This option controls whether true radial feedrate calculations are used for circular interpolation. During circular interpolation, the velocity of the cutting edge of the tool is not the same as the velocity of the center of the tool radius. For example, a .20 tool radius driven around a .005 corner at 10 IPM would actually result in a tangential velocity of much less than 10 IPM. This option directs the postprocessor to adjust programmed feedrates to correct this condition. CAUTION:The caveat here is that adjustment of tangential feedrate can cause extremely high feedrate calculations under conditions where the cutter is large and the toolpath addresses small outside radii.
