      <p class="para_topic">The Radial Cut Drive Method enables you to generate Drive Paths perpendicular to and along a given boundary, using a specified Stepover distance, Bandwidth and Cut Type. This drive method is useful in creating cleanup operations.</p>

      <p class="para_division">Edit displays the Edit Radial Boundary dialog box which enables you to modify individual boundary members and add or subtract Boundaries from the existing set.</p>
      <p class="para_division">Select displays the Radial Boundary or Temporary Boundary dialog box allowing you to define the area to be cut. The Radial Boundary dialog allows you to select permanent boundaries for the operation and is only displayed if permanent boundaries currently exist in your part. If multiple Boundaries are defined, a lift is applied, allowing the tool to traverse from boundary to the next. Once a Boundary has been defined, Select toggles to Reselect which allows you to completely redefine the boundary. For general information on permanent and temporary boundaries, refer to the Boundaries discussion. For information on how to create temporary boundaries within an operation, refer to Temporary Boundaries.</p>
      <p class="para_division">Display highlights the current boundaries.</p>
      <div class="title_division">Bandwidth</div>
      <p class="para_division">Bandwidth defines the total width of the machined area measured in the plane of the boundary. The bandwidth is the sum of the Material Side and Opposite Side offset values.</p>
      <p class="para_division">The Material Side is the right-hand side of the boundary as you look in the direction of the boundary indicators as illustrated below. The Opposite Side is the left-hand side. The sum of the Material Side and Opposite Side cannot equal zero.</p>

      <div class="title_division">Cut Type</div>
      <p class="para_division">Cut Type enables you to define how the cutter moves from one cut pass to the next. The following options are available.</p>
      <ul>
         <li>
            <p class="para_item">Zig-Zag</p>

      <div class="title_figure">Zig-Zag and Zig for Radial Cut Drive Method</div>
      <div class="title_division">Stepover</div>
      <p class="para_division">Stepover allows you to specify the distances between successive Drive Paths. The stepover is a straight line distance measured either at the widest point between successive drive paths (A-B) or at the boundary intersection (C-D), depending on the Stepover method used.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/stepover.gif"></p>
      </div>
      <div class="title_figure">Stepover</div>
      <p class="para_division">Each of the following Stepover methods require you to enter a corresponding Distance value.</p>
      <div class="title_division">Constant</div>
      <p class="para_division">Constant allows you to specify a fixed linear distance between successive Cut Passes. This distance is measured at the boundary (between points C and D illustrated above).</p>
      <div class="title_division">Scallop</div>
      <p class="para_division">Scallop allows the system calculate the Stepover that limits the scallop height to the value that you enter. The system limits the size of the stepover to roughly less than two-thirds of the tool diameter regardless of what you specify as the scallop size. This value is applied at the widest point of the cut pass (between points A and B illustrated above).</p>
      <div class="title_division">Tool Diameter</div>
      <p class="para_division">Tool Diameter allows you to define the Stepover in terms of a percentage the effective tool diameter. This distance is measured at the boundary (between points C and D illustrated above).</p>
      <div class="title_division">Maximum</div>
      <p class="para_division">Maximum requires you to key in a value defining the Maximum allowable distance between Stepovers. This value is applied at the widest point of the cut pass (between points A and B illustrated above).</p>
      <div class="title_division">Follow Boundary / Reverse Boundary</div>
      <p class="para_division">Follow Boundary and Reverse Boundary allow you to determine the direction the tool travels along the boundary. One or the other may be activated. Follow Boundary causes the tool to Zig or Zig-Zag down the boundary in the direction of the boundary indicators. Reverse Boundary causes the tool to Zig or Zig-Zag down the boundary in the opposite direction of the boundary indicators.</p>

      <div class="title_figure">Follow and Reverse Boundary</div>
      <div class="title_division">Climb Cut / Conventional Cut</div>
      <p class="para_division">Climb Cut and Conventional Cut allow you to define the direction the Drive Path will cut in relationship to the spindle rotation. These options are only available for the Zig Method.</p>

      <div class="title_figure">Climb Cut and Conventional Cut used with Follow Boundary</div>
      <div class="title_division">Projection Vector</div>
      <p class="para_division">Projection Vector is an option common to most Drive Methods. It enables you to determine how the Drive Points project to the Part Surface.</p>
      <div class="title_division">Display Drive Path</div>
      <p class="para_division">Display Drive Path displays the current Drive Path used to create the Tool Path. The path is created as a temporary element and is for visual reference only.</p>
