Thank you for the confirmation.

I have a 'somewhat' related question that will highlight my current inexperience with F360 CAM, and is something I have always been unsure about.

For my M6 thread I programmed my thread mill with a 1 mm thread pitch (TP) and a pitch diameter offset (PDO) of 1.1557 mm. Am I correct in that the thread depth will be PDO/2 or 1.1557/2 = 0.5779 mm. And if my pilot hole is 5 mm in diameter, then the total thread cut width would be 5 mm + 1.1557 = 6.1557 mm?

What therefore are the differing results if I choose to have:

1) no multiple passes/stepovers?

2)  1 stepover @ 0.5mm? (total=0.5mm)

3)  4 stepovers @ 0.5mm? (total=2mm)

4)  4 stepovers @ 0.05mm? (total=0.15mm)

Does F360 give an error if the stepovers surpass what the TP/PDO values call for?

If the total stepovers I program are too small, does the last pass make up the difference called for by the TP/PDO values?

Hopefully my examples and questions make sense.
