ours in the YZ plane
Chamfer/rounding arc in YZ plane
Select the form elements.
Select a chamfer.
Select rounding arc.
Enter the chamfer width BR or the rounding radius BR.
Chamfer/rounding arc as first element: Enter element position AN.
Chamfers/rounding arcs are defined on contour corners. A "contour
corner" is the point of intersection between the approaching and
departing contour elements. A chamfer or rounding cannot be
calculated until the departing contour element is known.
ICP integrates the chamfer/rounding arc in smart.Turn on the basic
element G181, G182 or G183.
Contour begins with a chamfer or a rounding arc:
Enter the
position of the intended corner as starting point. Then, in the form
element menu, select chamfer or rounding arc. Since the introducing
contour element is missing, you enter the element position AN to
clearly define the position of the chamfer or rounding arc.
ICP converts a chamfer or rounding arc at the start of the contour to a
linear or circular element.
