Special Issue "Advanced Manufacturing Technology and Systems"
Grinding experiments are conducted to study the grinding force and the material remove of laser-structured zirconia ceramic. Results show that the grinding forces in tangential and normal direction are significantly reduced. Compared to the grinding surface without laser-structured, a damage-free grinding surface is obtained by laser assistance.

SDM – Rhosonics
The SDM uses a non-intrusive ultrasonic sensor to measure the real-time density of mineral slurries under high-density levels and at very large pipes. By measuring the acoustic impedance of a slurry, the SDM calculates the density of the slurry in real-time during the process. The sensor is made of stainless steel and ceramic material.
