(3) digital control processing under the networked manufacturing mode
A) requirement to digital-control processing system is made in networking
Networking manufacturing is a kind of brand-new manufacturing mode, turns to essential characteristic with digitizing, flexibility, agility.Under the network environment, digital control system is as a branch of networked mfg system, and also should satisfying requirement that networking makes on structural system and functional requirement, to make manufacturing equipment no longer be information island.Therefore as the digital control system of visual plant resource in the manufacturing system, an urgent demand has network function.
Digital control system experienced from hardware numerical control, closed computer numerical control stages such as open cnc till now, but the network communicating function of digital control system is also very weak at present.Though many digital control systems have possessed certain network savvy, what mostly adopt is primary and secondary structure, and following 3 kinds of modes are adopted in message exchange basically: 1. select the DNC network interface software that meets the MAY standard for use; 2. link to each other with network by the YC machine; 3. finish functions such as transmission of NC program and conditions of machine tool data acquisition by " DNC device " or " numerically-controlled machine integrator ".This digital control system itself does not have network function, can only realize the transmission of partial information, and can not realize resource sharing.
B) gordian technique of networked digital control processing
The gordian technique of networking digital control processing has a lot, and major technique has: the foundation of the two-dimentional visual environment of distributed collaborative design; The Web publishing of product figure and simulation result with browse; The Network Transmission of numerical control code; The technological parameter network optimization and transmission; Strange land process monitoring model; Revise in the strange land of product model data; Strange land design and the product model data management system of making; Safety precaution mechanism; Instant communication-online communation mechanism spanning space-time.To promote the development of networked digital control processing for above every Study on Technology comprehensively.
The numerically-controlled machine processing parts is controlled by the numerical control instruction repertorie and is finished.For guaranteeing the correctness of numerical control program, prevent from the process to interfere and the generation of collision, in actual production, often adopt the method for trial cut to test.The expense material costs dearly but this method is taken a lot of work, and production cost is risen.For this reason, people are studying the computer emulation method that can progressively replace trial cut always, and having obtained important progress at aspects such as simulation calculation and graphic presentations, the forward directions such as the sense of reality that improve degree of accuracy, the simulation calculation real time implementation of model and improve graphic presentation develop at present.
NC working angles emulation at present divides geometric simulation and two aspects of mechanics emulation.Geometric simulation is not considered the influence of cutting parameter, cutting force and other physical factor, only considers the motion of emulation cutter, workpiece solid, with checking NC program correctness.It can reduce or eliminate problems such as the lathe damage, the anchor clamps that cause because of program error destroy or cutter fractures, part is scrapped, and can reduce simultaneously from product design to the time of making, and reduces production costs.The mechanics emulation of working angles belongs to the physical simulation category, and it predicts tool failure, vibration cutting, control cutting parameter by the dynamic characteristics of emulation working angles, thereby reaches the purpose of optimizing working angles.
The development of geometric simulation technology comprises qualitative graphic presentation and quantitatively interferes checking two aspects along with the development of geometrical Modeling Technology develops.Method commonly used at present has direct solid modelling method, asks the friendship method based on the method and the dispersion vector of image space.
Direct solid modelling method: be typically and utilize constructive solid geometry MODEL C SG or border expression B-Rep solid modelling system to realize.These solid modelling systems have the ability of good boolean set computing, and accurate NC emulation and checking can be provided theoretically.But directly the solid modelling method relates to a large amount of directly Boolean subtraction calculation in proof procedure, makes the checkability of these class methods lower.
Based on the pattern space method: realize the NC checking by the set that the entity geometric model is decomposed into some three-dimensional bodies.Dexel representation wherein by set up one independently the Dexel coordinate system support dynamic vision conversion, its structure no longer is subjected to the restriction of direction of observation; It is simple that the quaternary tree of stratification is expressed Boolean calculation, and the stratification tissue of data helps the processing of NC checking.But the demand to internal memory is bigger, can not directly apply to the NC checking; The Voxel modeling makes the Boolean calculation amount drop to the limit, but needs high-grade graphics workstation as hardware supported.Adaptive control technology can be according to the actual conditions of process corresponding adjustment and optimize cutting parameter, shorten process time, reduce production costs, monitor in real time, but in complex-curved Milling Process, during the contact relation more complicated of cutter and workpiece, can't in time adjust, be difficult to satisfy the requirement of complex-curved numerical control milling processing feed rate.
Dispersion vector asks this method of friendship method that curved surface is discrete by certain precision, represents this curved surface with these discrete points.Vow to be the direction vector of this point with the method for each discrete point, prolong with the outside surface of workpiece crossing.By the working angles of emulation cutter, calculate each discrete point along method vow cutter apart from s.Adopt the method for image mapped to show the mismachining tolerance figure; The mismachining tolerance of piece surface can accurately be described out.
On the whole, consistent with actual process based on the expression of geometric model in the method for solid modelling, making accurately relatively becomes possibility between the net result of emulation and deisgn product; But the technical requirement height of solid modelling, calculated amount is big, and difficulty is applied to detect in real time and dynamic similation under the practical environment of present computing machine.Method speed based on image space is faster, can realize real-time simulation, but because raw data all has been converted into pixel value, is difficult for detecting accurately.Dispersion vector is asked the surface treatment of friendship method based on part, can accurately describe the mismachining tolerance of part surface, is mainly used in the error-detecting of Machining of Curved Surface.
(1) domestic and international research present situation
For improving the working (machining) efficiency of mould, the new method that K.Yamazaki has proposed a kind of " Real Time Model ReferenceAdaptivecontrol ".This method is adjusted feed rate automatically according to cutter load capacity and workpiece geometries, makes the removal of material remain on maximum rating as far as possible.K.Weinert has set up the relation between smear metal cross section and the feed rate by the analysis to workpiece and cutter contact conditions, has wherein considered the influence to feed rate optimization result of machining direction and Machine Tool Dynamics characteristic.M.D.Tsai adopts expansion Z-buffer Geometric Modeling Method on the Sun4 workstation. developed the cutting forecast system.The physical verification of working angles also relates to the monitoring of tool failure.Though with identical based on the online detection monitoring of the tool failure of hardware, the variation of matter has taken place on concrete implementation: the monitoring basis is transformed to software by hardware, and monitor mode is transformed to forecasting mode by on-line monitoring on principle.
The research that China carries out numerical control program emulation starts from late 1980s.Even but by the machining process simulating device MPS of HUST and Tsing-Hua University's cooperation research and development, and the digital control processing process Three-Dimensional Dynamic graphical simulation device NCMPS that under the support of the scientific research project flexible manufacturing system FMS of Commission of Science, Technology and Industry for National Defence " eight or five " gordian technique project, develops by Harbin Institute of Technology, also exist the ability that does not possess accuracy test, and all with the workstation be hardware foundation.The needed expensive hardware investment limitation of limitation on this function and operating software applying of software systems.In order to address the above problem, professor Liu Huaming of Harbin Institute of Technology leads seminar to develop the complex-curved nc machining simulation verifying software bag of a cover based on microcomputer.The three-dimensional model of this system does not adopt CSG and B-Rep to express, but on the basis of own exclusive complex-curved discrete technology, make up.The advantage of this curved surface discrete technology shows: greatly reduced the requirement of simulation checking system to hardware, even in NC program verification process, the user also can choose at random arbitrarily angled observation process, this is inconceivable for the simulation checking system based on solid modelling, and the machining precision checking can be achieved with a kind of simple more method.The exploitation of this system is based on the COM technology in addition, and every function of system all exists with the form of assembly (COMPONENT), makes system be more convenient for safeguarding and upgrading.
(2) Web publishing of simulation figure with browse
Also many about the research of simulation figure Web publishing and browsing mode at present, conclude and get up to have three kinds of modes: animation data, the transmission standard formatted file of downloading process avi file, transmission process.
For the avi file of first kind of figure issue mechanism download process, the digital control processing 3D geometric simulation network structure based on isomorphism, isomerous environment of Northeastern University's research is exactly this mode that adopts.They are divided into three grades of transmission mechanisms of G/C/B with this network structure: produce layer (Gerneration Layer) and convert digital control processing 3D geometric simulation vector graphics to bitmap animation that Web supports, finish storage with the AVI form, form the animation broadcast format of each operating system and Web browser acquiescence; Articulamentum (Connection Layer) is used for the nc machining simulation figure end that uploads onto the server; Browsing layer (BrowseLayer) is interactive dialogue process between user and the home server.The nc machining simulation figure uploads to home server, through after the Data Update, downloads to client.
The Central China University of Science and Technology and NUS unite proposition " Multi-UserNC Machining Simulationover the WWW " scheme, and the RTSSW of simulation software that University Of Tianjin develops all is the second kind of mechanism that adopts.This scheme is placed on the server end operation to the emulation prototype system, and animation that it produced or video data transfer to by Socket in the three-dimensional visible environment of client, and therefore the user can browse to the real-time information of process.This figure issue mechanism has been obtained interactivity preferably between the server and client side, be easy to set up the stronger machining simulation process of collaborative.But its shortcoming is also comparatively outstanding, carries out the operating load that has strengthened server at the emulation kernel program of server end, and the transmission of animation data is also higher to the requirement of network technology condition.
The numerical control milling analogue system based on web of the Qin Xu of Nanjing Aero-Space University research has adopted the third scheme: the strange land processing of emulation prototype system.Avoid the Network Transmission of animation or video data, improved the execution efficient of total system.The emulator of development can read in the NC program code, carries out nc machining simulation and show the program of three-dimensional picture information.This program has successfully realized modularization, for user's download.The process of machining simulation both can be carried out at server end, can carry out in client again, and both can obtain different machining simulation effects; The video data that emulation obtains is no longer by Network Transmission, but the emulator assembly that adopted more efficiently mode-Ruo client downloads after the process data of input standard format, directly carries out machining simulation in this locality; If the client needs server end that the service of " systematization " is provided more, then whole process can be given fully the server end operation, treat server end after having uploaded the avi file that comprises the machining simulation process on the website, directly download gets final product.
The common structure of distribution application system generally has two kinds: the two-layer structure of C/S (Client/Server), B/S (Browser/Server) three-decker.The C/S structure is divided into client-server with the computing machine of application system, and the function of system is divided between client-server.The system that this structure is formed is the system of a relative closure, and it makes between the different system and can't exchange; Its user-interface styles differs, and is unfavorable for promoting the use of; System development and maintenance are complicated, transplant difficulty, and upgrading bothers; Can't contain existed system, cause overlapping investment; Can not admit new technology, limit extendability; Lack systematicness and perspective.
