The following table delineates the minimum distance guidelines specific to the relationship between a curl and other features such as holes and bends in sheet metal fabrication.To ensure successful bending, it is recommended to place holes away from bends at a distance of at least 2.5 times the material’s thickness (T) plus the bend radius (R). For slots, it is recommended to position it at least 4 times the .
To avoid workpiece failure, DFM guidelines recommend a minimum distance (D1) from hole to the sheet edge equal to at least the plate thickness (T); we recommend a safe design zone of 1.5 to 2T. Also, when piercing multiple . To calculate how close a hole can be to a bend, you need to use a different formula. In most cases, minimum hole bend distance equals 1.5 times sheet thickness plus bend radius, though the multiplying factor may increase .General Tolerances. If a drawing or specification sheet has not been provided by the customer, Xometry will manufacture the product from the model to the specifications listed below: . Holes should be placed away from the curl at least a distance equal to the radius of the curl plus the material’s thickness. Bends should be at least six times the material’s thickness plus.
Bends are the most typical feature of sheet metal parts and can be formed by a variety of methods and machines which negate the absolute need for some of the below tips. . From edge to extruded hole, distance should be at least 3 times material thickness. From bend to extruded hole, distance should be 3 times material thickness plus bend radius.

Sheet Metal Material Thickness Range. Because sheet metal parts are manufactured from a single sheet of metal, the part must maintain uniform wall thickness. Sheet metal thickness ranges from 0.024 in. (0.609mm) to 0.250 in. . Minimum distance between the bend and hole (Fig. 2) When a workpiece is to be formed, minimum hole size relates to material thickness and bend radius. Maintaining a minimum distance between the bend line and the .

I've always eyeballed the distance from a hole to a bend. But I feel like that rule of thumb should be based on bend radius, material thickness, and measured from the tangent - not the bend line. For instance, there's no way I could put a 3mm hole only 9mm from the bend line on a part with a 20mm bend radius. Notching is a shearing process that removes a section from the outer edge of the part. Distortion may occur if the distance between the notches and the bend is too small. To avoid this, the notch-to-bend distance should be at least 3 times the sheet thickness plus the bend radius. Notches must be at least 3.175 mm away from each other. Minimum Distance Guidelines* Between hole and a bend: ±2.5 times the material length + bend radius: Between a slot and a bend: . Outlined below are the minimum distances to be maintained between a gusset and other features like edges and holes in sheet metal components. These guidelines are calculated considering the material thickness and .
If the distance between the closest hole to the bend line and the bent edge is less than the minimum required distance, deformation may occur after bending. To meet the product requirements, you can refer to Table 1-15 for potential solutions. . This article demystifies the crucial role of fabrication holes in sheet metal bending. You'll .Center-to-center distance Center-to-bend distance SHEET METAL GUIDE V2.2 — TOLERANCES. Hems Hems are folds to the edge of a part to create a rounded, safe edge. Hems may be open, flat, or tear-dropped, and . Hole-to-bend distance Hole-to-edge distance Slot-to-bend distance Slot-to-edge distance SHEET METAL GUIDE V2.2 — TOLERANCES. Notches .The parts quoted were two bend sheet metal channels with holes in the top for slugs to weld to. Two parts needed to align together but overall channel dimensions has a bit of forgiveness in fit. Hole dimensions given from the final bent part. They chose to bend the part and machine the holes after since hole locations needed to be accurate

Small holes in sheet metal can be punched or can be laser cut, depending on the equipment used for punching. As general guideline suggests , hole diameter equal to sheet thickness can be punched. . Hole distance to bend. Hole distortion near the bend- A hole that is punched near the bend line may turn into an unintended bend relief. If hole . For hardware insertion, holes must be at least the minimum distance from center of bend to center of hardware insertion hole . of the flange. Be sure to set up your sheet metal rules using our effective bend radii and bend deduction values. These specs can all be found in the Material Details and at the bottom of our bending calculator page.
The distance from the mold point to the bend tangent. . Sight Line. A mark on a flat sheet of metal set even with the nose of the radius bar or a cornice brake. K - factor. A number used in sheet metal work to determine the setback for bend angles other than 90 degrees. Relief hole. A hole drilled at the point at which two bend points meet .Minimum Distance from Extruded Hole to Bend A certain distance must be maintained between extruded hole to bend to avoid metal deformation and fracturing. It is recommended that the minimum distance between extruded hole and bend should be three times the thickness of sheet metal plus bend radius. t = Sheet metal thickness
The minimum distance that holes should be placed from a bend is a function of the material thickness, bend radius, and the hole’s diameter. Holes should be at least 2.5 times the material .
Notching is a shearing process that removes a section from the outer edge of the part. Distortion may occur if the distance between the notches and the bend is too small. To avoid this, the notch-to-bend distance should be . Fig.: Bending specs for 0.040” 5052 Aluminum. Bend Length. The bend length, or width of the flange, is dependent on, wait for it, the material properties: For the 304 Stainless in the previous example, the maximum .
Sheet metal bending can be done using many methods. We discuss those along with springback, bend allowances, k factor, design tips etc. . Hole Distance from Bend. Close-by holes may get warped. If the holes are too . Minimum hole diameter: Avoid holes smaller than the thickness of the sheet metal; smaller holes are harder to punch cleanly and may require secondary processes. Avoid distortion: If holes are too close to a bend, distortion may occur. Ensure that holes are positioned at a sufficient distance from bends and edges to maintain structural integrity. 6.
It is recommended that the minimum distance between the burring hole edge and the bend should be at least 4 times the sheet thickness. Where, A = Minimum distance from a burring hole edge and bend t = Sheet metal thickness

The following formula calculates the minimum distance from the bend at which you can punch or cut a hole, Distance (D) = Sheet Metal Thickness (t) + Bend Radius (ir) + Diameter of The Hole. So, from the formula, it is clear that the distance is proportional to the sheet metal thickness, bend radius and diameter of the hole. How to Design Screw Holes in Sheet Metal Parts. There are a few different ways to approach holes that screws will pass through in your design. The relationship between the diameter of the hole in your part and the diameter of the threaded portion of your screw or bolt is very important. . and the “Minimum distance from center of bend to .
Welcome to Kreatorzone! On this sheet metal design series you will find the recommended Minimum Distance from Extruded Hole to Part Edge.DISCLAIMER:Do not us. When a bending line intersects at a single point or approaches the edge of the sheet metal within a distance less than twice the material thickness, fabrication holes become necessary. These holes alleviate stress concentration and prevent undesirable material drawing or tearing during the bending operation.

This will minimize the hole distortion. Reply reply jikla_93 • Or just design it so the holes are the appropriate distance from the bend radius Reply .
A machine used to bend sheet metal with various drive types (hydraulic, pneumatic, mechanical, electric). . Hole to Edge Distance: Put holes at least two times the material’s thickness away from the bend. This stops the areas around the holes from changing shape. Make sure holes aren’t too close to where the bend will be to keep the .I have some 0.015" sheet metal that I need to bend into a near circle (5" ID) - that I'm looking to bolt onto a cylindrical surface (5" OD) conformally. I am looking to pre-drill out the holes while it is flat, bend it, and bolt it in place - the cylinder has bolt holes at 0,90,270,180 degrees.The sheet metal thickness is 0.08", bend radius is 0.05". Reply reply . The rule of thumb is minimum distance from outside edge of a hole to the inside material face is equal to 2 times the material thickness plus the bend radius. Reply reply Joaquin2071 .
