Experimental studies results of influence of wood-milling shank cutters constructions on noise level

Abstract

In the article results over of experimental research of levels of voice pressure (air noise) are brought in a process to treatment of wood of different breeds, and also arboreal materials by the end milling cutters of two different constructions: with continuous and irregular canals taking of shaving from the area of cutting. Experiments realized at the facility, established on the basis of the machining center CNC ROVER B 4.35 (BIESSE, Italy). Continuous drainage channel chip is exposed to high sound pressure levels, both at idle and during cutting. The largest air noise occurs during the cutting of oak (95.3 dBA), and the smallest – MDF (80.9 dBA).
