      <p class="para_topic">The Minimum Clearance parameters have two purposes:</p>
      <ul>
         <li>
            <p class="para_item">Whenever the tool has to traverse to a new cut region or a new profiling pass, the software ensures that the traversal motions generated do not collide with the current in-process workpiece. For such traversals, you can define the minimum distance between tool path and in-process workpiece in the Minimum Clearance parameters. The system distinguishes between faces and diameters in these traversal movements. The system also applies collision avoidance to those traversal motions required for stepover from one rough cut to the next.</p>
         </li>
         <li>
            <p class="para_item">When retracting from a rough cut, the system uses the values entered in the Minimum Clearance fields following these rules:&nbsp;</p>
            <ul>
               <li>
                  <p class="para_item">If the level angle of the cut is aligned with a diameter, as in  <img align="bottom" src="graphics/num_1.gif" border="0"> below, &nbsp;the system retracts from the rough cut by the amount you set in the From Diameters field.
