Within the Areaclear cycle you can define a draft wall with optional blend radii from the cycle dialog. This frees you from having to generate blend radius geometry or other geometry for the wall. The draft wall parameters will be applied to the profile and any islands contained within the profile.
Draft Angle - Defines the draft angle from the vertical. The angle is always a positive number ranging from >0 to <90. The draft angle runs from the cycle level to the depth.
Upper Radius - Defines a blend radius between the profile level and the draft wall.
Lower Radius - This is a blend radius between the depth and the draft wall.
Digitise Contour Wall - Check to take the draft wall values from a digitised entity rather than entering the individual values.
Cut Increment - Specifies the maximum depth of each successive cut. This must be a positive value. If specified, one or more roughing passes are generated before the final finish pass. Note that the Cut Increment must be specified so that the tool intersects the geometry on the first pass. Otherwise the system cannot detect the geometry and displays an error message. (This allows the system to identify island profiles correctly.)
Cusp Height - Specifying this generates an effective cut increment at each level, which will not be exceeded. If specified, Cut Increment must also be specified. The Cut Increment is used instead of the Cusp Height if it is lower than the effective cut increment.
Stay at Depth - Check to stop the tool from retracting when the tool moves from one profile to the next, providing the distance moved by the tool is not more than the tool diameter. The alternative is for the tool to rapid to a safe position. This can vary depending on the Optimise Link Move and the Depth parameters selections.
Optimise Link Moves - Check to minimise any retract move between profiles wherever possible. If the box is unchecked, the tool will always move to the Clearance height between profiles. The cycle determines the retract height by finding the height at which the tool can move freely to the next position. The cycle then adds the Cut Increment and the Safe Distance to this retract height for added safety. If the cycle cannot find an optimal path to the next position, the tool will retract to the Clearance plane.
Cut by Region - Check to force the cycle to machine the profiles in regions. Regions are groups of profiles that represent a boss (hill) or pocket (valley). All regions will be completed before the cycle moves to the next region. Otherwise all profiles on a level are machined before moving on to the next level. When unchecked, all profiles on a level are machined before moving on the next level.
Island Facing
This option allows you to machine the stock material that has been left on top of the island(s) and any areas where the tool was too large to fit between islands and/or boundary.
Enable Island Facing - Check this to enable the Island Facing option.
Z Offset - Specifies the amount of material to be left on top of the island.
Note that islands will not be faced if the island height plus its Z offset is at or above the Z level setting.
