Wood Products Online Expo Quad Bandmill X Canter/Twin Bandmill X Bandsaw Calculator X Horsepower X  Saw Surface Speed (feet per minute) X  Tooth Bite (inches) X  Gullet Area (square inch) X  Gullet Capacity (square inches) X  Gullet Fill Percent X  Saw and Speed Calculator - Bandmills:
 Bandsaw Calculator The Saw calculator is used to calculate saw horsepower or feed speed constraints.  Horsepower Feed Speed (feet per minute) x Depth of Cut (inches) x Kerf (inches) x Specific Gravity x 100 ÷ 144 ÷ Arbor Drive Efficiency (percent) x 100 Note: Specific Gravity: Douglas Fir = .45, Oak = .60, Southern Yellow Pine = .47, Spruce = .37, Oak = .60 Saw Surface Speed (feet per minute) (Band Wheel Diameter × 3.1416 × Wheel RPM) ÷ 12  Tooth Bite (inches) (Feed Speed (feet per minute) × 12) ÷ ((Band Wheel Diameter (inches) × 3.1416 × RPM) ÷ Tooth Pitch (inches))  Gullet Area (square inch) Tooth Pitch × Gullet Depth × Gullet Area Factor Note: Gullet Area Factor = .42 for square back tooth .52 for round back tooth Gullet Capacity (square inches) Gullet Area (square inches) ÷ Sawdust Expansion Factor Note: Sawdust Expansion Factor: 1.8 to 2.0 for slow growing species (ie. Northern Spruce), 2.5 for fast growing species (ie. Southern Yellow Pine).  Gullet Fill Percent Depth of Cut (inches) × Tooth Bite (inches) x Sawdust Expansion Factor ÷ Gullet Area (square inches) × 100 Note: Sawdust Expansion Factor: 1.8 to 2.0 for slow growing species (ie. Northern Spruce), 2.5 for fast growing species (ie. Southern Yellow Pine). | ||
