y = R sin(t) / (1 + cos(t)) where R is the radius of the outer arc segment, and t is the angle between the x-axis and the ray from the origin through the center of the large circle. For the second case where the large circle is tangent to the inner edge, the center point of the large circle is.
This page explains the machining methods for fillets and rounds of various products, rules for their notation in drawings, the relationship between these corners and strength, and how to measure rounded corners.
The proper way to make this measurement accurately is with a set of radius gauges. They are a set of know concave and convex radii essentially punched out of steel that you push up against your piece to check if the radius matches the tool.
If it's a simple 90 degree radius curve/fillet, those values should be the same and should be equal to the radius. You could also try finding the center point of longer circular curves to determine the radius.
A fillet is indicated on a drawing in the same way as a round, illustrated in Figure 2, with a dimension that includes the Radius symbol and radius length. Learn more about fillets and rounds in the video below:
To choose which one ($+$ or $-$) is the "correct" fillet, you'd need to know the starting and ending angles of the two circular arcs to be filleted. In practice, you just calculate both, and test which one is the correct one.
The formula for fillet radius is: r = (D^2 - d^2) / 8D, where D is the diameter of the shaft, d is the diameter of the hole, and r is the fillet radius. Related Questions. Q: What is the importance of fillet radius in machine design?
The fillet radius can be calculated using the formula: r = (D - d) / 2, where D is the major diameter of the shaft, d is the minor diameter of the shaft, and r is the fillet radius.
Calculation Example: A fillet is a curved section that connects two intersecting surfaces. In the case of a shaft, the fillet connects the shaft to a shoulder or hub. The fillet radius is the radius of the curved section.
It is common to find a fillet where two parts are welded together. In mechanical engineering, a fillet (pronounced / ˈfɪlɪt /, like "fill it") is a rounding of an interior or exterior corner of a part. An interior or exterior corner, with an angle or type of bevel, is called a "chamfer".
