Wood Products Online Expo Quad Circular Sawbox X Canter Twin Saw Box X Circular Sawbox Saw Calculator X Horsepower X  Saw Rim Speed (feet per minute) X  Tooth Bite (inches) X  Gullet Area (square inches) X  Gullet Capacity (square inches) X  Gullet Fill Percent X  Saw and Speed Calculator - Circular Sawbox:
 Circular Sawbox Saw Calculator The Saw calculator is used to calculate saw horsepower or feed speed constraints.  Horsepower Feed Speed (feet per minute) x Total Depth of Cut (inches) x Kerf (inches) x Number of Sawlines 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 Rim Speed (feet per minute) Saw Diameter (inches) x 3.1416 ÷ 12 x RPM  Tooth Bite (inches) Feed Speed (feet per minute) x 12 ÷ RPM ÷ Number of Teeth  Gullet Area (square inches) Saw Diameter (inches) x 3.1416 ÷ Number of Teeth x Gullet Depth (inches) x Gullet Area Factor  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 | ||
