Hi,
Does anyone have a formula for calculating, or a chart for referencing Chip Load / Feed per Tooth when cutting mild steel? Ideally for a range of end mill HSS cutter diameters.
I am trying to calculate my estimated feed rate (IPM) using RPM x Chip load x # of flutes. But I have no chip loading charts or formula to work from, and I have no idea who manufactured my collection of HSS end mills (so cannot go to them).
Another question, how do I incorporate different cutting depths into the feed rate formula? Obviously, with increased depth I have to reduce feed rate?
I except these formulas produce only rough guide values, and many other factors such as HP, rigidity, tool sharpness and cutting conditions come into play. As long as I have rough figures to work from I can then adjust accordingly.
Please forgive my in-experience with this!
Thanks,
Jim
