Abstract:The carbon fiber reinforced plastics (CFRP) is a typical difficult cut material since it has high hardness, anisotropy and non-homogeneity. It is easily delaminated and the wheel is loaded during grinding. An electroplated grinding wheel with controlled abrasive clusters is developed to meet the requirement of dry grinding of carbon fiber/epoxy resin composite parts. And the dry grinding experiments of carbon fiber/epoxy composites are conducted with reference to a conventional electroplated grinding wheel. The experimental results show that the steady axial force and good surface integrity are obtained by using the new grinding wheel with controlled abrasive clusters, and the surface roughness Ra of the workpiece is kept in a range from 0.8 μm to 1.3 μm. The spaces among the abrasive clusters serve as the rooms and accesses for accommodating and removing the grinding chips, which are beneficial to avoid wheel loading effectively. The new grinding wheel with controlled abrasive cluster can be used for dry grinding of large carbon fiber composites parts.
