Abstract: The mechanism of ultrasonic assisted grinding is presented. Single factor experiment method was used to conduct experiments in order to reveal the effect of different grinding parameters (including feed rate, spindle speed, grinding depth) on surface roughness and grinding force of optical glass in ultrasonic assisted grinding and conventional grinding. The experiment data wss analyzed and it shows that the surface roughness and tangential grinding force decrease while the axial grinding force increase in ultrasonic assisted grinding process than that in conventional grinding process.

Abstract: A new system for measuring a tangential grinding force using the slip of the rotational speed of an induction motor was developed. The motor slip is measured as the change in the rotational period for the induction motor. The system operates LabVIEW software on a personal computer, and a rotary encoder is connected with the motor spindle, which drives the axis of a grinding wheel. A signal of one pulse per rotation from the rotary encoder is input to the interface of the computer to measure the rotational period. LabVIEW has the flexibility of a programming language and operates within a graphic environment in compiling the signal, analyzing measurements, and displaying analysis results. Thus, the present system is simpler than previous development tools. This work conducts a grinding experiment using the developed system to verify the sensitivity and response in measuring the motor slip. As an example of application, semidry grinding is investigated by measuring tangential grinding forces. Hence, we demonstrate the effectiveness of the developed system for data processing in the analysis of grinding phenomena.
