一、立项背景天然石材因其稳定的物理和化学特性,自古就广泛应用于建筑装饰业。在全国每年2.5万亿建筑装饰总产值中,石材及相关产业产值占据半壁江山。传统的加工方式已远远不能满足人们对石材制品的高档化、个性化、多样化需求。石材属于硬脆性材料,天然石材物理属性的多样性和不均匀性,使石材加工特性与金属加工相比存在本质差别,主要体现在:石材异型制品的曲线 First, the project background Natural stone because of its stable physical and chemical properties, has been widely used in the construction and decoration industry. In the national annual output of 2.5 trillion building decoration, stone and related industries accounted for half of the output value. The traditional processing methods are far from meeting people’s high-grade, individualized and diversified demands for stone products. Stone is a hard and brittle material, natural stone physical properties of the diversity and inhomogeneity, processing characteristics of the stone compared with metal processing, there are essential differences, mainly reflected in: stone shaped products curve
