Mould automation technology

1mm, the either side that matchs two curved surface comes demarcate one brim. Although for the angle from pure maths, the precision of this kind of method is inferior to former, but in machining a process actually, this is one more feasible method. Method of model of processing of use public errand is treated the model is being accepted answer in software can work normally, although be in two faces piece an existence very small, unfavorable the gap that perceive. The 3rd phase: Of lifecycle of complete product model is complete product model next. Sometimes the certain part in the model is intended half-baked, that part model of the pattern that products plan division designs an enough to realize design product place to need only and design, and detail modelling part (if the circle pours wine cup) leave mould manufactory the home finish. In car component production, mould manufactory the daily life of a family often gets only face of A of a face (exterior curved surface) model, production him manufacturer of die of hope of spare parts stylist generates inner curved surface (by the wall thick slant buy and into) . Now and then die production manufacturer can get one complete hypostatic model really, although such, also need them to shape model depart core and model antrum two cento face. The product model that even if gets from theoretic say absolutely and complete, die production manufacturer often also needs to undertake to the model a few adjust necessarily, if the change unplugs modular horn, wall is large wait, in order to ensure the spare parts can shape smoothly. Although division of a lot of products plan is now in products plan process,more consideration machines a requirement, machine need in order to make sure a design product can be contented, but there still are a lot of people among them the persist one's old ways in designing a process, make the product of the design is machined very hard. The main problem that die production manufacturer encounters in this phase is: The complex curved surface of a lot of CADCAM systems slants buy function is very poor, because this passes A curved surface,produce B curved surface to may be put in the problem. Most CADCAM system is done not have special model core and model function of depart of antrum curved surface. Depart core and model antrum curved surface is the work with very great strength of a labor. Most system did not unplug technically modular horn and wall are large measure a tool. Most system is additional without special addition unplug modular horn tool (the help takes out a model) . Consider data switch and complete product model at the same time, the mould makes manufacturer need to use technology of curved surface modelling and hypostatic modelling method integratedly normally. A lot of mix system of the CAD that build a model to have this kind of integrated capacity now. The end that uses these two kinds of technologies integratedly depends on can using hypostatic modelling to handle the advantage with standard geometry fast and convenient form already, can use curved surface formative again flexible a future life is become and revise the part with more complex form. For example, a lot of plastic moulds have complex exterior curved surface, and appearance of its interior geometry, if reinforcement or screw protruding stage are opposite simple. For this, can use curved surface modelling to build compose to see curved surface, and use substance model will produce simple inner structure quickly. Same, use hypostatic modelling to be able to produce inner curved surface easily through exterior curved surface. The 4th phase: After model of product of generation mould nap ensures it can have fluent treatment model, mould generation phase is namely below. The generation of the mould involves two step, it is to produce a mould to set firstly piece (composition core and model antrum) ; The other structure that is generation mould secondly (mould bases and other accessory) . The main problem that production manufacturer of this phase die encounters is: Most modelling implement need piece the ground generates spare parts curved surface, next fill clearance, undertake cutting out interactively finally. This is the job of an extraordinary take time. Delcam is to use a mould to set a guide program "DieWizard" to the solution of this problem. This process can search the line distributing a model of product model automatically to distribute module automatically the two shares that are appropriate measure, separate modular side from what change generation high quality, automatic depart core and model antrum. Standard component of need mould spare parts library. System of a little automatic design already owned this kind of standard component library now. More advanced system still allows to use a design to need at the same time any nonstandard spare parts, and in can adding the part after the design ends the user to define standard library oneself, for be being used later. Most mould makes manufacturer hope to build mould structure to design through entity, think hypostatic modelling implement it is to have the CAD tool with this first-rate job. However, of the mould model core, model these partial need use antrum and slide block tool of curved surface modelling is finished. Most die production manufacturer feels current to be returned on the market appropriate without a kind, integrated and hypostatic modelling and advantage of curved surface modelling make can better land their satisfactory tool. Die production manufacturer uses hypostatic model implement the typical problem that structure of the mould that propose form encounters is the curved surface data that inputs with IGES format generation is hypostatic. Bad news of this process or uses time too long; Or may prevent what build compose mould structure through hypostatic modelling completely to undertake. The situation that designs with the model is same, more and more companies get lost now use mix the system that build a model, so that use the most effective means,will complete a design. The 5th phase: After treatment prepares mould hardware design to end, before be being machined formally, still need to undertake a few preparation work. Have the area of cutting treatment to those needing, treatment engineer must choose appropriate treatment cutting tool; The area that cannot undertake to those cutting is machined (be like acerb an internal angle, narrow groove) , need to use electrode to undertake discharging machining to these area. The mould that joins a project through be opposite machines the investigation of manufacturer to discover, this phase basically puts in the following problem: Choose the most appropriate cutting tool very hard to machine area through range estimation judgement. The option of shadow of the smallest radius in using CAD system now undertakes judging wanting to be gotten quickly much, get easily also much. Electrode model devises the main reason that is man-hour incur loss through delay. Typical electrode model is area of spare parts model beg go against, it cuts out next through appearance of geometry of duplicate model area generation. After electrode design ends, need fill to go up advocate the electrode on the model machines area, won't machine discharge area in order to make sure cutting adds man-hour. Need will duplicate curved surface (depict electrode) brim of edge electrode treatment makes drop outspread, cross discharge region certainly with assuring to have, increase it to squeeze next give curved surface to go up and form electrode body. Basically put in the following problem here: The curved surface with first-rate need of body of independent electrode geometry cuts out (normally ground of curved surface of need one by one undertakes) , this needs to be cost for a long time. Generation discharges too outspread face also is the work with very great strength of a labor (get land of surface of one by one to undertake normally) . Need to produce EDM to set detailed account, with fixed position electrode. This job is very as dry as a chip and make mistake easily. Delcam offerred one special electrode to design module PS-Electrode now, it can undertake electrode is designed automatically. Module can identify discharge area automatically, the user needs to fill in in guide program only a few simple table, can finish all electrode to design. The 6th phase: During generation machines cutting tool method to undertake in this project, pass advocate the automation rate of method of cutting tool of cutting of 3D of CAD model generation is quite high already, the problem goes to be machined in 2D. The cutting tool method that people uses alone 2D to machine software package to produce 2D to machine normally (wait for bore) . The most typical is the mould makes manufacturer general data with 2DDXF format (this also is the form of a kind of input that 2D treatment software uses normally) output, weigh a novice to move hole depth of input such as to wait for data next. Apparent, this kind of method makes mistake very easily, also very take time, can say to not was necessary completely. Another problem is must delete 2D feature to offer 3D cutting from inside the model subsequently (lest cutting cutting tool is cut,enter Kong Zhong) . Now, after aperture arises, the treatment information of aperture (so via or blind aperture, it is bore still attacks whorl to wait) can include in the model. These information can be changed automatically by treatment software and generation gives way of wants bore cutting tool. Collateral project ends in products plan normally before, the mould makes manufacturer already began to undertake the mould is designed namely. Be in afore-mentioned in these phase, they can obtain the IGES document of has modified design ceaselessly. Generally speaking, what they get is whole model, is the part that has revised in the model not just. This means them to always lose the certain change of the model in afraid meeting. What just discover a certain place that ignored a model in the later period that the mould is designed and machines is fluctuant, that is deadly. They hope to a kind of method can help the metabolic share that identifies design of the model in giving different version model. Some CAD system already had this kind to be able to be inspected now identify a function. This project built conclusion to be aimed at the CAD software system that the mould makes completely, this system used the mixture of integrated and hypostatic modelling and advantage of curved surface modelling to establish modular method. Outside eliminating all tool that provides place of common CAD system to have, this system still provided the special tool that be designed in the light of the mould in great quantities and makes each level. The 3D model packet that builds through this CAD system contains substantial treatment knowledge, can machine manufacturer to the mould is designed and make a process as the mould advocate CAD model and advocate news source, share for whole company. The model can use Toolmaking-oriented to examine implement (should examine implement to be examined freely implement) examine, can use method of cutting tool of generation 3D cutting and method of 2D bore cutting tool, all setting detailed list of the electrode that generation EDM place uses and need of the place in machining a process. Still need the place of paper head file in those, paper head file can be passed advocate the model is semi-automatic generation, do not have processor of necessary input other (if 2D machines software) . The system that the mould that manufacturing practice joins a project among them as a result made manufacturer do the following description to use project place to develop undertakes mould design is mixed after making, the most immediate effect that we see is whole pattern design and production quality, function and control clear improvement. CAD spare parts and mould precision also have very big rise. We can arise effectively quickly now and analyse the mixed pattern curved surface that comes from different client. In addition, cutting tool method generates ability and method quality to also very old rate rises. The work efficiency of the use efficiency of our CAD system and project technology personnel rises significantly. The system that the another mould that joins a project made manufacturer do the following description to be developed from use project undertakes mould design is mixed after making, we are acceptability the mould of model of more complex form is designed and machine the task, can produce figure extremely complex mould surface and very the cutting tool way with efficient economy. Be less than 8 weeks time, we can be designed and produce the treatment pattern that gives the model with very complex form, and be designed before and machine similar pattern to need 10 to 12 weeks. We distribute a model easily now complex 3D model, effectively generation unplugs modular horn and cent model line. The use that 3 axes 3D machines is gotten simply also much. A variety of new treatment that systematic place provides are politic, great rose to quench the steel, copper, high speed with black lead machines speed. Additional, from movable unripe setting detailed list solved us to felt the most time-consuming in the past, most headaching problem CNC Milling CNC Machining
