This study demonstrated a process control strategy for extending tool life in wood-based machining. A feedback control technique regulated tool spindle speed while cutting to maximize tool performance. Machining of melamine-coated particleboard was conducted on a computer numerical control router with tungsten carbide inserts. Four cutting scenarios were applied: constant low spindle speed, constant high spindle speed, step function cutting and cutting using feedback control technique. After each test, panel chipping and tool wear were assessed to determine the effect of varying the spindle speed on tool wear and panel chipping. The findings indicated that although tool wear increased, panel chipping decreased when the spindle speed remained continuously high. A constant low spindle speed increased panel chipping and decreased tool wear. Raising the spindle speed in the step function setting reduced tool wear and panel chipping, but it was not apparent when these speed adjustments should be made. The feedback control technique greatly extended the tool life, improving surface quality. The study contributes significantly to wood-based machining procedures and greatly impacts the woodworking sector. The advantages of improved tool life and increased productivity justify the need for more research in this area.
