The disclosure relates to surface roughening methods in which a cutting
tool having a radial cutting blade with first and second cutting edges is
fed along a longitudinal axis of an article while rotating the cutting
tool about the axis. The first cutting edge forms a first machined
pattern of peaks and valleys on a surface of the article, and the second
cutting edge removes at least a portion of the peaks to form roughened
fracture surfaces in a second machined pattern defining an arrangement of
grooves, corresponding to the valleys, separated by lands, corresponding
to the roughened fracture surfaces. The disclosure also provides cutting
tools useful in practicing the surface roughening methods. The disclosure
further describes cylindrical articles having interior or exterior
surfaces roughened using the methods. The methods, cutting tools and
articles have applications including fabrication of cylinder blocks for
internal combustion engines.
