Minor cutting edge force contribution in wood bandsawing

Abstract As the sawmill industry is moving towards thinner bandsaws for higher yields, it important to study cutting force in more detail. The can be split into two zones. Zone I concerns on major edge as well friction first flank. II considers forces minor edges flanks. significantly affect and has not been studied great Frozen, non-frozen dry heartwood of Norway spruce Scots pine were cut using different tooth geometries was measured. edge, clearance, band thickness, angle clearance investigated. y-intercept force–width graph used (at this point are assumed zero). contribution studied. results show that frozen wood less elastic spring-back therefore cutting. Dried showed a degree (55−75% force). Changing from 2.87 mm 1.6 resulted 10–15% contributions.
