The production of glass fiber-reinforced polymer
(GFRP) composite parts for engineering applications often
requires drilling holes in these composite parts for assembling
purposes. However, drilling can cause different types of part
failure, one of those failures being delamination. The risk of
delamination can be reduced by selecting appropriate
technological parameters to ensure low cutting forces, that
affect delamination. This paper presents the results of an
experimental study investigating the relationship between
cutting force and technological parameters of drilling (vc and fz)
for GFRP composites. Four types of GFRP samples were used
in the study, differing with respect to weight fraction ratio of a
reinforcement material, fiber type (twill woven and plain
woven) and manufacturing technology. A 2-edge carbide
diamond coated drill with a diameter of 12.726 mm was used in
the tests. Measurements of the cutting force component Fz in the
drilling process conducted with variable technological
parameters were made on a special test stand, 9257B from
Kistler. Based on the study, it can be concluded that drilling
conducted with lower values of technological parameters results
in a lower value of the cutting force component Fz.
