Ooo man believe me, you don't want any advice on feeds/speeds from me. I'm that guy that usually goes by feel/ear/sound/shape of the chips.

There is a sea of information , if you want to research . Other this and the many many rule of thumbs (which differ from man to man) , you can find relevant info in tool catalogs , online catalogues , also usually on the box of the inserts . 1 tip if you're working with a small , like half inch and under , don't go by the recommended depths and feed , or at least start on the low side. (a CCMT060208 might take a 2mm per side cut , with a 0.25mm feed per rev , but a 10mm boring bar surely will not especially in steel and harder metals)

Don’t understand what you need to know it’s basic simple math...all material and carbide has a number you transpose into the formula....to get your feeds and speeds then you fine tune..on the machine the cutting formula are freely available and set in stone...simple rule of thumb is the colour of the chip straw colour...which means the heat is in the chip and not the tool and it should be chip not a string.. Simple

Feeds and apeeds are going to differ via material and batches. The best thing to do is experiment. Hands on is your best instructor. I needed to edit most of my programs after they were written and loaded to the server. Had a couple hundred of them. I remember one casting would be so different batch to batch that my rough cuts could vary in speed by as much as 400rpm, and we won't even talk about the feed rates. 😂😂 Also, insert choice will affect how fast you can cut, and how long the insert will last. One tip, I always tried to only leave .010 for my finish cuts if possible. Inserts last much longer, can run the cut faster, more consistent and the finish tended to be better (for me). Loved running a cnc. Sure do miss it.

@@justinl.3587 The ratchet is for people who don’t know how to measure. When you’re measuring something, you have to feel it so you know you’re measuring it right, you can’t use a ratchet and feel the workpiece. There are probably times when using a ratchet is acceptable, but I haven’t found one yet. You see people transfer a measurement from a gauge and they just ratchet away, they could be out by 20-30 microns. I never use the ratchet, never have. I think using the ratchet might get you within 03, maybe 02, but not using the ratchet will get you within 01 or better every time.

When you face a part, if you use the constant cutting speed function (instead of the constant rotation, ore fixed rotation one) the control adapts the revs per minute of the spindle according to the position in x of the cutting tool. The smaller the diameter turned, the faster the spindle turns and vice versa. When the diameter is large, it helps you to save a lot of time.
