5mm Sheet Metal Bend Radius

Recommended inside bend radius for sheet metal parts should be equal to material thickness.

5mm sheet metal bend radius.

Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. Otherwise the bending knife will hit the flange. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. To keep it simple i also use a 2 mm inside radius.

Thus the smallest radius of any bend in a sheet should be at least equal to the thickness of the sheet. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. But for harder materials e g.

This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. The problem with bending too tightly. For example a flip hole tapping of a m4 with a 1 5 mm sheet bent the d value should be greater than 8 mm.

You described a rough rule to find a steel s minimum bend radius. We recommend a minimum bend radius of 1t for all sheet metal parts. The minimum bend radius data shown in these charts is measured to the inside of the bend. When the sheet metal is bent a bend radius is required at the bend.

Use this document to choose values that are both manufacturable and meet your needs. Below is xometry s minimum bend radius reference table which is based on. Figure 1 29 bending of the hole flanging tapping. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. Bend radii minimum bend sizes. Let s say i have a 2 mm thick sheet and i want to bend it. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form. Discover all our calculation tools in the calculators section of the top menu. The most common problem with bending a piece of sheet metal too tightly is. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

For example if the thickness of the sheet is 1 mm the minimum bend radius should be 1 mm.
