Pattern

Use the Pattern page to specify the limits and orientation of the toolpath. The options on this page are dependent on the selected strategy:

Limits

Azimuth angle — Each toolpath starts at the Start angle and ends at the End angle. The Angular limits are measured counter-clockwise about the Z axis, with 0 at the X axis. This option is available only if you select a Style of Circular, Linear, or Radial.

Elevation angle — Defines the start angle, end angle and the angle between consecutive passes. The elevation values are measured from the horizontal plane.

Parametric pattern limits — Select to limit the machining area using the Start and End fields. This option is only available for Curve projection finishing. The example below shows a Start of 0 and an End of 0.5:

Height — Specify the height each toolpath starts and ends at. The toolpath succesively adds stepover until the end height is reached.

Width — Specify the width each toolpath starts and ends at. The toolpath succesively adds stepover until the end width is reached.

Limits (Distance) — Enter the limits of the pattern. Each pass goes from Start to End. The first pass is at Start, successively adding Stepover until End is reached.

Pattern

Style — Select a style to specify the shape of the pattern projection.

  • Linear — Produces a line pattern.
  • Circular — Produces a circular pattern at sequential Z heights, in a similar way to constant z finishing.
  • Spiral — Produces a spiral pattern.
  • Radial — Produces a pattern of lines extending radially outwards from a point.

Pattern direction — Select the orientation of the pattern. The two options available are U and V (the surface parametric directions).

  • Pattern direction of U:

  • Pattern direction of V:

Spiral — Produces a spiral path. This minimises the number of lifts of the tool and maximises cutting time while maintaining more constant load conditions and deflections on the tool.

Ordering — Select how successive toolpath segment are machined. For more information, see Raster ordering. This option is available only if you select a Style of Circular or Linear.

  • One way — The tool cuts only in one direction.
  • Two way — The tool can cut in both directions.
  • Two way joined — The tool cuts in both directions and joins successive toolpath segments.

Start corner — Select the corner where machining starts. You can choose between four different start corners.

Min U min V

Max U min V

Min U max V

Max U max V

Sequence — Select the sequence of toolpath segments. This can be useful during line projection of shapes such as bottle molds. This option is available only if you select a Style of Circular or Linear.

  • None — Maintains the raster-type movement.
  • Out to in — Sequences the toolpath segments to machine inwards from the pattern's outer region.

  • In to out — Sequences the toolpath segments to machine outwards from the pattern's inner region.

Direction — Specifies the rotational direction of a spiral pattern. This option is only available if you select a Style of Spiral.
