two holes:
    1. Arrange the holes so that the top hole is the first in the group.
    2. Select the Ordered option.

Select the group and create a library part.
