## What is SheetMetal Master?

Sheet Metal Master is one of the TFC Mechanical Engineering Masters series tools developed by LinkReady team, specifically designed for sheet metal engineers, designers and technicians.

Based on empirical formulas, this application provides professional sheet metal unfolding calculation functions. Whether it's simple bending or complex shapes, you can quickly and accurately calculate unfolded dimensions, greatly improving sheet metal processing efficiency.

The core features of Sheet Metal Master include:
- Bend allowance calculation: calculate unfolded length based on parameters such as bending angle and sheet thickness
- K-factor calculation: determine appropriate K-factor values based on materials and bending conditions
- Complex shape unfolding: support unfolding calculation for various common sheet metal shapes
- Simple interface: intuitive operation and fast response, suitable for on-site use

As an important member of the TFC Mechanical Engineering Masters series, Sheet Metal Master, together with other tools (such as Tolerance Master, Thread Master, etc.), forms a complete mechanical engineering calculation solution. All tools are developed by professional mechanical engineers to ensure the accuracy and reliability of calculation results.
