5X Aerospace Geometry

The selection of various geometric entities may be required to execute a 5X Aerospace procedure. The type of geometric entity to be selected, depends on the machining strategy selected in the Tool Trajectory dialog under the Finish tab.

5X Aerospace machining strategy	Geometry required

Parallel Cuts	None
Cuts Along Curve	Lead Curve
Morph between 2 Curves	Upper Curve; Lower Curve
Parallel to Curve	Single Edge
Project Curves	Projected Curves
Morph between 2 Surfaces	Upper Surface; Lower Surface
Parallel to Surface	Single Surface

The following specific geometry can be selected either from the Tool Trajectory dialog or from the Geometry branch:

Geometry Type	Data Required	No. of Entities	Geometric Similarity

Drive Faces	Nurbs + triangulation	one set	Similar to Part Surfaces
Check Faces	Dummy Nurbs + triangulation	0-4 sets	Similar to Check Surfaces
Boundary Curves	Nurbs	0-2 contours	Like today
Boundary Faces	Nurbs + triangulation	0-2 sets	Similar to Part Surfaces
Tilt lines	Nurbs	0-not limited	Similar to Part Surfaces, however, in the Selection Filter, only Lines are pickable. These lines must be predefined from the cutter tip to the spindle. Important: To ensure the correct tool orientation, the direction of the tilt lines is most important. The start point of the lines should be at the cutter tip and the end point should be towards the spindle.
Tilt Curve	Nurbs	0/1	Similar to a Top Contour in the Ruled Surface procedure

Note: In the 5X Aerospace procedure, some faces can be defined as both Drive and Check Surfaces.

The following specific geometry can only be selected from the Tool Trajectory dialog:

Object	Data Required	No. of Entities

Start Point	X, Y ,Z	0/1 point
Tool orientation guiding Point	X, Y, Z	0/1
Tilt from point	X, Y, Z	0/1
Tilt through point	X, Y, Z	0/1
Reference line for tilt angle	(X1, Y1, Z1) (X2, Y2, Z2)	0/1
Limit Points	(X1, Y1, Z1) (X2, Y2, Z2)	0/2 point
User defined direction	X, Y, Z	0/1
Cuts angle	angle pick	0/1
