- Abstract
This article examined the impact of cutting speed and feed rate on the process of cross cutting with a saw chain. Three cutting speeds and three feed rates were chosen, and their impact on energy intensity was evaluated. The measurements were performed on an experimental device, on which it is possible to set the rpm (cutting speed) and the feed rate into the section using frequency converters. The cutting speed influences the resulting energy efficiency, at a cutting speed (vc) of 5.02 m × s-1 the resulting power (P) was 485 W. With increasing speed the cutting power increased, where the maximum value of P was 619 W at a cutting speed of 6.81 m × s-1. At a feed rate of 0.286 m × min-1 the cutting power was 376 W, with increasing cutting speed the cutting power (P) also increased almost linearly up to the value of 695 W at a feed rate (vf) of 0.857 m × min-1. The results showed that the cutting speed and the feed rate have a clear influence on the process of cross sawing with a saw chain.
