Information about the status of all the processing pletely into the inventory management in order to generate a list of sound materials. And then carried out in accordance with the processing line, processing in an orderly manner. The system also provides the operator the daily working hours and machine tool operation processing time data, as well as the work stoppage time to be expected. Sixth of the fast tool servo control Rapid tooling technology is a fast, convenient and practical tool manufacturing technology. This technology is characterized by: a short molding cycle, process simple, easy to promote lowcost tooling, precision and longevity to meet the needs of a particular function, integrated economic good. Especially suitable for trial of new product development, process validation and functional verification, as well as many varieties of small batch production. Due to the increasingly fierce market petition, products, accelerating the pace of replacement, multivariety lowvolume manufacturing will be an important mode of production, in this case, the manufacturing sector to the rapid prototype manufacturing and rapid tooling manufacturer has 常州機電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計正文 第 頁 31made a strong requirements. Therefore, the rapid tooling technology trends vibrantly alive. In recent years, due in the optical and precision engineering system, brittle materials such as glass, ceramic, germanium and zinc sulfide have been caused by the diamond turning of great concern to the people concerned. When the diamond turning of brittle materials, the material may be extended for cutting the state should be maintained in order to avoid damage to the surface material. Brittle materials in general may extend the state of processing can be very low depth of cut and feed rate, but as a result of friction and backlash, especially in the low feed rate, machine coordinates to achieve mmlevel positioning accuracy is very difficult. From static friction to Coulomb friction at very low feed conversion rate of the friction is highly nonlinear, it is difficult to simulate the design. Machine tool to pensate for the friction and the effects of recoil, the design and manufacture of precisionmm three degrees of freedom (DOF) as a quick locator tool servo. This is a standalone positioning device, and the traditional guide rod and the mechanical structure pared to its small, but with high bandwidth and high precision. As a fast tool servo of nanometer Locator feedback 常州機電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計正文 第 頁 32controller and motor drive bined with a high positioning accuracy can be a big trip. Using CMAC neural work control algorithm, available than the standard PID control algorithm and better tracking capabilities and online memory. PC bus through the use of DSPbased on the C language and memory control, to control the diamond turning machine tool and locatornm. 常州機電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計正文 第 頁 33 凸顯成本優(yōu)勢 模具制造新技術(shù) 隨著模具制造的技能化逐步向科學(xué)化發(fā)展，原來依靠主模型和繪制圖形制造汽車覆蓋件模具的傳統(tǒng)方法 ,逐步由 CAD/CAM 終端將由數(shù)字描述的汽車 覆蓋件形狀轉(zhuǎn)為加工軌跡的方法所取代。 排氣系統(tǒng)設(shè)計 在塑料件注塑成型過程中， 當(dāng)塑料熔體充填型腔時，必須排出型腔及澆注系統(tǒng)內(nèi)的空氣 以 及 因 塑料受熱而產(chǎn)生的氣體。 假設(shè)模具平均工作溫度為 50℃，用常溫 20℃的水作為模具冷卻介質(zhì)，其出口溫度為 30℃，產(chǎn)量為（ 1套 /min）即 179。 根據(jù)塑件的形狀特點，模具型腔在動模部分，開模后，塑件留在型芯上。 ? —— 脫模斜度； q—— 大氣壓力 ； ? —— 塑件對鋼的摩擦系數(shù)μ，約為 ～ ； A1 —— 制件垂直于脫模方向的投影面積（ mm2）。其中機械驅(qū)動是利用注塑機的開模運動或頂出作用力，通過哈弗針使其轉(zhuǎn)化為側(cè)向分型或抽芯動作，這種方法在注塑模具中應(yīng)用最廣泛。 注：模具所需開模距離 S S ≥ h 件 +h 澆 +a+(5— 10)mm 式中 h 件 —— 塑料制品高度（ mm） h 澆 —— 澆注系統(tǒng)高度（ mm） h 件 + h 澆 + a+(5— 10) =12+73+50+10=145mm 均滿足要求 （ 3） 模具與注塑機安裝部分相關(guān)尺寸校核 1) 模具閉合尺寸與注塑機模板尺寸和拉桿間距相比較： 模具的座板長179。 4+120179。 45) 179。對于流動性好的 ABS，分流道直徑為 4mm。襯套長度與定模板配合部分的厚度一致。主流道進料口直徑應(yīng)比噴嘴直徑大 ～ 1mm。 根據(jù)以上原則， 結(jié)合 ABS材料的注塑工藝性能，設(shè)計 選用 潛伏澆口澆注 形式，這種澆口的優(yōu)點為：澆口 設(shè)置在分型面上，與流道在同一方向上，且一般在不影常州機電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計正文 第 頁 14響整體外觀的部位，具有進料均勻，不易產(chǎn)生溶接痕排氣條件好。 常州機電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計正文 第 頁 13 確定分型面位置 由于分型面受到塑件在模具中的成型位置、澆注系統(tǒng)設(shè)計、塑件的結(jié)構(gòu)工藝性及精度、模具的制造等因素的影響，因此在選擇分型面時應(yīng)綜合分析比較，選擇分型面時一般應(yīng)遵循以下幾項原則： 1) 分型面應(yīng)選在塑件外形最大輪廓處。飛邊厚度一般應(yīng)小于是 ~。鑒于影響塑件尺寸精度的因素多且復(fù)雜，塑件本身精度也難以達到高精度，為了計算簡便，規(guī)定： a)塑件的公差 塑件的公差規(guī)定按單向極限制，制品外輪廓尺寸公差取負值“ ?? ”，制品叫做腔尺寸公差取正值“ ?? ”，若制品上原有公差的標注方法與上不符，則應(yīng)按以上規(guī)定進行轉(zhuǎn)換。 按照塑料件 2D 圖所示尺寸計算： UG 分析測量 塑件體積 V= 查資料 ABS 塑料的密度 ρ =／ cｍ 3 單件塑件重量 M=ρ V＝ 179。 3) 使用脫模斜度是為了使塑件便于從模具中脫模，但對于高度不大的塑件，可以不取斜度，不會對于塑件有太大的影響，可以忽略不考慮，本制件可以設(shè)置脫模斜度 1176。 在 UG 模具設(shè)計中，利用已有的產(chǎn)品模型，通過建立模具裝
