      <p class="para_topic">Reversal Mode determines in which sequence the reversals of a cut region (i.e. the valleys of the part boundary found in this cut region) are visited for material removal. You may select the following options:</p>
      <ul>
         <li>
            <p class="para_item"> As Level</p>
         </li>
         <li>
            <p class="para_item"> Inverse</p>
         </li>
         <li>
            <p class="para_item"> Closest</p>
         </li>
         <li>
            <p class="para_item"> Cut Later</p>
         </li>
         <li>
            <p class="para_item"> Omit</p>
         </li>
      </ul>
      <div class="title_division">As Level</div>
      <p class="para_division">If you choose this Reversal Mode, the system will perform each rough cut at maximum reach into the reversal. As soon as a cut level is reached which leads into lower reversals, the system will continue to cut the reversal which comes next as seen in the direction of the level angle.</p>

      </div>
      <div class="title_figure">As Level Reversal Mode</div>
      <div class="title_division">Inverse</div>
      <p class="para_division">With an Inverse Reversal Mode, the reversals are cut in a pattern opposite to the As Level Mode. In other words, the system will cut the last reversal first and work backwards to the first reversal.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/turn_Rough_fr26_b.gif"></p>
      </div>
      <div class="title_figure">Inverse Reversal Mode</div>
      <div class="title_division">Closest</div>
      <p class="para_division">The Closest option is especially useful in combination with the zig-zag cut strategy, as the system will always choose to next cut that reversal which is closest to the current tool position. With a particularly complicated part boundary, this can save considerable machining time as tool travel is reduced.</p>
      <div class="title_division">Cut Later</div>
      <p class="para_division">Here the rough cuts leading into lower reversals are only carried out at full depth of cut for the first reversal which is met. The other neck-down areas are initially fully omitted from cutting and get machined only after the earlier ones are cut. This principle is applied recursively to all reversals met later which belong to the same cut region.</p>

      </div>
      <div class="title_figure">Cut Later Reversal Mode</div>
      <div class="title_division">Omit</div>
      <p class="para_division">The final option Omit does not cut any neck-down areas met after the first reversal.</p>
