Explanation of Vertical Lead-In Radius for those in Domino class

Hello. During the Haas Part 1 class - we got to the Pocket slides and one note we had was to set the Vertical Lead-In Radius = 0 in the linking parameters for the pocket else it would not work and the HAAS would stop. I said I would look into this and here is the explanation:

The G code generated with this option set to non-zero is that it generates a G19 code which is not used much and which is a circular interprolation around the X axis. That means it’s trying to lead-in in a circle down and under the table and back around. Not gonna happen. This option is most likely for a 4 or 5 axis machine. The fix is simple as Walter has set in his slides - SET TO ZERO. Code G19 is not generated and all works. Just something to keep in mind in your programming. It may sound all technical and complicated, but just SET TO ZERO.

Cheers!
