The minimum bend radius (MBR) for sheet metal is the smallest inner radius achievable during bending without causing material cracking,

The rule of thumb for sheet metal refers to practical design and processing guidelines accumulated from experience, simplifying complex engineering

The five key sheet metal operations are shearing, bending, punching, drawing, and forming. Shearing cuts sheets to size; bending shapes

The core difference between sheet metal parts and machined parts lies in raw material form and processing methods: sheet metal

The 4T rule is a core guideline in sheet metal design to ensure bending accuracy, requiring functional features (e.g., holes,
