Surface Speed Unit. \par Metric - Millimetre. Metres per Minute, M/Min. \par Imperial - Inches. Feet per Minute, Feet/Min. \par \par A G96 command for surface speed control is written in the following format: \par G96 S __ ; \par where, \par S __ is the surface speed (M/Min or Feet/Min)\cf1\b\fs24 \par \par \par \par \par \par }
