NX Thread Milling Multiple Holes Using the Same Tool when Thread Pitch Values are Different

A part has multiple threaded holes. These holes have different Thread Pitch values. Since the tool only cuts one thread at a time is it possible to mill all of these threads using the same tool? Only one tool will need to be setup on the NC machine if possible.

Solution

1. The (P) Pitch setting for the Thread Mill Tool is set to a value and the Form Type is set to Metric.



2. When the Thread Mill operations are generated with this tool the message below is displayed.



3. This occurs because the specified tool Pitch does not match the Pitch in every operation.



4. Change the Thread Mill Form Type to the Partial Profile 60 option. With this Form Type selected the (P) Pitch will be entered as the maximum pitch size that the tool is able to cut.



5. When the operations are generated no errors are reported and all paths are correctly cut. Setting the (FL) Flute Length to match the (P) Pitch  will automatically machine the thread using a Continuous Cut pattern.
