Nikcole Mini System
#11
Hello Wrustle,
I do get your point about using a tip narrow enough that the second cut consumes at least a half of the tip face but it is exactly the opposite of what I was taught, 20+ years ago using Kenna metal tooling on Okuma cnc lathes.

My teacher's and the Kenna metal rep's theory was the thicker tip was less likely to deflect or break under the side loading.

I'm guessing both ideas have their pros and cons, the kenna metal guy was pretty adamant though that using the right size was the right way, but as we all know the tips don't come in 0.001" incremental sizes but design engineers draw the grooves any size they might want to.

As it happens I use the tip that I either; have, or the one that is in the tool at the time, as long as it is smaller than the groove size and it always works out Ok,

My suggestion for reducing the tendency for tapered groove sides should they occur is to reduce feed rate when widening grooves.

regards Rick

PS I'm not trying to be contrary, but offering a different experience for discussion.
Whatever it is, do it today, Tomorrow may not be an option and regret outlasts fatigue.

Inserts have changed a lot in 20 years. It's good to hear of others experiences though.

Anthony,

I'm pleased with the tool. I got it mainly for grooving so that's all I've used it for and it works well.
