【正文】 edge modeling and strategic planning prehensive stamping process was studied. In stamping design including all kinds of knowledge, such as domain knowledge, multitasking knowledge, nonstandard knowledge. Each kind of knowledge all need to be integrated into the system. Stamping mould that is the core of stamping process. Must consider the various factors, such as geometry, technical requirements, material properties and stamping feasibility, working procedures arrangement, the structure of mould tool. Stamping process planning is a kind of creative program based on experts39。 在工藝規(guī)劃中協(xié)助設(shè)計(jì)者的此系統(tǒng)將會(huì)是一種有用的工具。用戶在設(shè)計(jì)過程中可以自由使用它們作為參考。力方程是由知識(shí)規(guī)則庫(kù)的推理得到的。設(shè)計(jì)的第一部是得到工具的工作區(qū)域。依靠知識(shí)模型的數(shù)據(jù)結(jié)構(gòu)，通過移動(dòng)點(diǎn)和改變步驟，增加空步和刪除空步的目的可以被實(shí)現(xiàn)。為了使設(shè)計(jì)過程更方便，可以把矩陣中的上半部分元素置零。布局智能設(shè)計(jì)的核心是開發(fā)干涉點(diǎn)的智能模型 [13]。 p = {. . ., (ki , kj), . . .} ki , kj ∈ K, 1 ≤ i, j ≤ n(i _= j). (2) 每種類型的精確信息通過相關(guān)矩陣被保存在知識(shí)模型中。此精確信息應(yīng)該在帶狀布局知識(shí)庫(kù)中得到 。此模型中的預(yù)處理模塊，包括定位產(chǎn)品模塊和從產(chǎn)品模塊中提取精確的信息。材料利用率在當(dāng)前角度下被計(jì)算出來。每對(duì)元素中間的距離需要重新補(bǔ)償。當(dāng)參數(shù)有所改 變時(shí) ，布局 規(guī) 劃 圖 可以被更新。 圖 三所示 為 平面布局的等 級(jí) 體系 結(jié) 構(gòu) 第一種模式的作用是 選擇 粗略數(shù) 值 和 計(jì) 算工作區(qū)域的 總 體 輪 廓。零件的形狀可以在知識(shí)模型中修改。 3 模型的智能推理過程和零件的規(guī)格相比有一定限度范圍的工藝參數(shù)。知識(shí)庫(kù)由 CAD軟件支持。它幾何了不同模型的優(yōu)點(diǎn)且能滿足幾何設(shè)計(jì)和推理過程。由于零件的數(shù)據(jù)信息不能被完整的描述、數(shù)據(jù)分離水平太低， 幾何模型被特征模型取代。每一種知識(shí)都需要集成到該系統(tǒng)中。 [8].智能系統(tǒng)是一種計(jì)算機(jī)系統(tǒng)，它試圖代表人類知識(shí)和專業(yè)知識(shí) , 以一種實(shí)際 2 和有效的途徑提供快捷、方便的知識(shí)。 [6].他們的研究集中在分解較小的橋型廢料的形狀編碼和識(shí)別技術(shù)。 [3] 實(shí)施 以知識(shí)為本的冷成形序列設(shè)計(jì)系統(tǒng)，采用設(shè)計(jì)規(guī)則確定建立一個(gè)可行的序列，然后使用有限元分析優(yōu)化這個(gè)序列。 它 是金屬成型應(yīng)用的一個(gè)重要組成部分 ，它與生產(chǎn)質(zhì)量、成本、生產(chǎn)率和工具壽命有直接的影響。 對(duì) 有 些 關(guān)鍵技術(shù) 如 沖壓工藝的可行性 、排樣的 最佳算法 、 智能地帶的布局和內(nèi)力計(jì)算進(jìn)行了研究。 [1].對(duì)于冷鍛序列的設(shè)計(jì)開發(fā)了一種基于 PC 的專家系統(tǒng)，該系統(tǒng)采用基于塑性理論和實(shí)際考慮的規(guī)則。 [5].使用特點(diǎn)，用戶可以在 3D 立體構(gòu)架下設(shè)計(jì)產(chǎn)品。在本文中介紹了應(yīng)用于沖壓工藝規(guī)劃的智能的系統(tǒng)。使用智能理論的沖壓工藝規(guī)劃智能系統(tǒng)被提出來。 2 系統(tǒng)構(gòu)架和框架 智能系統(tǒng)的關(guān)鍵技術(shù)是建立和應(yīng)用的信息化模型制作。智能模型支持表達(dá)和傳遞有用的信息。在這個(gè)構(gòu)架中知識(shí)模型有不同的分類。系數(shù)根據(jù)知識(shí)規(guī)則推理在知識(shí)庫(kù)得出。智能推理的關(guān)鍵是確定基于零件厚度和相關(guān)系數(shù)的加工極限值。 在知識(shí)庫(kù)中有四種排樣類型： ● 一排列布局模式 ● 與一排列相 對(duì) 的模式 ● 兩排列布局模式 ● 與兩排列布局相 對(duì) 的模式 建立 這 個(gè)知 識(shí) 模型的目的是改善材料的利用。 設(shè)計(jì)結(jié) 果包括材料利用率、材料 寬 度和每步 間 隙都被保存在 此模式中，不同布局的 繪圖 也同 時(shí) 生成。圖四說明了此種算法。 。為了解決運(yùn)行程序，該規(guī)則應(yīng)該被制定的合理和有效。確定位置的過程可以和其他元素一起來做，例如：零件形狀、尺寸精度、和用戶要求。輪廓的數(shù)目為 n K = {k1, k2, . . ., ki, . . ., kn} (1) 這里 ki 表示零件的第 i 個(gè)輪廓。如果沖壓點(diǎn)離分餾點(diǎn)太近的話，分餾點(diǎn)就需要被更改到下一階段。這種情況是智能模型中兩個(gè)點(diǎn)的沖突。 對(duì)帶狀布局結(jié)果的處理 帶狀布局的子處理知識(shí)模型中有兩部分：修改結(jié)果和創(chuàng)建布局圖形。 沖壓中心設(shè)計(jì)模型的目的是建立組合力的工作點(diǎn) [11]。圖八 所示為復(fù)合模打孔機(jī)工 作區(qū)域的設(shè)計(jì)結(jié)果。由于復(fù)雜零件沖壓工藝設(shè)計(jì)的復(fù)雜性，開發(fā)一種自動(dòng)生成工藝步驟的系統(tǒng)非常重 要。用戶可以選擇任意一個(gè)作為它們的最終設(shè)計(jì)結(jié)果。為排樣規(guī)劃，更多的設(shè)計(jì)方案的類型應(yīng)該被添加到知識(shí)模型中。t satisfy the users of all the requirements. Depended on the knowledge model data structures, by moving point and change steps, increase steps and deletes empty empty the purpose can be realized step. We can pass the data processing steps to revise the ribbon of the layout design results. Step change can work through exchange of coding to realize two positions, work step increase or decrease can insert or removed by the operation to plete. Code When we want to move some point, we can from the first step to the last step transfer list is points. Figure 7. Shows is the ribbon automatic placement design result [11].

Keywords: arrangement a KBS knowledge model ribbon arrangement method introduction Stamping process planning is one of the core punching product development project. It is the metal molding application an important ponent part of it and the production quality, cost, productivity and tool life have direct influence. The rapid development of modern manufacturing for stamping put forward higher request, especially in stamping process. For many years, the related research has the environment in innovation to strengthen the integration and process planning study intelligentize degree. In recent years, through the production of metal forming intelligent design system, automation technology, the whole and the process planning principles. Intelligent process planning method can effectively improve the design efficiency and quality, innovative design ability. [1]. For cold forging sequence of designing and developing a kind of expert system based on PC, this system based on practical considerations plasticity theory and the rules. At the Ohio state university, a called FORMEX rules system is Altan and his colleagues write multistage cold forging process planning and programming language. [2]. It depends on a cold forging parts of various shapes widely classification. [3] implement knowledge based cold forming sequence design system, adopting the design rule sure to establish a feasible sequence, then using finite element analysis optimization this sequence. A knowledge based mold design automation system is Cheok and his colleagues carefully designed. [4] in the national university of Singapore. Some parts representation techniques
