Introduction
Oil palm (Elaeis guineensis) is one the most important plantation tree crops in Malaysia and it covers a land area of almost 4.17 million hectares in 2006.
Introduction
Palm oil and its products contributed more than
RM 30 billion in export earnings in 2006
Introduction
However, the total oil palm biomass of almost 46 million tons
produced annually, poses management, utilization and
environment challenges.
IntroductionOne of the most promising product manufactured from oil
palm biomass, especially the empty-fruit bunch (EFB), is
particleboard. However, its acceptance in the market is limited
by its high tool wear characteristics.
Introduction
Therefore, a study was undertaken to evaluate the tool
wearing characteristics of OPEFB particleboard.
Materials & Methods
A series of experiments were carried out using an ANDERSON
MH16 computer numerical control (CNC) router.
Materials & Methods
Single fluted tungsten-carbide router bits (12 mm ø, RPM 22,000)
of 3 different compositions were used in this study.
Materials & Methods
The edge of the router bits were examined after 5000 m of
cutting length – in order to characterize the tool wear
mechanisms.

Discussion
Rate of wear in the former is 80% higher in the initial stage and
gradually reduces to 50% throughout the cutting length.

Conclusion
OPEFB particleboard is almost 4X more abrasive on the tool compared to wood particleboard. The use of harder tool material is highly desirable when cutting this material.
