New design guidelines for guided circular saws
Optimisation of saw thickness and feed speeds can be determined by trial and error, but the results are most often specific to the particular conditions in that sawmill, and not generally applicable to other mills. Models have been developed for guided circular saws to calculate critical speeds, however they did not yield the desired predictability.
The inability to predict the effects of critical speeds and the onset of the flutter zone has been a major productivity issue for sawmills.
Ahmad Panah, a wood machining scientist at FPInnovations, has developed a refined model for guided circular saws that would correctly predict the onset of the flutter vibration and good cutting performance at critical speeds. This research has resulted in the creation of a set of charts and tables to assist mill personnel in evaluating their saws.
