The Canter Chip Head Feed Speed and Horsepower (HP) Calculator estimates the power required, or feed speed restriction to remove a segment of wood from a round log with a chipping head. It uses log diameter, depth of cut, feed speed, arbor drive efficiency and wood species to calculate horsepower or kilowatts.

• Enter the log diameter and depth of cut to define the material being removed. Depth of cut is measured inward from the log’s outer surface. Set the feed speed and arbor drive efficiency, then select a wood species. The calculator uses the selected species’ stored density value.
• Results include wood density, cant face width, chipping area and required power. Cant face is the width of the flat surface created by the cut. Chipping area is the cross-sectional area of wood removed. Required power accounts for the entered drive efficiency.
• Switch between Imperial and Metric units to convert inputs and results. Imperial results display horsepower, while Metric results display kilowatts. Calculations update after an input is edited and confirmed or a different species is selected. Use Reset to restore the default values and Print to produce a summary of the inputs and results.
• Power requirements are estimates based on the calculator’s geometric model, stored species densities and power formula. Actual requirements also depend on wood condition, knife condition, cutting geometry and machine configuration.Feed Speed
