Strategy - Select the combination of cycles to be used:

Parallel Lace/Z Level - Flat or shallow regions are detected and machined using Parallel Lace. The remaining regions are machined using Z Level Finishing.

Z Level/Parallel Lace - Alternatively, machine all steep regions first with Z Level Finishing, followed by Parallel Lace for the flatter regions.

Perpendicular Lace - Use two Parallel Lace cycles to machine the part. The first cycle machines the flatter areas, while the second cycle machines the steeper regions, cutting at right angles to the first cycle.

Boundary Collapse/Z Level - Flat or shallow regions are detected and machined using Boundary Collapse. The remaining regions are machined using Z Level Finishing.

Z Level/Boundary Collapse - Alternatively, machine all steep regions first with Z Level Finishing, followed by Boundary Collapse for the flatter regions.

Mill Type - Choose either Climb, Conventional or Optimised.

Offset - Specifies an offset normal to the surface. Any negative offset may not be greater than the tool's corner radius, as this would generate an incorrect toolpath.

Using a Negative Offset
A negative offset cannot be equal or greater than the tool radius. When machining with a negative offset this produces the same results as reducing the tool radius by the offset, e.g. a 4mm ballnose tool used on a cycle with a -1.5 offset means the part is calculated using a 1mm ballnose tool. If the resultant tool size is very small please be aware that the tool could fall between small gaps in the model and the calculation time increases.

Tolerance - Specifies the maximum deviation of the generated toolpath from the selected surface.

Flat/Steep Angle - Changes the angular plane that separates the two cycles defined by the Strategy. The default angle is 45 degrees.

Feature Name - Enter a name here to allow labelling of digitised information for this cycle to enable "pickup" of this information in another (similar) cycle.

% Stepover - Specifies the tool stepover distance between each pass as a percentage of the tool diameter.

Cut Increment - Specifies the depth of each successive cut. This must be a positive value. The cut increment value sets the vertical distance between successive waterline planes.

Maximum Cusp Height - The Maximum Cusp Height value, Flat/Steep Angle and the tool geometry are used to calculate the %Stepover and Cut Increment automatically.

Bottom to Top - Check to cut the lowest level first and work upwards.

Angle - Specifies the angle between each pass and the X axis of the Initial CPL.

Unbounded Primary Cycle - (Perpendicular Lace strategy only) Check this option to allow the primary toolpath to machine the entire model first. The secondary toolpath then machines the steeper regions.

Clearance - Specifies the absolute height at which the tool can move freely in the XY plane without encountering any material or fixtures. If more than one profile is machined with a single cycle, or the tool cannot enter an area, the tool lifts to the Clearance plane between each profile.

Level - Specifies the absolute height at which the cycle is to start.

Depth - (Z Level Finishing only) Specifies the depth (incremental from the Level) to complete the machining. Alternatively, input a calculation for the depth.

Feedrate - Specifies the rate of movement in the workplane.

Plunge Feed - Specifies the rate of movement in the direction of the tool axis.

Speed - Specifies the tool spindle speed.
