Optimizing the cutting of tension wood in Rubberwood: an economic and quality perspective

A study was carried out to measure the cutting force and the resultant machined surface quality for tension wood and normal wood of Rubberwood using a single saw tooth experimental set-up. Three different saw tooth geometries were used in the experiment, to establish the optimum saw tooth design for...
