Abstract
On machines of the milling group, various operations are performed for processing metal workpieces with end, end, groove, and cylindrical cutters. Using cutting tools and devices, thread cutting operations are performed. One of the main sources of noise that exceeds sanitary standards is the “cutting tool – workpiece” system. The article presents theoretical studies and derives analytical dependencies of sound pressure and sound power levels for technological processes of milling and planing, and obtains expressions for vibration speeds. The presented approach is distinguished by the simplicity and logic of the engineering calculation of sound pressure levels, taking into account the natural frequencies of vibration of the cutting tool and the workpiece over the entire standardized frequency range.
