      <p class="para_topic">Convex Corner is available in Planar Mill for all profiling passes including Wall Cleanup and Finish Passes when using Zig or Zig-Zag. For the pocketing cut types (Profile, Follow Part, and Follow Periphery), Fillets and/or Slowdowns applies only to the profile passes.</p>
      <p class="para_topic">Convex Corner toggles between ADD ARCS and EXTEND TANGENTS.</p>
      <p class="para_topic">If you choose ADD ARCS, the system maintains tool contact with the material stock by inserting an arc equal to the radius of the tool into the tool path. The corner becomes the center of the arc.</p>
      <p class="para_topic">If you choose EXTEND TANGENTS, the system forms the corner by extending the tangents at the corners, thereby causing the tool to leave the boundary at corners during the pocketing operation. EXTEND TANGENTS only applies to the passes along the wall as illustrated below.</p>

      <p class="para_topic">EXTEND TANGENTS does not apply to passes that are away from the wall. For passes that are away from the wall, the system applies ADD ARCS is as illustrated below.</p>
