Latest Patents

Tae Hun Lee holds a patent for a "Strain sensor-based workpiece processing monitoring method and system for same." This invention involves attaching strain sensors to a workpiece and measuring the resistance values of these sensors over time while cutting the workpiece with a milling cutting machine. By applying Fourier transformation to the measured resistance values, a power spectrum in the frequency domain is obtained. This spectrum allows for the identification of a power peak, which indicates the magnitude of vibration occurring during the machining process. Additionally, by attaching a strain sensor to a stamper of a plastic working machine, the resistance value is measured while pressing a workpiece on a die. The corresponding plastic working force can be derived from the magnitude of the strain related to the measured resistance value. This method enables high-precision monitoring of the plastic working and cutting processes at a low cost.
