Well in this case, plunging would have been fine since I was cutting acrylic. However, if I would have been cutting aluminum then no, I wouldn't plunge since it would be more wear on the cutter assuming I had an center cutting endmill. The other way being to setup a different op to drill a pocket for the plunging location but again that would be another step that I could simply avoid if I could helix in. So I am not sure how your option got selected for the solution but the solution I came up with was to create an extended patch of that ledge I was milling down to. That gave it more room for a conventional helix mill in and It worked for some reason. That process added about 5 min more to my machine time but by contrast the plunging as you suggested would have added at least 15min do to the tool change. Thanks for your input however, Cheers
