      <p class="para_topic">Internal Trim allows you to make an internal profile cut or series of cuts on the inside of the boundary. If you select an Internal Trim Sequence you get three separate operations. If you select an Internal Trim operation you will have all three operations in a single operation.</p>
      <p class="para_topic">Rough Passes are the tool paths that cut the bulk of the material to be removed. This leaves a tab that keeps that material from falling.</p>
      <p class="para_topic">Backburn cuts through the tab to let the material to be removed fall.</p>
      <p class="para_topic">Trim is the main profiling pass or passes.</p>
      <p class="para_topic">The figure below illustrates the function of these operations.</p>
