Q2. K factor of sheet metal
Ans. 
The K factor of sheet metal is a constant used in sheet metal bending calculations to determine the amount of material elongation and compression.
• The K factor is influenced by the material's properties, thickness, and bending method.

• It is used to calculate the bend allowance, bend deduction, and flat pattern dimensions.

• A higher K factor indicates more material elongation and compression during bending.

• Common K factor v...read more
