SURFACE ENHANCEMENT OF CARD
CUTTING IN TEXTILE INDUSTRY BY LASER
SHOCK PEENING

Laser finds its wide application in surface modification due to its peculiar
properties such as high intensity, small spot size etc. Among which La-
ser shock peening (LSP) is an effective surface treatment process which en-
hances the service life of engineering components operating under dynamic
loading. The process involves in generation of shock waves that induces sur-
face compressive stresses into the substrate. Variations in the processing
parameters alter the depth and magnitude of the residual stresses. These
deep compressive residual stresses increase the resistance of materials to
surface-related failures and enhance its hardness.
It was reported that the initial applications of laser shock peening have been
for gas turbine engine blades and components used in the aerospace indus-
try, because of the critical need for better fatigue performance and damage
tolerance. The laser shock peening Technology also shows great potential in
the automotive/truck, medical device/orthopedic implant, and industrial ma-
chinery industries. My current research is focused on applying laser shock
peening (LSP) technique to card cutting in textile industry. The card cutting
wire is similar to that of saw blades so my current presentation focuses on
the commercially available saw tooth blades.
