      <p class="para_topic">This dialog allows you to define how the system controls feedrates for lathes. You can specify the feedrate mode G-code that determines the mode (IPM, IPR) that your lathe outputs. For the feedrate mode G-codes to output, the word must be included in every motion block.&nbsp;The default lathe postprocessors include this as basic functionality.&nbsp; You can also define the format and the&nbsp;maximum and minimum feedrate value that is valid within each mode.&nbsp; See the  <a class="links" href="javascript:void(0)" onclick="top.openFile('postbuilder/ncdata_format.html');return(false);">format</a> section for details on how to specify and edit formats.&nbsp; The postprocessor will also give a warning if the IPR value and the current spindle RPM value exceed the maximum IPM value or is less than minimum IPR value.
      </p>
      <p class="para_topic">By default your postprocessor outputs IPR mode when you specify an IPR feedrate for a specific motion and outputs IPM mode when you specify an IPM feedrate for a specific motion.&nbsp;The UDE that controls this function is the&nbsp;SET/MODE command.&nbsp;SET/MODE,OFF is the default mode and means that the feedrate output mode is the same as the feedrate mode for that motion. SET/MODE,IPM means that all feedrate output is output in IPM mode regardless of the input feedrate mode.&nbsp;Likewise SET/MODE,IPR means that all feedrate output is output in IPR mode regardless of the input feedrate mode.&nbsp;You can also get inverse time feedrates (FRN) output by specifying the UDE SET/MODE, FRN.</p>
