The society deploys motive force for automation CAM system, not only be helpful for business development, and the treatment that can think reserve is the most outstanding in the future carries out knowledge. Carry out a proof, offer operating system of automation of pushbutton type CAM to be able to tell an engineer how to weave their part program. This is means of another kind of thinking, in automation CAM system, process designing member issue a statement to the system, how to undertake machining to the spare parts. So is this kind of means how popular those who rise? Perhaps be in CAM software development business tries to help the automation technology with user new application, install the treatment parameter of industrial standard what begin until this system is medium beforehand. We know the engineer has the idea of themselves to this thing, because this should make all " standard " making each person satisfactory is impossible. The acquiescent cost that holds beforehand can regard example as directive user only, but the proposal that they often are understood to become dealer. In other words, it already made a system that can help understanding of process designing personnel how should work. Want to list a few specific example to explain now, how to establish system of an automation CAM, so that accelerate working schedule, make the job more easy. System of pushbutton type automation above all, alleged " pushbutton is changed " the operation is meant need to press only use button a few times, CAM user can begin to undertake one or more automation processes an operation. The button that makes place of code of NC numerical control need is pressed move a frequency to depend on why is company decision planted in the installation in the system automation system. Anyhow, still need to a certain quantity of user acts, directive CAM system carries out wants job. Generally speaking, in the begining, the user is started only carry out an automation task or two simple tasks, when they are more skilled, increase again execute more automation missions. Press every time use button, the system can be in a few seconds in execute a mission; If collect labour of choose and employ persons to execute this mission, the time that needs a few minutes commonly. But systematic itself can not give him make known to lower levels and affirmatory job. Only the possessory ability of CAM software issues a series of statements to the system, coach how its apply. The fundamental job of the fundamental automation of automation begins from the database, how do all sorts of production conditions that store inside the database above all and organize job shops and company process the concerned information of its spare parts. The goal that establishs a database is to there is machine tool of CNC numerical control to wait for concerned data inside effectively duplicate and all cutting tool, raw material and workshop. And more important is, the database can store the treatment parameter through carrying out test and treatment craft, such, when establishing a program, CAM system can make best choice. The database that place of some CAM system offers contains the data that assembles beforehand. If had assembled such data beforehand really, should have a look so, whether are these data close to the actual condition of job shops. Use these data to be able to edit the program of form a complete set that establishs to be cut truly easily. All other data can be abandoned need not. Delete the data that everything and job shops have nothing to do, can understand next how to machine a spare parts. Otherwise, this system can choose a kind of cutting tool that does not match with workshop work requirement and cutting treatment strategy blindly. A lot of users are willing to delete these data not quite, but still can install CD through CD actually, reinstall former data. Automation CAM system also can store all sorts of treatment reference standard that operate a type. Let an user at this o'clock experience real value through automation system just about. E.g. , if a job shops always is the data with hard temper by dipping in water of treatment of the cutting on the machine tool in its top speed, can machine the task specificly to store for this so an appropriative machines parameter. Perhaps can install a few different treatment parameter respectively, in order to satisfy the requirement of different client. If of the treatment inside the workshop is to become the part of the group, can store so the referenced treatment data related to each series part. Anyhow, the database can expand, can store almost the grouped data of any workshops and treatment parameter. Once input data the system later, can let everybody share, and process designing personnel can use these data instantly. After be being opened when the file of a spare parts, first job is to tell this system concerned job, need the data of treatment for example, the spare parts type that chooses what treatment parameter and need treatment. All these will provide enough information to the system, so that accurate data is searched in the database, when undertaking operating next, input treatment parameter automatically. The simple task that installs concerned workshop data in the database can allow CAM system: (1) the material according to the spare parts and operation type, choose correct cutting tool automatically. (2) the circumstance according to machine tool of deepness of hardware data, cutting tool material, cutting and NC numerical control, calculate automatically reasonable main shaft rotate speed and feed speed. (3) the treatment parameter that automatic choice user defines oneself. Another respect of system of automation of type of pushbutton of characteristic automation system is versed in in Yukejia characteristic application. The hypostatic model in CAD/CAM system is made according to the character of a series of mutual connection. In system of a CAM, the characteristic faculty that depicts a model can expand further, include to process information among them, it will make spare parts model impartible a cut share. Adopt this kind of method, treatment data will be updated automatically while the model is updated. Major CAM system includes milling fabricating characteristics of the standard, for example stage of hole, aperture, grooving, protruding and groove, plus special turning fabricating characteristics and fabricating characteristics of EDM line cut. After allowing an user to a kind standard character makes a definition and turn its user to hole when the system, when making its turn industry into peculiar character, for example flow path and runner, use the treatment technology of its itself, in order to get used to this kind of characteristic form, this is the true advantage that it has. Next, CAM system can identify the flow path on spare parts model automatically, know how to machine this spare parts according to the requirement of the company. The characteristic that the graph can machine each times when 1 automatic character identifies a system to be able to identify spare parts model to go up automatically, a crucial essential factor that cavity of the aperture that includes this model to go up, open mode and groove Nextpage identify character automatically is automation system. It is a the most perfect example to the identifying of bore diameter among them (graph 1, 2) . CAM system can identify the aperture in CAD model faultlessly. Below this kind of circumstance, want to click each aperture in can discerning hypostatic model only. Because fabricating characteristics is included in the character of CAM system, the type because of these each aperture, dimension, deepness, pour horn or heavy Kong Dou to be able to identify easily. The working plane of each aperture also is included in each character, getting in cutting treatment, this kind of character is very crucial to determining the direction of the spare parts. The aperture with same size can induce together in group, with reducing cutting tool change frequency, all aperture can be contacted together, undertake deciding nodding getting cutting machining above all, bigger to the diameter and cannot get cut aperture, can use the method that milling machines. Using full automatic after changing a system, can pass character identifying, make each drilling operation is carried out according to first-rate order, need not intervene artificially. The graph should click all aperture that can identify spare parts model to go up 2 times. The character of every aperture also needs to analyse and be saved, in order to achieve the goal of automation bore to enhance the characteristic of automation system further, should allow this system: (1) can identify automatically and get cut treatment (or milling is machined) all sorts of aperture. (2) can identify automatically and machine a standard with appropriative character workpiece. Enclothe a mouth automatically to although automation is not,be in concern with all data and character. A lot of CAM systems go to complex automation function confluence in software, in order to analyses the geometrical form of the spare parts. To die manufacturer, this are particularly important, because the mould is,comprise by the mixture body of complex surface and the standard part that must use different technique to machine. Plus the geometrical figure with original basis, a series of move such as 2 the rough machining that uses all sorts of differring commonly, rough machining and finish machining will complete the treatment of whole face. Cast off these ties to help process designing staff, automation CAM system can change means to cover the mouth part on spare parts model with intelligence, such cutting tool can be machined on the spare parts automatically, like be like these mouths to exist far from (graph 3, 4) . Can machine the surface in order to prevent in milling so while, cutting tool accident cuts mouth part, produce risk. This system can analyse a model before method of computational cutting tool, generate overburden automatically. When treatment handles an end, this overburden can be eliminated automatically, or store rise when after regarding as, other treatment is operated, use. This is helpful for process designing personnel casting off dull manual work, do not need to be what machine in process later to enclothe an area to found useless surface. Enclothe any apparently aperture automatically, include to contain the bend inclined hole of proper point of view; Cover the mouth part on complex form face automatically. Graph 3 before generating cutting tool to machine method, CAM system can cover the aperture of spare parts model and other mouth part automatically. After in cutting tool treatment method is finished, this system still can cancel this kind to mask automatically. The deepness that covers an area is complete by the user in each pace rough machining, semifinishing machining and finish machining process undertake dominating a picture 4 mask a mouth automatically when CAM system when place, when masking these aperture that in resembling a plan, show for example, having a bit is very important, namely conform to of shape of as should whole as what machine the surface bodily form combines new face, no matter how its form is complex,system of CAM of automation of rough machining of Nextpage high speed uses advanced computational method and according to cutting tool constant bear, the appearance of method of computational cutting tool, always workshop can the place of managing and many handling time, can use CAM system to undertake rough machining works. Specialization rough machining operation can make whole cutting process generates a negative charge that cut bits even, because this needs to consider two factors: (1) the appearance of spare parts geometry of deepness of each increment class; (2) when any specific places in be in cutting tool method, the contact between cutting tool and material is measured. Graph rough machining of 5 high speed walks along cutter track diameter to begin from helix motion, can be in the biggest can move inside treatment computation limits every time when cutting tool and material are contacted in the round, the system can adjust automatically the appearance of cutting tool method and feed rate. Because the pressure on cutting tool is quite low, because this is below rotate speed of extremely high feed rate, main shaft and cutting deepness condition, cutting tool still job of can flowing, glibly moves (graph 5) . Its characteristic is: (1) use adaptability rough machining to walk along a knife to be able to make the appearance photograph be identical of its and spare parts, produce relatively good surface quality. (2) fall in condition of constant the bear that cut bits, can raise the rate of spare parts rough machining. (3) the pressure that prevents to produce excessive on cutting tool, lest cause cutting tool by the circumstance of bite into. (4) use form type and method of screw type cutting tool. Method of axial cutting tool changes a plan automatically 6 although use treatment of cutting of method of high speed cutting tool to need to spend longer time it seems that, but the way of cutting tool treatment that actually it wants to compare a tradition is gotten quickly much, because constant cutting bear can make cutting tool increases span and cutting deepness to be machined to satisfy strong voice milling,apply the need of the domain, a lot of companies use shorter cutting tool to undertake machining, in order to raise the tigidity of cutting tool (graph 6) . But the problem is, when the 3 axes milling that uses a level is machined, these cutting tool cannot be achieved model in antrum. CAM company is determined to solve this problem, allow an user to use strategy of 3 axes milling, as far as possible cutting more cutting tool method. On 3 axes method, when software feels cutting tool or knife clip collides, can make path of this cutting tool separate automatically, change its way of 5 axes cutting tool, reduce cutting tool as far as possible tilt, with time of managing fixed position. Its characteristic is: (1) use shorter with the cutting tool with use tigidity better. (2) the 3 axes in same unit process of cargo bandling and undertake intelligence changes changeover between 5 axes. The reserve that machines knowledge makes a worker leave this field as seasoned mould, and the new worker that enters this industry very few, because this is attracted,having technology and knowledgeable worker is very important, having crucial effect to the development of business. The company needs to invest a lot of capital, ability education goes an outstanding mould make a worker. These charge include to go up hardware of machine operation, computer, software and technology of tool clamping apparatus, wait plus salary, welfare, public facilities, insurance and other charge. Intellectual total contain is in the worker's brains, is not to be inside the company, when because this is become,employee leaves because of retire or finding another job, the old painstaking care that he took away a flower to go up in his body and charge, incorporate the knowledge that he acquires. Create knowledge to withhold the most outstanding mould, the company must find a kind to be able to attract talent and the method that lay in knowledge, make other moulds make industry support of the people groom personnel can use these knowledge. The manufacturing technical data that automation CAM system can let a company optimize the course for years stocks the computer inside, the member that allow company someone else is close to and access these information, let they are shared and use these knowledge. Use CAM system to store knowledge, let the computer duplicate executive job, encourage the staff member expenditure with outstanding technology to more time are transformed and raise craft level. Complex CAM automation system can make pattern production company uses this kind of politic dominant position, deploy its talent resource better, increase the competitive capacity of integral business.
