Horsepower

Feed Speed (feet per minute) x 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

More ...
 
Tooth Bite (inches)

Feed Speed (feet per minute) x 12 ÷ RPM ÷ Number of Teeth

More ...
 
Gullet Area (square inches)

Saw Diameter (inches) x 3.1416 ÷ Number of Teeth x Gullet Depth (inches) x Gullet Area Factor

Note: Gullet Area Factor = .42 for square back tooth .52 for round back tooth

More ...
 
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).
