Hi,
I had a speeds and feeds chart that came from a model engineers web site. Unfortunately, I've lost it. I know that I can work it out with surface feet per minute, but this chart was in RPMs for a given diameter in different metals. I had one for drilling, (which I still have) one for milling (two and four flute) and one for turning. With my selective memory which only retains unusable information, I don't remember speeds and feeds. My charts were great I had filled in the metric diameters by hand and with a bit of trial and error, things worked well! Has anybody got or could point me to a set of charts that would cover my needs? I've heard that Starret published one, but I've been all over the web and I still haven't found what I need!
Regards, Matthew
