Description
Technical field
The present invention relates to a kind of information system machining three-dimensional process, particularly machine the construction method of three-dimensional process instruction card.
Background technology
Three-dimensional CAD (ComputerAidedDesign) system has become the basic platform that enterprise digital manufactures and designs at present, realizes product design based on three dimensional CAD system very universal.But current process for machining design is all manually work out based on two dimension drawing, the undue technical merit relying on technologist and experience, design lack of standardization and the establishment cycle is long, two dimension CAPP system is provided solely for the platform of a technics institution, auxiliary process personnel generate two dimension process chart, the Organization And Management of technique is relatively difficult, it is impossible to intuitively, alternatively reflect details and the requirement of the course of processing, understands to downstream personnel and use brings difficulty.
Along with MBD(ModelBasedDefinition, based on model) technology developing rapidly at home, the technological design carrying out three-dimensional environment becomes the study hotspot of current digitized design platform, it is intended to the technological design and the application that utilize three-dimensional means to realize machining, cancel two dimension drawing and process chart, unique foundation with three-dimensional process model for manufacturing, instructs processing.Machining three-dimensional process design can be generally divided into three-dimensional process design, three-dimensional process information management and three-dimensional process scene application three phases.The three-dimensional process design phase mainly includes the steps such as process modeling structure, technique information expression, process structure tree structure, process modeling lightweight issue；Three-dimensional process information management mainly completes the association storage of three-dimensional process data, version management, examines and sign the work such as workflow management, rights management；The application of three-dimensional process scene refers to and is loaded into three-dimensional process instruction card template by calling three-dimensional process data and incidence relation thereof in data base, builds part machining three-dimensional process instruction card, provides three-dimensional for processing site and mach inquires and browses environment.Many scholars have carried out big quantity research for machining three-dimensional process design, but there is no a comparatively ripe machining three-dimensional process design software at present.Given this, to State Intellectual Property Office, applicant has applied for that name is called " construction method of a kind of dynamic 3 D process modeling " and " a kind of technique information expression based on threedimensional model " on June 4th, 2012, solve the problem that process modeling builds and technique information is expressed preferably.
Generation for three-dimensional process file, Chinese invention patent description CN100559375C(realizes method based on the three-dimensional assembly technique file of WEB and on-the-spot teaching, patent No. ZL200810018965.8) disclose a kind of method by Internet/Intranet establishment three-dimensional assembly technique file and assembling animation, it is possible to easily and intuitively the operator of erecting yard are played teaching effect.But, the three-dimensional assembly technique file so obtained, manufacturer can only play the design defined assembling animation of end, can not rotate, convergent-divergent, translation, cannot understand on the whole and hold technical process, simultaneously because the visual angle of assembling animation is fixing, it is impossible to be highlighted region to be assembled, also cannot expressed intact process detail information, it is difficult to reach desirable effect.And after adopting MBD technology, technique information also integrated in the three-dimensional model, technique and in manufacture process different role personnel can pass through MBD model obtain manufacturing information.Current MBD process modeling builds and all generates under CAD environment, while the much information such as integrated size, tolerance, geometric accuracy, surface texture, technique information, it is impossible to be directly used in Instructing manufacture.If machining model is complex, data volume is very big, browses to visual check and brings difficulty.Meanwhile, for shop worker, adopt expensive also without necessity and use complicated original cad tools to browse, it is only necessary to obtaining oneself place operation and machining information involved by each procedure up and down.
Summary of the invention
For overcoming Organization And Management's difficulty of technique under two-dimensional model, cannot intuitively, alternatively reflect the shortcomings such as the details of the course of processing and requirement, it is desirable to provide one can interact operation, directly instruct manufacturer, the construction method of the machining three-dimensional process instruction card readily appreciated and use, quantifies file generated, information storage and technological procedure card including machining D light and generates three steps；Wherein,
