Understanding Bending Allowance and Bend Deduction
One of the most fundamental yet complex aspects of sheet metal design is accurately calculating the bending allowance and bend deduction. These calculations are crucial for ensuring that the final product meets design specifications after bending.
Problem: Calculating Bending Allowance for a Sheet Metal Part
You are required to design a sheet metal part that involves a 90-degree bend. The material is 2mm thick steel, and the internal radius of the bend is 3mm. Calculate the bending allowance.
Solution:
To solve this problem, we first need to understand the concept of bending allowance, which is the length of the arc through the thickness of the material at the bend. The bending allowance can be calculated using the following formula:
BA = (π/180) × (R + K × T) × A
where:
- BA is the bending allowance
- R is the internal radius
- T is the material thickness
- A is the bend angle
- K is the K-factor, which is the ratio of the distance from the neutral axis to the thickness of the material. For steel, K is typically 0.3.
Plugging in the values:
- R = 3mm
- T = 2mm
- A = 90 degrees
BA = (π/180) × (3 + 0.3 × 2) × 90 BA = (π/180) × (3 + 0.6) × 90 BA = (π/180) × 3.6 × 90 BA = (π × 3.6 × 90) / 180 BA = (3.6 × 90) / (180/π) BA = (3.6 × 90) / 57.2958 BA ≈ 5.654 mm
Therefore, the bending allowance for this sheet metal part is approximately 5.654 mm.
Material Selection for Corrosion Resistance
Another critical aspect of sheet metal assignments is selecting the appropriate material based on the specific requirements of the application, such as corrosion resistance.
Problem: Choosing the Right Material for a Sheet Metal Component Exposed to a Marine Environment
You need to design a sheet metal component that will be used in a marine environment, where it will be exposed to saltwater. Select a suitable material and justify your choice.
Solution:
In a marine environment, the primary concern is corrosion due to exposure to saltwater. The material must be highly resistant to corrosion to ensure longevity and structural integrity.
Material Selection: 316 Stainless Steel
Justification:
- Corrosion Resistance: 316 stainless steel contains molybdenum, which significantly enhances its corrosion resistance, particularly against chloride ions found in saltwater.
- Durability: This alloy maintains its strength and toughness even at extreme temperatures, making it suitable for various environmental conditions.
- Maintenance: 316 stainless steel requires minimal maintenance compared to other materials, reducing long-term costs and ensuring reliability.
Modeling and Flattening a Complex Sheet Metal Part in SolidWorks
Creating a complex sheet metal part in SolidWorks involves several steps, including modeling, adding bends, and flattening the part for fabrication.
Problem: Design and Flatten a Complex Sheet Metal Bracket
Design a sheet metal bracket with the following specifications: a base plate with two flanges bent at 90 degrees, each flange with a hole for mounting. The material thickness is 1.5mm.
Solution:
Model the Base Plate:
- Start with a sketch of the base plate.
- Define the dimensions based on the design requirements.
- Extrude the sketch to a thickness of 1.5mm.
Add Flanges:
- Select the edge of the base plate where the flange will be added.
- Use the "Edge Flange" feature in SolidWorks.
- Specify the flange length and the bend angle of 90 degrees.
- Repeat the process for the second flange.
Add Mounting Holes:
- Select the face of the flange where the hole will be located.
- Use the "Hole Wizard" feature to create the hole.
- Define the hole size and position it appropriately.
- Repeat the process for the second flange.
Flatten the Part:
- Use the "Flatten" feature in SolidWorks to unfold the sheet metal part.
- Ensure that all bend lines and features are correctly represented in the flat pattern.
By following these steps, you can create a complex sheet metal bracket in SolidWorks that meets the specified requirements. The flat pattern can then be used for fabrication, ensuring accuracy and efficiency.

Problem: Designing a Heat Shield for an Automotive Application
Design a sheet metal heat shield for an exhaust system in an automobile. The material should withstand high temperatures and provide effective thermal insulation.
Solution:
Material Selection: Inconel 625
Justification:
- High Temperature Resistance: Inconel 625 can withstand temperatures up to 982°C, making it ideal for automotive exhaust systems.
- Thermal Insulation: This nickel-based alloy provides excellent thermal insulation, protecting other components from heat damage.
- Durability: Inconel 625 maintains its strength and structural integrity under extreme conditions, ensuring long-term performance.
Design Steps:
Model the Heat Shield:
- Start with a sketch of the heat shield based on the exhaust system's geometry.
- Define the dimensions and contours to ensure a precise fit.
- Extrude the sketch to create the base structure.
Add Bends and Features:
- Use the "Edge Flange" and "Bend" features in SolidWorks to add necessary bends for fitting around the exhaust components.
- Include cutouts or perforations to enhance thermal dissipation.
Simulation and Analysis:
- Perform thermal analysis in SolidWorks to ensure the design meets the required thermal performance.
- Adjust the design based on simulation results to optimize thermal insulation and structural integrity.
By selecting the appropriate material and following a systematic design process, you can create an effective heat shield for automotive applications.
