DEVICE FOR MEASURING AXIAL CUTTING FORCE AND TORQUE at DRILLING

摘要

Device for measuring the axial cutting forces and torque at drilling comprises a dynamometer - sensor with strain gauges connected in half-bridge circuits which are connected to the block for amplification and conversion of signals, connected to a data collection device, data are transmitted to a computer. As a block for amplification and conversion of signals a microcontroller containing interconnected four-entry multiplexer, programmed 16-bit amplifier is used, and as a data collection device a converter USB / UART is applied.
