Contour Manager (NC): Contour Creation - Chamfer Detect

Select the By Criteria option in the Contour Manager. Then select the dropdown option Chamfer Detect from the Sets - Create and Edit dialog.
Select the Chamfer Detect option in the Contour Manager.

These parameters can either be set from the By Criteria dialog or from the parameters displayed from the Chamfer Detect option.

Contour Manager > By Criteria:	Contour Manager > Multi Contours Selection:
Criteria dialog for selecting contours with Boundaries = Chamfer Detect:	Auto Chamfer Detect, minimum parameters displayed:	Auto Chamfer Detect, all parameters displayed:

Parameters:

Climb

Select the cutting mode toggle option Climb / Conventional:

Climb
Conventional

Notes: The Climb/Conventional parameter sets the parameter of each created contour as follows:

In Chamfer Open Contour:
- If Climb, the Milling Direction = Left, Direction = Chaining Order.
- If Conventional, the Milling Direction = Right, Direction = Opposite to Chaining Order.
In Chamfer Closed Contour:
- If Climb, the Direction = Chaining Order, if Conventional the Milling Direction = Opposite to Chaining Order.
- If the contour is CW, the Milling Side = Outside. If CCW, the Milling Side = Inside.

Search for Imaginary Chamfers

Set the chamfer search mode from the dropdown list. This parameter obtains its initial value from the Contour Represents parameter in the Tool Trajectory branch of the parameter table for the Chamfer Open Contour and Chamfer Closed Contour procedures. However, the value in the graphics window can be changed via the dropdown list.

For additional information see the Contour Represents parameter.

Example:Example:

Faces Grouping Max. Gap

Contours Creation Max. Gap

Min. Contour Length

Contours smaller than the defined length will not be created.
Default = 0.

Min./Max. Circles Diameter

The diameter range values beyond which holes are not taken into account when creating contours.
Default Min. = Maximum Hole Diameter in the Preferences (NC > Drill > Tolerances).
Default Max. = 9999.

Min./Max. Ceiling Angle

The angle range values beyond which ceilings are not taken into account when the system searches for geometry from which to create contours.

If Min./Max. Ceiling Angle = 90°, then the system only detects ceilings that are parallel to the XY plane.
Example:Example:

Result when searching for Chamfer Geometry Top, Min./Max. Ceiling Angle = 90°:

The chamfer of the upper step is not detected, as the ceiling of the upper step is not parallel to the XY plane. The Min./Max. Ceiling Angle = 90° means that the system only detects ceilings that are parallel to the XY plane.

If Min. = 60° and Max. Ceiling Angle = 120°, then the system detects ceilings within that angle range from the parallel to the XY plane.
Example:Example:

Result when searching for Chamfer Geometry Top, Min. = 60°, Max. Ceiling Angle = 120°:

The chamfer of the upper step (with a ceiling of 95°) is detected together with the other ceilings that are parallel to the XY plane, as all the ceilings are within the defined range.

See Angle Limits, below.

Min./Max. Wall Angle

The angle range values beyond which walls are not taken into account when the system searches for geometry from which to create contours.

If Min./Max. Wall Angle = 0°, then the system only detects walls that are normal to the XY plane.
Example:Example:

Result when searching for Chamfer Geometry Top, Min./Max. Wall Angle = 0°:

The chamfer of the middle step is not detected, as the middle step is not normal to the XY plane. The Min./Max. Wall Angle = 0° means that the system only detects walls that are normal to the XY plane.

If Min. = 0° and Max. Wall Angle = 20°, then the system detects tapered walls up to 20° from the normal to the XY plane.
Example:Example:

Result when searching for Chamfer Geometry Top, Min. = 0°, Max. Wall Angle = 20°:

The chamfer of the middle step of 15° is detected together with the other walls that are normal to the XY plane, as all the walls are within the defined range.

See Angle Limits, below.

Min./Max. Chamfer Angle

The angle range values beyond which chamfers are not taken into account when the system searches for geometry from which to create contours.

If Min. = 44 and Max. Chamfer Angle = 46, then the system detects designed chamfers within the range of 44° to 46°.

See Angle Limits, below.

Angle Limits

The angle limits parameters and values that are displayed, depend on the Search for... parameter value.

Imaginary Chamfer:

Parameter	Default	Min.	Max.
Min. Ceiling Angle	60	45	120
Max. Ceiling Angle	120	60	150
Min. Wall Angle	-5	-45	45
Max. Wall Angle	30	0	60

Geometry Top:

Parameter	Default	Min.	Max.
Min. Ceiling Angle	60	45	120
Max. Ceiling Angle	120	60	150
Min. Chamfer Angle	Draft-1	10	84
Max. Chamfer Angle	Draft+1	11	85

Geometry Bottom:

Parameter	Default	Min.	Max.
Min. Chamfer Angle	Draft-1	10	84
Max. Chamfer Angle	Draft+1	11	85
Min. Wall Angle	-5	-45	45
Max. Wall Angle	45	0	60

In all cases, Min. Angle ≤ Max. Angle.

Draft is the conic angle of the cutter (for Conic cutters or Counter Sink cutters) or 45° otherwise.

There are three possible types of faces that can meet on a chamfer: Ceiling, Draft and Wall. The selected Search for parameter defines which two face types out of the three are used.

Approval Buttons

When OK or Apply are clicked, the system creates 2D NC contours, parallel to the procedure’s XY plane; duplicated contours are not created. Edges that are not parallel to the XY main plane of the procedure's UCS are disregarded.
