Mill Type - The cutter can move along a profile on the left or right hand side. This, combined with the spindle direction, gives the type of cutting to be either Climb or Conventional.

Climb - Tool cuts on the left of the profile (i.e. material is on the right).

Conventional - Tool cuts on right of the profile

Optimised - Cycle is optimised to reduce link moves. The tool may cut on the left or right side.

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

Cusp Height - Specifies the height of the uncut material between each pass.

Previous Tool Diameter - When checked, the previously selected tool diameter will define the rest finishing areas.

Overlap - Specifies the distance the tool will overlap around the rest finishing areas.

Offset - Specifies the toolpath offset from the surface. Note that this is a three dimensional offset from the surface. The offset can be positive, but if negative, the offset must be smaller than the tool corner radius.

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.

Pencil Trace - Allows you to machine a final pass along the centre line of the machined area. The Pencil Trace will only be applied to regions that would normally be found by the Pencil Mill cycle and can be used to help clean up any cusps.

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

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.
