      <hr noshade="true">
      <p class="para_topic">Cut Type enables you to define how the cutter moves from one cut pass to the next. The options are used in combination with either the Parallel Lines, Radial Lines, or Concentric Arcs cut patterns.</p>
      <p class="para_topic">When used in combination with the Parallel Lines pattern, Zig-Zag, Zig, and Zig With Contour work in the same way as their counterparts in Planar and Cavity Mill.</p>
      <div class="title_division">Zig-Zag</div>
      <p class="para_division">Zig-Zag creates passes that cut in opposite directions while stepping over in one direction. It works in combination with Parallel Lines, Radial Lines, and Concentric Arcs patterns. The system generates a Zig pass in one direction, steps over to the next pass while continuing to cut, and creates a Zag pass in the opposite direction.</p>
      <p class="para_division">This cut type maximizes cutting moves by allowing the tool to remain continually engaged during stepovers. The result of cutting in opposite directions is a series of alternate Climb and Conventional cuts.</p>

      <p class="para_division">For additional details, refer to the discussion of Zig-Zag in Planar and Cavity Milling.</p>
      <div class="title_division">Zig</div>
      <p class="para_division">Zig is a one-directional cut type that traverses from one cutting pass to the next by retracting, traversing to the start of the next pass, and cutting again in the same direction.</p>

      <p class="para_division">For additional details, refer to the discussion of Zig in Planar and Cavity Milling.</p>
      <div class="title_division">Zig with Contour</div>
      <p class="para_division">Zig with Contour is a one-directional Zig type cut that also follows the boundary contour along the stepovers.</p>

      <div class="title_division">Zig with Stepover</div>
      <p class="para_division">Zig with Stepover creates a Zig pattern with a cutting Stepover. The following figure illustrates the sequence of cutting and Non-Cutting moves for Zig with Stepover. Pass 1 is a cutting move. Passes 2, 3, and 4 are Non-Cutting moves. Pass 5 is a Stepover and a cutting move. Pass 6 repeats the sequence.</p>

      <div class="title_figure">Zig with Stepover with Parallel Lines Pattern</div>
      <div class="title_division">Pattern Center</div>
      <p class="para_division">Pattern Center allows you to interactively or automatically define the center point of Concentric Arcs and Radial Lines cut patterns. Specify enables you to interactively define the center point using the Point Subfunction. Automatic allows the system to determine the most efficient position for the pattern center based on the shape and size of the cut region.</p>
      <div class="title_division">Cut Angle</div>
      <p class="para_division">Cut Angle determines the angle of rotation for the Parallel Lines Cut Patterns only. The angle of rotation is measured with respect to the XC axis of the Work Coordinate System (WCS). When you choose this option, you may key in an angle by selecting User Defined, choose Automatic for the system to determine the cutting angle for each cutting region, or choose Longest Line for the system to establish the cut angle parallel to the longest line segment in the peripheral boundary. The Longest Line option is intended to be used only with boundaries containing distinguishable linear segments. If the peripheral boundary does not contain a line segment, the system searches for the longest line segment of the interior boundaries.</p>

                  <p class="para_note_body"> NOTE: After you exit the Cut Parameters dialog box, moving the WCS will not affect the cut direction and the cut angle will be recalculated next time the dialog is presented. Although you key in an angle relative to the Work Coordinate System, the Cut Angle is stored in the system relative to the Absolute Coordinate System. This allows the Cut Angle to be used in a Template for other Part files.</p>

      <div class="title_division">Display Cut Direction</div>
      <p class="para_division">This option is available if the Cut Angle is set to User Defined. A cut direction vector will be displayed.</p>
      <div class="title_division">Outward / Inward</div>
      <p class="para_division">Outward and Inward allow you to specify a pocketing method that determines whether to cut from the inside out or the outside in of a Follow Pocket, Concentric Arcs, or Radial Lines cut type.</p>

      <div class="title_division">Stepover</div>
      <p class="para_division">Stepover specifies the distances between successive cut passes. The Stepover options that are available are determined by the specified Cut Type (Zig, Zig-Zag, Radial, etc.) The numeric value or values required to define the stepover will vary depending on the stepover option selected. Constant, for example, requires that you enter a &quot;distance&quot; value in the subsequent line, while Variable displays an additional dialog box and requires several values.</p>
      <p class="para_division">The following Stepover options are available:</p>
      <div class="title_division">Constant</div>
      <p class="para_division">Constant allows you to specify a fixed stepover distance between successive cut passes. Stepover distance is measured between the cut passes of the Drive Path. When used with the Radial Lines cut type, the Constant distance is measured along the arc length at the boundary point farthest away from the center. This option is similar to the Constant option in Planar Milling.</p>
      <div class="title_division">Scallop</div>
      <p class="para_division">Scallop allows the system to determine the stepover distance based on the scallop height you enter. The Scalllop height evaluation is computed for the Drive Path. 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 option is similar to the Scallop option in Planar Milling.</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. The effective tool diameter is the diameter of the cutter that actually touches the floor of your pocket. For ball end mills, the system uses the full tool diameter as the effective tool diameter. This option is similar to the Tool Diameter option in Planar Milling.</p>
      <div class="title_division">Variable</div>
      <p class="para_division">Variable allows you to vary the stepover distance within a specified minimum and maximum value. The required input values differ depending on the selected Cut type. This option is similar to the Variable option in Planar Milling.</p>
      <div class="title_division">Angular</div>
      <p class="para_division">Angular allows you to define a constant stepover by keying in an angle. This option is used only in combination with the Radial Cut Pattern.</p>
      <div class="title_division">Additional Passes</div>
      <p class="para_division">Additional Passes enables you to specify an additional number of passes that allow the tool to step toward the boundary in successive concentric cuts for Profile and Standard cutting patterns. It uses the specified stepover to determine the distance between passes. It can be used to compensate for tool deflection by using a very small stepover in combination with a single additional pass, or it can create a cut pattern similar to Follow Pocket by using a large stepover in combination with several additional passes as illustrated below.</p>
