Abstract: Grinding wheels are tools used to form precision components and continue to be used to increase production rates due to their ability to remove high volumes of material at high speeds. There is a demand to increase the speed of rotation of the grinding wheel in order to achieve high removal rates, especially with vitrified grinding wheels. The increase in speed creates a situation where the grinding machine and the operator are subjected to a possible catastrophic failure of the wheel due to the stresses generated in the coarse brittle structure of the vitrified grinding wheel. Calculations were conducted to determine maximum stress in parallel-sided and recessed cup wheels. Relevant factors of safety and bursting speed were also calculated and compared with experimental data. The paper proves the usefulness and applicability of a method developed for taking account of stress concentrations at the recess of small cup-shaped grinding wheels.
