Description
Technical field
The present invention relates to Digitized Manufacturing Technology field, and in particular to a kind of system based on Three Dimensional Design Model
Make operation model creation method.
Background technology
With Three-dimensional CAD Technology application development, Related product is developed and progressively uses MBD technologies,
Achieve significant effect.But compared with external MBD technologies develop, very big gap is still suffered from, its
The application for being mainly manifested in MBD technologies cannot effectively run through the design of product, manufacture overall process.
At present, the domestic three-dimensional digital process design method based on MBD technologies is still in research and visits
Rope stage, the digital process design and product manufacturing pattern with MBD technologies as core is still immature,
The technique department of most manufacturing enterprises is still used three-dimensional MBD model conversations in operation modelling
It is the method for two-dimensional engineering graphic, it is impossible to make full use of existing design three-dimension modeling three-dimensional process mould
Type, manufacturing processes model sets up that efficiency is low, difficult with the management by synchronization for designing a model, it is difficult to effectively
Adaptation design a model change etc. aspect problem.
As shown in figure 1, building manufacturing process's model by designing a model at this stage, mainly reference sets
Meter model, using corresponding CAD software, progressively sets up required manufacturing processes model.Mainly
Construction method have：(1) by part two-dimensional design model retrodict part manufacture process model side
Method.(2) being converted into two-dimentional drawing by part Three Dimensional Design Model carries out creating operation model or directly wound again
The method for building two-dimentional drawing.(3) substance feature of removal material is progressively set up by part Three Dimensional Design Model,
Form three-dimensional manufacturing processes model.(4) Three Dimensional Design Model is relied on, by feature recognition, flexibility
The technological means such as modeling realize the quick establishment of operation model.Above-mentioned prior art is converted in threedimensional model
During for two-dimensional engineering graphic, easily occur data it is inconsistent situations such as.
Three-dimensional operation model can effectively reduce the time of technologist's digestion part model and technical process,
And directly can convert for manufacturing process emulation threedimensional model, but if three-dimensional operation mould is set up by hand
Type, needs substantial amounts of man-machine interaction work, it is difficult to which realization sets up technique mould in Process Planning by operation
Type, practicality is not strong, and is difficult to effectively solve due to the series of processes model caused by design alteration
The problem of the aspects such as change.Therefore, it is work in the urgent need to setting up new manufacturing process's model creation method
Skill designer provides corresponding method for designing and instrument, realizes that the three-dimensional operation model of manufacture is quickly designed,
The frequent change for designing a model is can adapt to, breaks the structure bottleneck of three-dimensional process model.
The content of the invention
It is an object of the invention to provide a kind of model creation side of manufacturing process based on Three Dimensional Design Model
Method, it makes full use of Three Dimensional Design Model, and can effectively adapt to the frequent change for designing a model, and reduces
Technologist's workload.
