Grinding System

The paper analyzes the structure of technological fixtures for the positioning and fixing of large-sized thin-walled pyroceram shells as a factor affecting the dynamic characteristics of the grinding system. The solution to the problem of ensuring the dynamic stability of the «mandrel-workpiece» subsystem is necessary to increase the efficiency of shell machining in present conditions. Studying the vibrations frequency spectrum of the technological system during grinding has made it possible to determine their sources. The magnitude and frequency of vibrations depend on the mandrel structure - the clamping fixture. The study results are the requirements for a new mandrel structure, considering the dynamic stability of the technological system.

Set Up

The experimental system of dynamic characteristics is set up to improve the dynamics performance and motion control quality of 2-DOF robot. The vibration acceleration response of the end actuator is measured at different speeds in two directions vertical and parallel to the workbench plane. The frequency spectrum is obtained through frequency analysis to provide a basis to improve the performance of robot.
