The schemes analysis of profile milling of long and non-technological workpieces

The article considers alternative schemes of profile milling of long non-technological workpieces – of the peripheral segments, formed during longitudinal opening of logs. Peripheral segments are a large waste of manufacture and contain the wood fibres with high physics-mechanical and operational properties. Therefore manufacturing qualitative wood products from peripheral segments is especially actual problem. However, the named workpieces are characterised by low adaptability to manufacture, therefore working out and the analysis of the machining schemes, expelling a resonance in technological system are necessary. The non-resonance machining scheme is used in a design of the milling machine tool PFP-100 for profile milling of a large wood waste.
