Abstract : This paper investigates tool wear mechanisms of a ball end mill in cutting laser sintered material. Cutting edge temperature is measured
by using a three-color pyrometer with an optical fiber. Bulk carbon steel JIS S55C is selected as the standard steel. Experimental
results show that tool life in cutting sintered material is shorter than that in cutting JIS S55C. Observations by SEM show that adhesion of
the work material and micro chipping are the main wear mechanisms in cutting sintered material. The corresponding cutting edge temperature
shows a continuous increase as wear evolves with cutting time.
