Thank you for the content. This is the second time I have referred to your tutorials. You've really helped me... Just a little advice the next time you run a Flowline, start at the bottom, and slow down the first pass only. that way you can utilize the dia of the tool SFM rather than the ball, plunging is hard on the tool very little SFM if any, and loads up.

Your insert or mill will break at unpredictably because of plunge at each start.

flowline is for finishing ... you cant plunge like that ,maybe rough with a flat or a bull and then flowline the .01 away ,,,

He does note two use Opti rough before

My tool is not doing what it’s supposed to. Too high..where does it know start. I’m new to mastercam, using Haas VF3

I had a question. I'm trying to machine a undercut. I've been reading on forums that flow line might work? But I don't know much about flowline. Is it possible to make it machine from the top down, but at the end make the tool come back up to the starting point then move off the part? It's kind of like a wide ID slot but at the bottom of the casting there is a feature, so the too can't "lead out" at the bottom or it would machine right through the cast in feature. What I'm trying to make the program do is come down on center to my start depth (the slot is already partially started). Move into the slot and helix down to my depth. Have the tool come back up to the start depth and move back to center before ending. My apologies, I feel like I'm rambling.

are you canadian?
