Within a pulp industry production process, a drop in the performance of a wood log rotary debarker
was identified. Such loss of performance was due to the occurrence of excessive wear of the device’s
cutting blades, requiring their regular and premature replacement. The material used to manufacture
the cutting blades, Hardox 500, has characteristics considered adequate for the required use. However,
it was concluded that the blade manufacturing process degraded its mechanical properties, leading
to its premature wear when placed in service. The present study intends to propose, characterize, and
validate an alternative cutting process to manufacture the debarker’s cutting blades. Abrasive waterjet
cutting technology was proposed to produce the cutting blades. The suitability of this manufacturing
process is discussed considering the specified geometry and the material characteristics of the resulting
cutting blades.
