Description

The Mill Face tool creates a path to perform a facing operation on a horizontal surface. This operation is generally used:

to smooth out a rough stock surface,
to mill selected face(s) to desired depth in preparation for performing subsequent clearing operations within the boundary of the regions affected by this operation,
or to apply a finishing surface to the selected face(s).

This operation contains a DateBoundaryShape property that allows for a modified selection area based upon the selected face(s).

Select one or more faces to be surfaced. Note: If selected faces exist at different heights, then all will be milled to the Final Depth setting.
There are several ways to invoke the command:
- Press the CAM MillFace button.
- Select the CAM → Face option from the menu.
Select the correct DateBoundaryShape setting to modify the milling area based on the face(s) selected as Base Geometry.
Adjust the other properties as needed. They are listed further below.

Using it on an inclined plane may produce unexpected results: it will still produce a path to cut a horizontal surface. The extent of the cut will be the vertical projection of the inclined plane, performed at a height corresponding to the lowest point in that plane.

Since the CAM tools work on the geometry of the selected edges/faces only, and do not relate to the rest of the 3D model, the paths will not go beyond the bounds of the chosen plane, even if it is surrounded by unused stock or air. This will leave unmachined corners. These can sometimes removed with one of the dress-up tools to be found on the CAM menu.

This tool will not work on a vertical plane or vertical non planar surface. Vertical operations can be achieved by using the face profile tool or edge profile tool. These will need the selection of a face or closed loop of edges including the top or bottom edge of the vertical surface desired). The extent of the path can then be reduced using the Boundary Dress-up tool to be found on the CAM menu. With the Dress-up tool, select Create Box option and reduce the size to limit the scope of the profile path. These settings will not allow the origin of the boundary box to be moved, however. This must be done by adjusting the Placement settings in the tree view.
This will work on compound surfaces such as several vertical planes or cylindrical surfaces joined together, so long as they form one continuous surface.

Note : The names of some Properties in this list differ a little from the same settings used in the Task Window Editor.

Base

Note: It is suggested that you do not edit the Placement property of path operations. Rather, move or rotate the CAM Job model as needed.

Depth

Face

DateBoundaryShape: Shape to use for calculating Boundary
DateClearEdges: Clear edges of surface (Only applicable to BoundBox)
DateExcludeRaisedAreas: Exclude milling raised areas inside the face.
DateOffset Pattern: Clearing pattern to use. (Select in which manner the horizontal movements should be done.)

Path

Pocket

DateCut Mode: The direction that the toolpath should go around the part ClockWise (CW) or CounterClockWise (CCW)
DateExtra Offset: Extra offset to apply to the operation. Direction is operation dependent.
DateStartAt: Start pocketing at center or boundary
DateStep Over: Percent of cutter diameter to step over on each pass
DateZig Zag Angle: Angle of the zigzag pattern
DateOffset Pattern: Clearing pattern to use
DateMin Travel: Use 3D Sorting of Path
DateKeep Tool Down: Attempts to avoid unnecessary retractions.

Rotation

DateAttempt Inverse Angle: Automatically attempt Inverse Angle if initial rotation is incorrect.
DateEnable Rotation: Enable rotation to gain access to pockets or areas not normal to Z axis.
DateInverse Angle: Inverse the angle of the rotation. Example: change a rotation from -22.5 to 22.5 degrees.
DateLimit Depth To Face: Enforce the Z-depth of the selected face as the lowest value for final depth. Higher user values for final depth will be observed.
DateReverse Direction: Reverse orientation of Operation by 180 degrees.

Start Point

DateStart Point: The custom start point for the path of this operation.
- DateX: X distance value
- DateY: Y distance value
- DateZ: Z distance value
DateUse Start Point: Make True, if manually specifying a Start Point. Set the start point in the property data Start Point field.
