THE IMPACT OF AREA AND SHAPE OF TOOL CUT ON CHAIN SAW PERFORMANCE
Rudarsko-geološko-naftni Zbornik, 2016 The cutting design of the chain saw is defined by the number, the arrangement and the geometry of the cutting tools. When using chisel cutting tools, the cross sectional area of the cut and the shape of the groove are determined by the width and depth of
