      <p class="para_topic"><b class="uiTerm">Part Floor Stock</b> and <b class="uiTerm">Part Side Stock</b> replace <b class="uiTerm">Part Stock</b> for Cavity Milling.
      </p>
      <p class="para_topic"><b class="uiTerm">Part Floor Stock</b> specifies the material remaining on the floor and is measured vertically along the tool axis. <b class="uiTerm">Part Floor Stock</b> applies only to part surfaces that define cut levels, are planar, and are normal to the tool axis (surface normal vectors are parallel to the tool axis).
      </p>
      <p class="para_topic"><b class="uiTerm">Part Side Stock</b> specifies the material remaining on the walls and is measured normal to the tool axis (horizontally) at each cut level. It applies to all part surfaces (planar, nonplanar, vertical, angled) from which a horizontal measurement can be taken.

      <p class="para_topic">For <b class="uiTerm">Part Floor Stock</b>, surface normal vectors must point in the same direction as the tool axis vector. This prevents applying <b class="uiTerm">Part Floor Stock</b> to undercut surfaces as illustrated below.

      <div class="title_figure">Surface Normal Vectors</div>
      <p class="para_topic">Because the actual side stock may be unpredictable on angled and contoured surfaces, <b class="uiTerm">Part Side Stock</b> is primarily intended for use on parts with predominately vertical walls.
