Tool Life Expectations?

[Washout]

Awesome - the material removal rate is fantastic compared to the raster/offset paths I'm using out of Vetric and there's something very "right" about chips and the way they come off of the cutter.

2000mm/min doesn't sound too aggressive (I assume that's the rough maximum as iMachining varies the feed) - I was expecting 3-4000mm/min max, but as you say its No. 2 out of 8+ settings.

Well it doesn't so much change the Feed but more it adjusts the stepover when you go to higher settings.

How it works is by varying between a Minimum and Max stepover and feed rate in differant areas to maintain a constant chip load and positive tool engagement.

To give an example of going one setting higher. 8mm Carbide 11mm flute length cut depth 15mm done in 2 passes [email protected] DOC 2nd @ 6.6224mm

#2 setting
Min Step over 0.160mm Max 1.050mm feed 2411mm/min Spindle speed 13,571Rpm x 2 steps . . . . Cut time per part 3.27mins
#3 setting
Min Step 0.560 Max 1.710 Feed 2498mm/min 14,667Rpm x 2 steps . . . . Cut time per part 2.10 mins!!

My machine would have handled this and possibly higher but didn't want to push it.!

Just for giggles.
#8 Min step 2.880mm Max 3.310 Feed 3902mm/min 16.213Rpm x 2 steps . . . . Cut time per part 0.52 Mins.!!!!

This would rattle my machine into pile of nut n bolts and melt down the spindle. . Lol

Funny enough Same but with flute length to allow full 15mm DOC so only 1 x pass isn't that much quicker due to lower STO & feeds.
#2 Cut time per part 3.08 min
#3 Cut time per part 1.54 min
#8 Cut time per part 0.42 Min

Edit: Oh by the way just checked code and that video was done on setting #1 not #2 and thats why feeds are lower at around 2mtr/min. Total time for 3 parts was around 15mins I seem to remember.?
