1．畢業(yè)設(shè)計(jì)的背景：
國(guó)外從上世紀(jì)中后期開(kāi)始利用計(jì)算機(jī)仿真技術(shù)對(duì)顎式破碎機(jī)機(jī)構(gòu)、腔型、產(chǎn)量和磨損等進(jìn)行優(yōu)化，研制開(kāi)發(fā)出無(wú)塞點(diǎn)、高度低、重量輕、產(chǎn)品粒型好、產(chǎn)量高的高性能、低能耗的新型顎式破碎機(jī)，從而大大提高了破碎機(jī)的性能，縮短了產(chǎn)品開(kāi)發(fā)周期，提高了產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力。然而國(guó)內(nèi)對(duì)顎式破碎機(jī)的仿真優(yōu)化設(shè)計(jì)的研究主要限于對(duì)特定型號(hào)的顎式破碎機(jī)編寫(xiě)相應(yīng)程序進(jìn)行優(yōu)化設(shè)計(jì)，這些程序大多重用性差，只能解決特定型號(hào)中的特定問(wèn)題。然而破碎機(jī)的優(yōu)化內(nèi)容是根據(jù)不同客戶(hù)要求需要經(jīng)常變化的，因而仿真優(yōu)化設(shè)計(jì)工作經(jīng)常要重復(fù)大量而繁鎖的編寫(xiě)程序工作，費(fèi)時(shí)費(fèi)力，而且還延長(zhǎng)了產(chǎn)品開(kāi)發(fā)周期。
2．畢業(yè)設(shè)計(jì)(論文)的內(nèi)容和要求：
了解PE400600復(fù)擺顎式破碎機(jī)的工作原理并確定其設(shè)計(jì)方案；進(jìn)行PE400×600復(fù)擺顎式破碎機(jī)動(dòng)顎部分設(shè)計(jì)；主要零件的結(jié)構(gòu)設(shè)計(jì)與強(qiáng)度計(jì)算；用AutoCAD軟件繪制PE400×600復(fù)擺顎式破碎機(jī)零件圖以及裝配總圖，要求視圖完整，其中裝配圖一張，零件圖若干，滿足本科畢業(yè)設(shè)計(jì)要求。參考文獻(xiàn)至少15篇以上，另外有2篇以上外文文獻(xiàn)。完成至少1萬(wàn)5千字的論文，以及至少4000漢字的英文翻譯

1．選題的背景及意義：
我國(guó)自50年代生產(chǎn) 顎式破碎機(jī)以來(lái)，在破碎機(jī)設(shè)計(jì)方面經(jīng)歷了模擬，仿制、圖解法設(shè)計(jì)階段，目前正向計(jì)算機(jī)輔助設(shè)計(jì)階段過(guò)渡。生產(chǎn)制造的顎式破碎機(jī)越來(lái)越大、性能越來(lái)越好，品種越來(lái)越多，并在國(guó)際上占有一定的市場(chǎng)。我國(guó)曾以前蘇聯(lián)顎式破碎標(biāo)準(zhǔn)TOCT7084-80為依據(jù)，制定了顎式破碎機(jī)國(guó)標(biāo)送審稿，對(duì)顎式破碎機(jī)的設(shè)計(jì)、制造和使用提出了更高的要求。
因此全面總結(jié)顎式破碎機(jī)在設(shè)計(jì)、使用和測(cè)試方面的經(jīng)驗(yàn)，積累合適我國(guó)破碎機(jī)結(jié)構(gòu)特點(diǎn)的實(shí)驗(yàn)數(shù)據(jù)和數(shù)據(jù)，建立破碎機(jī)最優(yōu)化設(shè)計(jì)的理論與方法并使之推廣普及是提高我國(guó)顎式破碎機(jī)技術(shù)性能，趕超國(guó)際先進(jìn)水平的關(guān)鍵
2．研究?jī)?nèi)容擬解決的主要問(wèn)題：

（1）研究顎式破碎機(jī)的構(gòu)造。
（2）研究顎式破碎機(jī)動(dòng)顎部分。
（3）研究顎式破碎機(jī)的受力情況。
2.確定主要參數(shù)：（1）.破碎腔的高度 （2）.鉗角（3）.偏心距
3.電動(dòng)機(jī)的選擇: (1).電動(dòng)機(jī)的容量 (2).電動(dòng)機(jī)的型號(hào)
3．研究方法技術(shù)路線：
1． 鄂式破碎機(jī)的總體設(shè)計(jì)方案的擬定；
（1）研究顎式破碎機(jī)的構(gòu)造：確定鄂式破碎機(jī)由動(dòng)顎板、定顎板、偏心軸、機(jī)架和肋板以及一些輔助零件組成。
（2）研究顎式破碎機(jī)動(dòng)顎部分：為減輕重量，采用焊接結(jié)構(gòu)，按結(jié)構(gòu)特點(diǎn)可分為箱型結(jié)構(gòu)和非箱型加筋結(jié)構(gòu)，本次設(shè)計(jì)可采用箱型結(jié)構(gòu)。
（3）研究顎式破碎機(jī)的受力情況：根據(jù)設(shè)計(jì)要求對(duì)其主要零件（如偏向軸、肘板等）進(jìn)行設(shè)計(jì)計(jì)算及強(qiáng)度計(jì)算。
2.確定主要參數(shù)：粉碎腔的高度取決與粉碎比H=(2.25-2.5)B；根據(jù)破碎機(jī)活動(dòng)顎板與固定顎板的夾角可確定鉗角的大小；偏心距大小是由動(dòng)顎行程通過(guò)畫(huà)機(jī)構(gòu)圖來(lái)初步確定。
3.電動(dòng)機(jī)的選擇：應(yīng)用維雅德公式Na=0.0114LDmax可求得電動(dòng)機(jī)容量；首先確定采用三相異步電動(dòng)機(jī)，具體型號(hào)可由額定功率確定。

Differences between hard and soft machining have influences on concept of machines. Stiffness and rigidity are characteristics and variables which caused the precision and quality of machined part.Design/methodology/approach: This paper introduce some of interesting modern machine tools with different concept as DCG (Drive in Centre of Gravity - Mori Seiki), LAF (Look Ahead Function on machine - Sodick), high speed 20.000 60.000 rpm, linear drive, etc. The way from idea to machined part will be shown.Findings: To achieve high precision it is necessary to fill out many request function on machine. Results on machined part depend also from machined material (hardness, structure, size of crystals).Research limitations/implications: Engineers job is to prepare the optimal CNC (PNC) program on connection of CAD CAM softwares. After all mentioned factor test work piece is machined and measured.Originality/value: Comparison between results data on plan and measurement shows us the reality and give us decision around high precision product.Keywords: Manufacturing and processing; Machining; High speed machine tools; Precision machining; Precise products; Soft machining; Hard machining1. Introduction Some specifics of modern machine tool are included over modules, as rotation table, precise high RPM spindle, bar magazine, tools magazine, work pieces magazine, laser zero point measurement system, cutting forces dynamometer for diagnostic of process, frequencies sensor, acoustic sensors, etc., 1. To connect all modules in working action, the machine computer must be excellent. Softwares in computer as NN (Neural Network), GA (Genetic Algorithm), GP (Genetic Programming), LAF (Look Ahead Function), are assuring all time in machining process optimal cutting parameters 2, 3. Many of producers of cutting machine tools all over of the world provide machines in idle level of precision. To achieve precision production we need high level of machine quality. The highest quality caused also high price of machine. Top level ob machine price are 500.000 to 1.000.000 euros for more then three axis machine. 3axis milling machines and turn machines with driven tools are under 400.000 euros. Classical machining on little older machines - no modern high speed, is also very useful in individual production or in tool making industries. The prices of mentioned machines are under 200.000 euros. They are also mostly not able to achieve HS region. HS region is defined with more of elements, which will be shown in some of next chapter of this paper. 3D gravures polishing is very special job for achieving low surface roughness. Its time consumption technology, mostly handy made. That for it has to be automated with driven polishing tool and minimize with choice of special cutting technology. To ensure it is necessary to choice ball nose cutter, low depth of cut, small feed rate and very high speed. After technology are important maters software and controllers, where is include huge knowledge around complex optimization of cutting condition on base of self-learning controller 4,5. Automaticaly federate minimization is very usefull before finishing and polishing closing surfaces by 3D dies and moulds. 1.

Specifics of modern cutting machine tools Mentioned modules are also adaptable. Rotation table is more effective in the case of automated clamping device for work piece.

Below part of figure shows machine cell, powered and control over air and hydraulic medium. Fig.1. Schematically present of medium flow from source to palette on milling machine High productive are turn machines, which are shared in modern classical system on 60 support bed degree as horizontal and new concept of vertical turn machine, Figure 2. With driven tools equipped and both side spindle turn machine is high productive. With added axis as Z1, Z2 and C1, C2 is production 5-7x higher as on conventional lathe 7. Vertical turn machine is also new concept of intensive machining, where the chips have better flow away versus horizontal principle. On Figure 2 is concept with below the spindle with work piece. It is possible also opposite; to be spindle above and the cutting tools are moving over revolver and cascade tool clamping system. Machine like this is more rigid, more precise and high productive.

Robust horizontal machining centre Robust horizontal machining centre, Figure 3 shows rough concept of modules and structure more axis machine. B axis is so called axis nr.4. It gives possibility of complex shapes of 3D work piece. Machine is also more exacting and it is necessary to prepare effective programming engineer of machining. Simple managing from low educated worker gives not optimal machining time and also higher production costs. The latest turn machine bed is under angle 60 degrees. Angle like this on Figure 4, Figure 5 gives optimal solution for assumption of cutting force components 8. The vibrations are limited and chips flow is regulated as well.

KopaVolume 24 Issue 1 September 2007 machining is modern way of cutting with big radius R on cutting edge. Fed rate is huge and remove rate is 8 x bigger. It is very important from view of machining time for achieve required surface roughness, Figure 8. required roughness Rth machining time t Fig. 8. Surface roughness quality versus machining time Cutting tool material has important influence on work piece surface roughness. Especially type of coating as TiN, TiCN, TiAlN caused lower toll wear, Figure 9. As result of minimal toll wear is toll life to achieve criteria of cutting edge changing. Movic as soft cutting caused good sliding phenomena, better tribology contact and better surface roughness. Ra achieved with mentioned tolls is significant lower as by inserts of tungsten carbides. Cutting speed m/min Tool life of cutter m no coating Fig. 9. Tool life of milling cutter carbide cutting tool material with different coatings Ball nose milling cutter is ideal cutting tool for fine machining. Phenomena of that pencil milling tools is possibility to cut work piece hardness to 62 HRc. Producers of cutting tools are able to produce diameter of cuter 0.5 mm with two flutes. Every cutting edge is very sharp and has very precise cutting angles. After machining time the cutting edges are weared, Figure 10. Normal, theoretical wear is on flutes, but middle part of cutter, it means central part can has also some breakages 9. The reason is in smaller cutting speed, where BUE is assist able 10. Tool wear and tool life depends of used cutting tool materials and Nr. of passes of tool over the machined surface. Tool wear W or VB is the best by coating TiAlN/TiN 11, Figure 11. Central wearTool flank wear Fig. 10. Different wear shapes on the pencil milling ball end nose Number of crossingsMedium wear W mm Fig. 11. Toll wear diagram based on middle of cutter After more experiments we carried out optimal solution for precise machining: It is multilayer coatings with last layer of TiN 12, which has very low tribological coefficient. Toll wear is minimal, as shows Figure 12. Normally the parameters of cutting must be defined as a= 0.1mm, f=0.05mm and cutting speed v = 150 - 200 m/ min. By small cutter diameter it is possible to achieve only on HS machine, which has 20.000 to 40.000rpm 13. Fig. 12. Tool wears on cutting edge Figure 13 shows toll wear of the free surface on the rounded tip of the milling tool which is quite big. The break down of the cutting edge is visible on the rounded tip of the milling tool. It is the case of wrong decision of machining parameters. Feed rate in this case was too high. To achieve bigger material remove is not feed rate right solution. It must stay small. Only with higher cutting speed we achieve bigger removal chip volume. Fig. 13.Toll wear on cutting edge by pencil cutter bed case 5. Polishing Last step by finishing of machined surface is polishing. It is useful only in the case, when geometry shape is not request to be in tolerances over 2 m. Polishing is very time consumption and using driven hand polishing tools is request. On this way polishing time is shorter, because vibrant power on polishing segment helped as well. Figure 14 shows last fine machining on closing surface by mould tool. With combination of precise milling, the polishing time was shorted from 16 hours to 3 hours. Fig. 14. Hand polishing of work piece with driving tool Using different diamante polishing gel help also to shorter the polishing time. Different gels are using for different materials. Hardness of polished surface and Ra request different size of diamante cons. Gel fluid and his viscosity is influencing on intensively/time of polishing, Figure 15. Fig. 15. Diamante polishing gel As mentioned above, vibrations powered polishing tools are very effective. Figure 16 shows polishing device with ultrasound powering frequency. It means from 14 to 21 KHz. Movements as this one can be danger for surface in case, when worker is not really concentrated on his obligation. Force on device has to be very gently in another case the surface can be damage over preheating, what caused recrystalization of surface layer. Fig. 16. Hand/driven/polishing of work piece with ultrasound device 6. Case study of precise and ability of machine Sodick Machining case study was carried out over the mould work piece product. Figure 17 shows schematically actions, which are necessary to achieve requested shape of product. As first was done design over one of CAD program. Input of design is new or old part with some changes. In that case RE Reverse Engineering is right way for quick preparing of CNC program. After CAD is CNC program created over CAM software. Missing is still jet post processing, where is for every machine tool controller a little bit another. Case of modern turn machine with integration of many modern modules shows Figure 18. Work pieces magazine is on left and strong control system is on right side of machine centre. Very right is toll magazine. 409Manufacturing and processingHigh precision machining on high speed machines machining is modern way of cutting with big radius R on cutting edge.
