Depending on size of masonry above the beam the depths of cut shall be equal to the thickness of the beam, or equal the embedment depth of the beam into masonry. Rule of thumb - 2"

45 degrees
To properly install crown molding, you should cut the angles at 45 degrees.
the fire angle is the angle at which the thyristor starts working...
When cutting crown molding, two angles are typically used: the miter angle and the bevel angle. The miter angle is the angle at which the molding is cut horizontally, while the bevel angle is the angle at which the molding is cut vertically. These angles will vary depending on the type of crown molding and the corners being joined. It is important to measure and cut accurately to ensure a proper fit.

cut it to the correct length, creating an angle
To cut an 8-sided octagon, you should set your table saw to a 22.5-degree angle. This is because each internal angle of an octagon is 135 degrees, and the angle for the saw blade should be half of the exterior angle, which is 45 degrees. Therefore, cutting each side requires a 22.5-degree bevel.
Cut a 45 degree angle "going the other way".
When you say "crown cut" I think you are referring to a compound angle cut. A compound angle is 2 angles cut at the same time. In crown for instance you put the trim in the saw at a 45 degree angle, and tilt your saw blade at a 45 degree angle as well.
So that there is a bigger surface area exposed.
