摘要：

This　paper　analyzed　the　large　diameter　Fresnel　lens　mold　machining　mechanism　based　on　modal　test　methods.The　design　and　mold　machining　principle　of　Fresnel　lens　were　introduced.　Explored　the　cutting　speed　and　feed　on　chip　formation　process.　The　results　show　that:　the　material　strength　and　plastic　brittle　have　significant　impact　on　chip　morphology　in　the　H62　brass　mold　processing,　an　improvement　of　material　strength　with　the　increase　of　strain　rate　and　the　evolution　process　of　the　chip　can　be　divided　into:　ribbon　cuttings,　serrated　chips,　cell　chips.　©　(2014)　Trans　Tech　Publications,　Switzerland.
