Abstract

Grinding tools like one side recessed grinding wheels are used in many machining applications and must provide a high reliability against fracture concerning safety-relevant and economic aspects. The calculation of the bursting speed on the basis of the mechanical properties is an important tool for the design of grinding wheels. However, no equation is available to estimate the bursting speed of these types of grinding tools so far. For the calculation of the bursting speed of one side recessed grinding wheels a parametric study using FEA was carried out. The results of these investigations provide the basis for a geometric function, which allows in association with a newly-developed fracture criteria to calculate the bursting speed of one side recessed grinding wheels. For the validation of the developed concept spin burst tests with grinding wheels of eight different geometries and two granulations were carried out. The results of these investigations show a very good correlation of the calculated and measured bursting speeds for all tested types of grinding wheels.
