Abstract

The International standard defines leather thickness to be the value recorded 5 seconds after the start of the measurement under a constant pressure of 500g/cm2. We have developed specialized computer software to achieve the 5-second delay and constant pressure thus avoiding human errors in practice. Our software can accurately determine the starting time of the measurement and lock the valid data point automatically. By using the software in our digital leather thickness measuring device with independent intellectual property rights, we are able to measure the leather thickness in a completely automatic fashion for the first time.We report satisfactory experiment results. Furthermore, our device is portable and can be used in any production situation.
