Lead-in has same feedrate as plunge?

[FrodoLoggins]

Shouldn't the tool plunge down at 50IPM and then lead in at 5IPM? Instead the tool leads in at 50IPM:

I think this is the ramp feedrate, but when you simulate and go to the details tab what does it say, lead-in?

[FrodoLoggins]

Fusion calls it a plunge:

Even though it's not plunging but leading in.

Red moves are plunge or ramp, yours is plunge, it's a vertical line followed by a vertical radius, and your feed is at 50 for plunge and ramp, so this is correct behavior it would seem.  Your feed height is 0.1" above model, so it plunges, exactly like you instructed it to.

[FrodoLoggins]

If the tool isn't plunging the tool should not be moving at a plunge feedrate. Simple as that.

An arc perpendicular to the floor is a lead-in, not a plunge and not a ramp.

If I lower my feed height that doesn't stop the tool ramming into the stock:

It's not really as simple as that hehe.  If it's a red move, it's either plunge or ramp.  If you want that arc to be a lead-in, you need to change your feed height to be lower, and the vertical arc will become green and feed at lead-in feed.  But because your feed height is higher, it considers it a plunge move.

I can make my feed height only a thou above the bottom height that arc is still 50IPM. And I get a warning about the feed height being too low. Should I try lower than that?

[DarthBane55]

haha, I'm starting to feel the sarcasm.  I'll step out.

[FrodoLoggins]

Nope I literally set my feed height to .001" above the bottom height. Fusion still treat a lead in arc as a plunge
