Speeds and Feeds are important they are even more important when using insert cutters.
Luckily the manufacturers have helped here often they have data available regarding speed, feed, depth of cut and the material  being cut for particular inserts.

However if I where you I would just ask Ken   this guy lives and breathes inserts heck he evens dreams about them in his sleep  
You will have to give him some criteria.
Such as: Your machine, whether you want  speed and feed so as not to stress the machine (and you ). If you require the inserts to last as long as possible - this will mean TIME (cutting time) is not your main or prime concern.

Ken will come up with some parameters for you, Speed, Feed, Depth of cut. It will be a whole lot better than a 'thumb suck'.

Hello DAVE
Thanks for this
Will definitely ask KEN
Read your recommended article. Thoroughly enjoyed it and I must say, it was a real eye opener.

Setting SPEED is a straight forward choice where one would follow a given set of numbers and work therefrom.
However, FEED on the other hand is really an elusive mirage.

Hear me out.
What both U and Ken have correctly and scientifically elaborated on is for us rookies, really an academic presentation. To implement that specific feed rate is well nigh impossible, unless one's machine has, a SPEED METER or maybe a DRO ??? Never heard of that !!!
Don't know if a DRO gives movement/momentum Rates or the like ???
How would one really know practically, even using an Auto Feed, that the Table is Travelling at a specific speed into the cut ???
There is no way to measure that on our Home Shop Machines.
Yes, we concede, even so called High Speed High Feed Cutters have their limitations, as we have just experienced. But to be able to precisely measure our FEED, that is subjective and argumentative. Yes, we can control that Feed Rate within certain given parameters, but no way Sir, can we measure that. Like U mentioned, either the Cutter or the machine will tell one that all is hunky dory or otherwise.

Please, do take this in the vein it is intended. We do not want to disprove what U Folks are saying. On the other hand, we totally agree as we have lesser knowledge and experience by eons. We reiterate, we want to thoroughly understand our machine and utilise the Tool invested in to its full potential.
