摘要：

In　view　of　the　cutting　speed　reduced　and　cutting　quality　became　poor　because　cutting　front　changes　to　flat　and　amount　of　lag　changes　to　large,　light-gas　eccentrically　cutting　method　was　proposed.　Through　the　experiment　and　analysis　of　the　results,　the　conclusion　can　be　obtained　that　when　laser　beam　is　before　gas　jet,　cutting　speed　can　be　improved.　While　offset　distance　have　impacts　to　cutting　result.　If　the　offset　distance　is　too　small,　it　has　no　difference　with　light　-　gas　coaxial　cutting;　if　the　offset　distance　is　too　large,　it　weakens　the　gas　jet　at　the　cutting　surface,　which　is　not　conducive　to　cutting.　It　can　achieve　the　best　results　when　the　offset　distance　is　0.3mm.The　cutting　quality　with　1.5mm　diameter　nozzle　is　better　than　that　of　2mm.　Therefore　within　the　allowable　range　in　the　offset　distance　the　nozzle　aperture　should　be　reduced.　©　(2014)　Trans　Tech　Publications,　Switzerland.
