The Canter Chip Length Calculator calculates theoretical chip length from arbor speed, number of knives, and material feed speed. Use it to compare how changes in operating settings affect the calculated chip length.

• Enter the arbor speed in revolutions per minute (rpm), the number of knives, and the feed speed. Select Imperial for feed speed in feet per minute and chip length in inches, or Metric for feed speed in metres per minute and chip length in millimetres. The result updates when you finish editing an input.
• Increasing feed speed increases calculated chip length. Increasing arbor speed or the number of knives decreases it. Results are displayed to three decimal places.
• Select Reset to restore the default Imperial settings, or Print to produce a report of the current inputs and result. The calculation assumes evenly spaced knife engagements; actual chip dimensions can vary with cutting geometry, wood characteristics, and operating conditions.

Chip length is calculated as:

• Imperial: Chip length (in.) = Feed speed (ft/min) × 12 ÷ (Arbor rpm × Number of knives)

• Metric: Chip length (mm) = Feed speed (m/min) × 1,000 ÷ (Arbor rpm × Number of knives)
