Bending Sheet Metal is a free Android utility tool developed by Sotnikov. It is designed to calculate the total flat length based on the K-factor you specify. The program is especially useful for metal fabricators and sheet metal workers who need to accurately calculate the flat length of sheet metal before bending it.

The calculator is straightforward to use. If you know your K-factor, simply input the value, and the program will calculate the total flat length for you. However, if you are unsure of your K-factor, the program offers approximate values based on the method of bending and stiffness of the material. This feature is especially useful for those who are new to sheet metal fabrication or are working with a new type of material.

Overall, Bending Sheet Metal is an excellent tool for sheet metal workers who need to accurately calculate the flat length of sheet metal. It is easy to use and features a helpful approximate K-factor calculator for those who are unsure of their K-factor value.
