G97: spindle rotation- constant number of revolution "S". RPM = (1.000 x Cs) /( D x Pi) Unit ( Rev/ min)

X- coordinate ( the horizontal axis) = the diameter value. Y- coordinate ( the vertical axix) = the vertical axis = the cutting speed value. - G96: Setting of constant cutting speed - G97: a different function belonging to the same group needs to be used. - Example: G96 S120 (S is value of cutting speed 120)

LIMS = limitation of the maxium number of revolutions (LIMS = 4000) - D = (1000 x Cs) / (Pi x Nmax) Pages #95 SPO = programming of the angular orientation
