Abstract: This paper focuses on building and analysing computer models of grinding wheels with recessed features spinning at different rotational speeds. By employing a computational approach, it was possible to determine the maximum principal stresses in the wheel together with the location of those stresses. The geometry of vitrified wheels considered included a plain-sided rotating wheel and a recessed large cup 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 large cup-shaped grinding wheels.

Keywords: vitrified grinding wheels; numerical analysis; bursting speed; mechanical stress; large cup wheels; safety.
