Machining center and flexible the line is to be used at much breed to machine. Its characteristic is spare parts breed change of much, working procedure is big, the workload that plan designs is gotten greatly than common modular machine tool much. Use traditional artificial design method, want to spend much labor power and time, often finish hard inside the time of the requirement. If introduce CAD technology, produce its specialty, the effect is very distinct. In this respect, we made a few works and undertook abecedarian application tries. Above all, according to real need, baconian arranged a few machining center and flexible the commonly used machine tool in line plan design, cutting tool, tool, splint, car having course, car that do not have course, raceway, cleaning machine and cutting dosage relevant data and graph, built graph library of the part, database and mathematical model. On this foundation, we made these gain abecedarian application attempt, obtained very good result. Lift two example introductions to be as follows now: Exemple 1: What I am saddle hill to heated up project instrument and meter plant to offer K6307 of a machining center, use at processing system of 49 kinds of different a powerful person. Body of these a powerful person have 7 kinds to open way differently, 4 kinds of different pressure, dimension change is bigger. A diameter of body of 49 kinds of a powerful person and pressure see a table 1. The machine tool machines body of which kinds of a powerful person to depend on completely order goods, because this is manufacturing the variety in the process,change very frequent. Sometimes of a kind of a powerful person order goods the quantity has a few only, and changing to need to change when breed or adjust clamping apparatus, cutting tool, program to wait every time, sketch map of their process chart, treatment, clamping apparatus adjusts a graph to wait must complete, clear, ability assures to operate personnel have the job smoothly. Because have 49 kinds of different parts, design workload is very big. We introduced CAD technology, make all sorts of module first by real need, the clamping apparatus that draws need of all sorts of spare parts place again adjusts graph and treatment sketch map. Needs time shortens greatly, and the quality of the graph rises greatly however. The workpiece process chart that draws all sorts of parts (graph 1) pursues 1 workpiece process chart draws a clamping apparatus to adjust a figure (graph 2) pursues the clamping apparatus that 2 clamping apparatus adjusted graph this chart to show the place when machining JP40-50 of body of a powerful person to choose is 21 groups of clamping apparatus. Two parts can be held on every clamping apparatus. The adjustment of place make choice of is filled up for 2146(block up 32.

392) , form piece adjusts the V that locates two end to leave clamping apparatus side 66.

5 place. These 21 groups of clamping apparatus can be used at opening way 40 with the body of 3 a powerful person of 50 (in all 8 kinds of) . This graph still showed the CNC when processing form of this a powerful person to answer the part program date of v is 3-50-40. Operation personnel will choose by this graph and adjust clamping apparatus. If change breed, need to change only adjust mat, the form piece distance to the side of clamping apparatus can realize the V that changes fixed position. The picture gives treatment sketch map the 4th foreword pours wine cup (3) seeing a picture. Graph 3 the 4th foreword pours horn to machine the place in sketch map graph to show one of be 49 kinds of spare partses (body of a powerful person JP40-50) , the body of 3 a powerful person of 50 diameter, pressure is 4MPa, the circle outside using 3 flange locates, place of wide solid line shows the face that machines for the requirement and hole in the graph, made clear the measure that wants treatment and public errand. What this foreword uses is special knife pouring wine cup, the position of its knife head is adjustable the amount is very large. The dimension v that can press treatment sketch map to indicate when processing system of all sorts of different a powerful person (the dimension) that dimension and point of a knife extend to reach arbor center outside including point of a knife to carry. Because this knife is used for a lot of spare partses, so the worker will move a knife by this dimension. Whorl of mill of the 7th foreword pursues mill of 4 the 7th foreword thread machining sketch map to big whorl, use whorl to comb the knife is machined normally on FMC, if the graph is shown 4 times, the combs the knife passes planetary mill method that uses a F30 is OK the whorl that mill gives all sorts of different diameters (M64 × is in the graph 1.

5) , the contrail that center of its cutting tool walks along is like place of the Zun Tu in the graph to show, divide 1 ～ 5 paragraphs. The first paragraph of cutting tool from aperture center transverse feed arrives R30.

688 place, inside 90 ° area feed arrives the 2nd paragraph R32.

212 place, had finished cutting tool right now cut, the 3rd paragraph finishs planetary mill a week inside the limits of 360 ° , the 4th, 5 paragraphs to exit. Because whorl combs the knife is a kind of new-style cutting tool, to facilitate operation personnel and spot technology personnel understand a process, so the picture gives the circular chart of this knife. Because every kinds of spare parts has 4 kinds of different stuff such as cast-iron, cast steel, stainless steel, place has a few kinds of different cutting dosage with be being filled in the graph. Above blueprint designed 49 in all, every kinds of spare parts, every cover ten pieces, in all more than pieces 700, be operated personnel by user factory reputably. If use traditional method to design, need is severalfold even the time ability of ten times is finished, the quality of blueprint is opposite also poorer. Exemple 2: What for heavy Qing Mou the factory designs is flexible product line plan. This factory asks to use flexible the transmission housing that product line treatment differs 6 kinds. This product line needs to use 14 vertical machining center and composition of 2 horizontal machining center. Because attend,those who bid is foreign manufacturer mostly, the user is taller to the program requirement of mark book, demand picture gives the every kinds of every machine tool, spare parts, program that installs every time to pursue (see a picture 5 ～ 7) . Graph 5 plan machine sketch map with transmission housing 1 graph 6 plan machine sketch map with transmission housing 2 graphs 5 reach the graph is shown 6 times plant for some the sketch map that the spare parts machines on some machining center. Method of the position that this graph represented to be machined on this machine tool, dimension and precision, location and chosen cutting tool are waited a moment. Flexible to this 16 machine tools in the line, 6 kinds of reducer, such graph needs 100 pieces or so (some working procedure are longer, a piece of drawing does not fall, pursue for example 5) . The cutting parameter that shows cutting tool to the place in the graph needs another piece of form to express. Pursue for example 5 parameter that show treatment content are in watch 2 in give out. Graph 7 transmission housing is flexible product line expresses computation of 2 handling time to express installation number serial number to machine time of cutting of V(m/min)s(mm/r) of content cutting tool (S) first time is installed (treatment bedding face) milling cutter of face of F80 of 1 mill bedding face 6000.

5 the time of project invite public bidding is normally average very short, such many blueprint is being made in the method that labour servantchooses a person for a job in short time is impossible. And the plan that we make with CAD is in numerous bid the be among the best of candidates in the unit, and reach as same as foreign manufacturer level. We made the FMS plan with overall housing of reducer of a treatment for some car plant again recently, also get of user factory reputably. We work in what this field place does, it is a kind of abecedarian application only, major material, data and experience are accumulate in real work those who rise, fundamental job also has stage by stage in applying actually, further after application still remains to work in great quantities at doing, ability comes true. For this we should perfect library of all sorts of databases, graph, enrich fundamental part, develop all sorts of management software, call all sorts of module according to different need, raise the automation rate of the design. Its target wants to use CAD technology adequately namely, accelerate design rate, improve design quality, enhance competitive ability, can make we stand firm in this domain thereby, remain invincible.
