WebJun 19, 2003 · (I read that the larger diameters relate to a larger chip load and lower spindle RPM - to understate this, that is not very specific!) Also, according to the tables I'm looking at for plywood, the chip load can be anywhere from .015-.030" with the RPM anywhere from 9,000-16,000. This puts the feed rate anywhere from 562 IPM to 1440 IPM. WebDepth of Cut: 1 x D Use recommended chip load 2 x D Reduce chip load by 25% 3 x D Reduce chip load by 50% Simple Machining Calculations: To find RPM: (SFM x 3.82) / diameter of tool To find SFM: 0.262 x diameter of tool x RPM To find Feed Rate: RPM x # of flutes x chip load To find Chip Load: IPM / (RPM x # of Flutes) WebThe combination of three factors will affect the life of the cutting tools before renewal of the edge (either by replacing an insert knife, or having a fixed tool resharpened).
