I am cutting 3/4" OSB sheets using an Amana 46178 3/8" 2 flute Solid Carbide Compression bit. I am cutting at 21,000 RPM and 5 in/s or 300 IPM. This is industrial production so cutting faster would be helpful.
Found Amana (http://www.toolstoday.com/p-6265-sol...keywords=46371 ) has a 3 flute bit that according to the graphic can do a 1xD pass at close to 800 IPM or 13 in/s @ 24,000 RPM.
Using Shopbot's chip load calculator I get this bit is capable of doing a chip load of 0.011 in/flute. Using same calculator solving for speed at my router's speed (21,000RPM) I should be able to run this bit at 11.6 in/s or 696 IPM.
In other words, using the Amana 46371 bit I can do the same cut at twice+ the speed of the Amana 46178 bit.
Is this correct? I am not experienced in doing these calculations.
