      <p class="para_topic">The No Core option allows you to burn out the internal material of a part without generating slugs. Slugs are loose pieces of metal that may be created during the wire EDM process. When slugs are created they often get stuck inside the machine tool causing damage to the machine tool. Slugs may also cause the wire to move out of alignment and cause the part to be machined out of tolerance. In No Core, instead of cutting around the outside of the shape and leaving a slug, the tool path removes all of the material within the target region. It starts from the user defined start point (thread point) and removes the material in a spiral cut pattern within the region. If the target cut region contains existing holes or voids, time will not be wasted by feeding through those open areas.</p>

      <p class="para_topic">No Core begins cutting at the user defined thread point where a hole has been drilled. To avoid cutting through areas that have already been machined, the tool path cuts in spirals until it reaches a boundary or a void. Then it begins cutting in zigzag, concentric arcs without cutting the boundaries or the voids, or crossing over itself. This saves time by eliminating cut paths through areas that have already been cut.</p>
      <p class="para_topic">If inner boundaries or a thread point have not been specified, the tool path cuts the selected WireEDM geometry in follow part pattern. </p>
