This paper presents an experimental investigation on
the machinability of lasersintered material using small ball end mill focusing on wear mechanisms. Lasersintered material was produced
by irradiating a laser beam on a layer of loose fine SCMNiCu powder. Bulk carbon steel JIS S55C was selected as a reference steel.
The effects of powder consolidation mechanisms and unsintered
powder on the tool life and wear mechanisms were carried out. Results indicated that tool life in cutting lasersintered material is
lower than that in cutting JIS S55C. Adhesion of the work material and chipping were the main wear mechanisms of the ball end mill in
cutting lasersintered material. Cutting with the unsintered powder
surrounding the tool and lasersintered material had caused major fracture on the cutting edge.
