A mint is an industrial facility which manufactures coins for currency. During final stages of production a coin typically moves and rubs against other coins (its like an ocean of coin.)
The Study was done to measure surface roughness and quantify scratch created during various processes in the production line. As Nanomap-LS can precisely scan and generate 3D imaging of more than 150X150mm area, it was used to scan the entire top surface of the quarter. From the scan surface roughness, defects etc. values were calculated.
