Abstract
Machinability tests were conducted on some local wood species
(Eucalyptus, and Casuarina), as well as date palm leaves’ midribs as one of
the non-timber locally available resources. For comparison, the widely
known Beech wood was included in the research. Turning was carried out in
both longitudinal and cross feed directions using high speed steel tool.
The relationships between the machinability criteria (cutting forces,
cutting temperature, tool life) and the machining variables (cutting speed,
feed, depth of cut) were obtained.
The results indicate that from the viewpoint of the cutting force and
consumed power, Eucalyptus, Casuarina, and DPLM can be machined
easily using conventional wood working machine tools, designed for wide
known commercial woods (e.g., Beech). from the tool life viewpoint
Eucalyptus and Casuarina have a reasonable tool life using HSS, compared
with Beech. But, in case of DPLM the tool life is too small, so that, it is
better to replace HSS tools by harder tool materials as cemented carbides in
cutting of DPLM.
