Study of Surface Roughness of Cutting Isothermally Hardened Ductile Iron in Tosa Knife Forging Technique Based on Intelligent Calculation

With a long history of more than 600 years development, the Achang Tosa knives have always been handmade and made in strict accordance with tradition absorbing essence foreign cultures. It is not only tool or gift, but also “knife culture” local “folk ethnic characteristics Yunnan. In this paper, we begin our research on by compiling literature conducting field to investigate jointly created neighboring groups studying forging process knives. Three sets specimens were prepared mechanical properties determined combining existing isothermal quenched ductile iron (ADI) material production, high-speed cutting test was carried out CC650 ceramic relationship between machined material, dosage-surface roughness during ADI; based particle swarm algorithm, theoretical model surface parameters established provide guidance for optimal production ADI cutting. provides valuable experience protection intangible cultural heritage minorities reference development unique crafts other minorities.
