Diagnosing the porosity and liquid permeability of large-pore grinding wheels

Niżankowski C.

Journal of Machine Engineering

2008

Vol. 8, No. 2

86--94

The paper presents a new method of diagnosing the porosity and liquid permeability of large-pore grinding wheels, consisting in the application of computer tomography, image analysis and finite elements method. This method was developed at the Faculty of Mechanical Engineering, Cracow University of Technology in 2006, and is covered by patent protection (P-382829). The method enables diagnosing the grinding wheel porosity not only as regards the percentage share of pores in entire grinding wheel capacity but also their number, shape, length and net of small ducts made by them. It also makes it possible to diagnose permeability of a large-pore grinding wheel without the need to run labour- and cost-consuming experiment tests.
