Therefore, when processing these molds do not need to adjust the mold to the bined conditions, but need to focus on the use of plastic parts of the state of the surface. That is, to use the surface of the shape of the surface accuracy of precision and focus. Five of the management process Application of the system39。s work is usually small calculator and personal puter terminals formed. An effective management system. (Effective Management SystemEMS) software to track the course of processing management. Master processing such as the progress of the circulation status of parts, pieces of the procurement outsourcing situation, receiving and processing quality of the situation. This management system also includes a list of materials, planning and control, inventory management, standard castings, biographical material, with a total production schedules, material requirements plans, orders and sales history, delivery quantity, the operator resume control of the workshop status, schedule, quality assessment, the standard processing line, capacity requirements plan, labor costs, outsourcing plans and delivery status, requisitions, purchase pieces of history and the number of deliverables. Application of the software you can 常州機(jī)電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì)正文 第 頁(yè) 30select the appropriate items purchased to save time and labor. 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(jī)電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì)正文 第 頁(yè) 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(jī)電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì)正文 第 頁(yè) 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(jī)電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì)正文 第 頁(yè) 33 凸顯成本優(yōu)勢(shì) 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(lái)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。用電話線路遙控加工過(guò)程則又將模具制 造科學(xué)化的水平推向一個(gè)新高度。 回顧以前，在加工用具有于沖制汽車外覆件的鋼制模具時(shí)，必須繪制詳盡的藍(lán)圖和具有按照沖件精確尺寸制造的主模型。可以說(shuō)，模型是設(shè)計(jì)和制迼模具的母型。 一、在用鑄造方法制造模具時(shí)，首先必須置備木?；蚱嚵慵臉蛹凑找欢ū壤瞥傻哪Ｐ头Q之為靠模，常被用作仿形加工中的母型，或作為顯示銑床加工軌跡的輔助模型。作形銑床上的靠模指沿靠模輪廓形狀移動(dòng)，銑刀則按照靠模指的移動(dòng)對(duì)模具材料進(jìn)行銑削加工，仿出所需的模具型腔?，F(xiàn) 在的加工方法則發(fā)生了根本的變化。由客戶所提供的 CAD 數(shù)據(jù)生成銑刀的切削加工軌跡，自動(dòng)加工出汽車覆蓋件的沖壓模具和進(jìn)行 塑料 板材 模壓成形的型腔模具。 雖然用這種新工藝能比以往加工方法更精確地加工出模具的兩對(duì)合面，但對(duì)于壓形還要進(jìn)行試模，并對(duì)試樣進(jìn)行測(cè)量。通常由 CAD數(shù)據(jù)正確地加工出模具的主要型腔表面，然后由防止磨損墊塊和其它零件與主要型腔面相配合?，F(xiàn)在可將這種新技術(shù)的特征歸納為以下幾個(gè)方面。 常州機(jī)電職業(yè)技術(shù)學(xué)院 畢業(yè)設(shè)計(jì)正文 第 頁(yè) 34二、不需要主模型和靠模雖然不再使用主模型和靠模，但加 工
