【正文】 、復(fù)雜形體工程制圖、工業(yè)設(shè)計高級渲染、塑料模設(shè)計專家系統(tǒng)、復(fù)雜形體 CAM、藝術(shù)造型及雕刻自動編程系統(tǒng)、逆向工程系統(tǒng)及復(fù)雜形體在線測量系統(tǒng)等。集成化程度較高的軟件還包括：Pro/ENGINEER、 UG 和 CATIA 等。另外， Cimatran 公司的 Moldexpert， Delcam 公司的 Psmold 及日立造船的 SpaceE/mold 均是 3D 專業(yè)注塑模設(shè)計軟件，可進行交互式 3D 型腔、型芯設(shè)計、模架配置及典型結(jié)構(gòu)設(shè)計。如 Cimatron 公司的注塑模專家軟件能根據(jù)脫模方向自動產(chǎn)生分型線和分型面，生成與制品相對應(yīng)的型芯和型腔，實現(xiàn)模架零件的全相關(guān)，自動產(chǎn)生材料明細表和供 NC 加工的鉆孔表格，并能進行智能化加工參數(shù)設(shè)定、加工結(jié)果校驗等?，F(xiàn)在精密模具的精度已達 2～ 3μm ，目前國內(nèi)廠家使用較多的有意大利、美國、日本等國的高精度三坐標測 量機，并具有數(shù)字化掃描功能。 霍普森公司 TALYSCAN150 多傳感三維掃描儀分別具有高速化、廉價化和功能復(fù)合化等特點。 高速銑削機床 (HSM) 銑削加工是型腔模具加工的重要手段。意大利 RAMBAUDI 公司的高速銑床，其加工范圍達 2500mm5000mm1800mm ，轉(zhuǎn)速達 20500r/min，切削進給速度達20m/min。 (1)快速原型制造技術(shù) (RPM)。 (3)澆鑄成形制模技術(shù)。 (6)KEVRON 鋼帶沖裁落料制模技術(shù)。如采用氮氣彈簧壓邊、卸料、快速換模技術(shù)、沖壓單元組合技術(shù)、刃口堆焊技術(shù)及實型鑄造沖模刃口鑲塊技術(shù)等。多工位精密沖模常采用鋼結(jié)硬質(zhì)合金及硬質(zhì)合金 YG20 等。另一方面，隨著先進制造技術(shù)的不斷發(fā)展和模具行業(yè)整體水平的提高，在模具行業(yè)出現(xiàn)了一些新的設(shè)計、生產(chǎn)、管理理念與模式。s Psmold and Hitachi Shipbuilding of SpaceE/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian pany Moldflow realistic threedimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software and Zhengzhou University, 6 Zmold software. For manufacturing, knowledgebased intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatron39。s AQ325L, AQ550LLSWEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. Switzerland Chanmier pany NCEDM with PE3 adaptive control, PCE energy control and automatic programming expert systems. Others also used the powder mixed EDM machining technology, microfinishing pulse power and fuzzy control (FC) technologies. (3) highspeed milling machine (HSM) Milling is an important means of cavity mold. The lowtemperature highspeed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (60HRC) and many other advantages. Thus in the mold processing more and more attention. Ruishikelang pany UCP710type fiveaxis machining center, machine tool positioning accuracy up to 8μm, homemade closedloop vector control spindle with a maximum speed 42020r/min. Italy RAMBAUDI39。 Fused Deposition Molding (FDM) and threedimensional printing forming technology (3DP) and so on. (2) the surface forming tooling. It refers to the use of spray, chemical corrosion, electroforming and new method for the formation of the cavity surface and a fine pattern technology. (3) Casting forming tooling. There are bismuth tin alloy tooling, zinc alloy tooling, resin posite forming technology and silicon rubber mold mol
