中文拼音 [cūcāozhìzào]
粗糙製造
英文
o rough fabrication-
Roughness may be attributable to the nature of the wall substance and the method of its manufacture.
粗糙度可歸因於管壁材料性質及其製造方法。According to the present personalized needs for product design for manufacturing enterprise, the paper applies rough set theory to simplify irrelevant attributions of product design knowledge, to generate decision - making rules, finding potential knowledge - pattern among products or components in order to classify vague target or to provide design knowledge for the design staff
摘要針對製造業產品設計的個性化需求，將粗糙集理論應用於產品設計知識的屬性約簡和分類規則生成，發現產品或零部件間潛在的特徵知識模式，從而為設計人員所能夠提供的模糊對象進行分類或提供設計知識。Measurement and characterization of surface texture is an important aspect of precision metrology. historically this has involved partitioning a profile into different wavelength regimes referred to as roughness, waviness and form followed by numerical quantization. parameters computed are then inspected for tolerance compliance to ensure a part performs its intended function. this approach is satisfactory when the specification has been carefully determined and the process is stable. however, when the manufacturing process is under development or when instability or modifications to the process invalidate specifications, there is a need to study surface finish parameters in relation to functional performance or process measures. in this context, the problem of surface texture classification and recognition are discussed. advanced techniques developed for this purpose along with applications are presented. also, the techniques discussed here will be useful across large bandwidth, from the characterization of nano scale to traditional micro scale surfaces
表面結構的測量與特徵描述是精密計量技術的一個重要方面，傳統上包括將輪廓情況根據不同的波長范圍劃分為粗糙度、波紋度和形狀及后續的數字量化.按算得的參數檢查它是否為公差允許，以保證零件執行其指定的功能.當技術特性已經經過仔細確定，並且其過程穩定時，該方法是令人滿意的;但是，當製造過程正在進行中或過程的不穩定、過程變化使技術特性失效時，就需要研究和功能表現及過程評定相關的表面參數.討論了表面結構的分類與識別問題.同時闡述了為此目的而開發的先進技術及其應用.所研究的技術對從納米尺度到傳統的微米尺度的較大帶寬范圍內的表面特徵描述都是有效的The crude craft which the wright brothers made in 1903 was the prototype of the modern airplane
萊特兄弟在1903年製造的這個粗糙的飛機是現代飛機的原型。Rapid prototyping manufacturing ( rpm ) and rapid tooling ( rt ) can rapidly fabricate complicated prototypes and various mould & dies of higher dimensional precision and better surface roughness respectively. with those technologies, the objective of rapid product development ( rpd ) can be achieved consequently
快速成型技術（ rpm ）與快速模具製造技術（ rt ）能分別用來快速製造具有復雜形狀的原型及具有高尺寸精度和低表面粗糙度的各類工模具，因而利用這兩種技術能實現快速產品開發的目的。分享友人
