When trying to "fillet" intersecting lines, the radius seems to be about 1/2". Diamond conical indenters with an apex angle of 120° and the corner radius at the apex equal to 0.2 mm are used to determine the hardness of pieces made from low-tempered hardened steel or hard alloys (GOST 9013–59). The Fillet command is useful for joint two lines, arcs, splines, or polylines by 0 angle radius (sharp corner) or by any curve or by the soft curve.This command is the time-saving command. A variable radius corner means that at least two different constant radii are applied to two entire edges. After performing the scenario, also see Variable Radius Fillets Using a Spine. To change the fillet radius: Click Fillet Options panelFillet Size drop-down. ); 1 /16 in. If the fillet is smaller than the edge on the left (0.8 mm) the fillet will come out as supposed but with anything over that it fails. Find Select the desired fillet size from the drop-down. You need to specify the corner radius to determine the size of a filleted or scalloped corner. Active 6 years, 9 months ago. For a part with an inner corner radius half the nominal wall thickness, a stress concentration factor of 1.5 is a reasonable assumption (see Figure 2). Dennis Bacon Dec 28, 2017 8:31 PM. The final piece of the puzzle is keeping the outside of the hole, equidistant to the outside edge of the roundover. First, a terminology review: in design and machining, a chamfer is a sloped or angled corner or edge, and a fillet is a rounded corner or edge. on sman lorgings (3 to 12 in. 1. You could wire the fillet radius to the scale params on the Xform. corner radius is related to material removal to avoid sharp corners whereas fillet radius is material addition to strengthen the fabricated or machined structure.

The variable radius fillet (108, 110) may be disposed within the pocket (82) and extend between the forward buttress (69) and the aft buttress ... Sharp corners should be avoided; for aluminium and magnesium the minimum radius should be 0.4 mm (1/64 in) and for steel corners should be 0.75 mm (0.030 in) and fillets should be 3 mm (0.12 in). On the other hand, how many drawings show radiused corners when chamfers would do as well? A new separate Fillet entry (followed by a sequential number if there are already existing fillets in the document) is created in the Project tree. Open the VariableRadiusFillet1.CATPart document. You add a fillet or round to a polyline by setting the current fillet radius to a nonzero value and selecting two line segments that intersect. If the part has a load bearing function, then the upper end is recommended. The radius is measured from the curve’s center to its perimeter. The top row shows the proposed fillets on the left and the filleted results on the right. 10% of the nominal wall, this factor will increase to 3. As with radii, a uniform wall thickness is preferred, so a chamfer on an outer edge should be copied on the inner corner. From left to right, you can see the radius of a filleted corner and the radius of a scalloped corner. If you want to order a worktop featuring radius corners, we recommend the use of our Online Bespoke Worktop Tool. Practical corner radii for bosses and plane surfaces on aluminum-alloy forgings are: 1/32 in. RE: Radius or chamfer? Or we can type ‘FILLET’ in the command bar and presses Enter key to invoke the Fillet command. For a better experience, please enable JavaScript in your browser before proceeding. A bigger radius should be used if part design allows. How do I find the maximum rounding I can apply to either corner for any amount of rounding on the other corner? Find. Misc. Sharp corners should be rounded with a radius measuring between 25 and 60% of the nominal wall thickness. That said, I totally agree with Hotchip, you are better off modeling the fillet with geometry, certainly if it's radius is 10% the size of the object. The red square represents the printed piece and the red curved section represents how the square corner of the printed piece would be rounded off. Ra Roughness μm.
