Adaptive command for circular saw

Sawing with circular saw is not possible to realize with optimal cutting parameters because the continuing variation of contact lengths of wing chord between cutting tool and the material. On coming in and coming out of teeth´s in material appear the possibility to break off this teeth´s, but in the middle of cutting this possibility is decrease because are much more teeth´s in contact. So the optimal saw will be with adjusting cutting parameters when we can assure the protection of teeth´s and we can obtain the maximum capacity of saw. This two facility we can obtain by adaptive command of circular saw. In the paper is present the working scheme and the algorithm of adaptive command. Adaptive command have like reference measure the power maximum admissible on teeth like the teeth will do not break and the adjustable measure is the cutting feed of saw blade. In this case is used the maximum cutting capacity of tool.
