Casting three-dimensional process designing method

Abstract

The invention relates to a casting three-dimensional process designing method which solves the problems caused when the two-dimensional mode is adopted for the existing casting process. Firstly, a casting three-dimensional process designing system which can have the three-dimensional manufacturing reception capacity is designed and is then integrated with a CAD modeling system and a process simulation analysis system; in a system formed through integration, three-dimensional design data issued by a design department are firstly received from a design data management system, compiling is conducted on the basis of the design data, a casting blank model is generated, an appropriate rigging system is selected from a rigging system library for assembling, a rigging system is recreated and kept into a knowledge base if no appropriate rigging system exists, manufacturing parameters, manufacturing process resources and the like are designed, simulation analysis is started on a simulation interface under the analogue simulation conditions, the simulation result is analyzed, the process and manufacturing parameters are optimized, the process is determined, and a visual three-dimensional process is formed. By means of the casting three-dimensional process designing method, the process design efficiency is improved, and the cycle of process development is shortened.

Description

technical field [0001] The invention relates to a casting three-dimensional process design method. Background technique [0002] At present, the casting process design adopts the two-dimensional mode, and the process design is completely dependent on the paper two-dimensional drawing that uniquely expresses the design intention. Due to the limitation of its expressive force, it is wasted in the mutual conversion between the physical image and the abstract two-dimensional view expression. With a lot of energy from craftsmen, ambiguity and deviation inevitably arise. The formed process lacks verification, and the problems that cannot be exposed in the process design process are moved to the manufacturing process. The following specific problems exist in this process design method: [0003] 1. At present, domestic and foreign countries still do not have the ability of casting three-dimensional process design. [0004] 2. In the process of process design, the 3D model issued b...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, there is no ability to design three-dimensional casting process at home and abroad

[0004] 2. In the process of process design, it is impossible to directly use the 3D model issued by the design department to carry out process design

[0005] 3. During process design, it is necessary to convert the 3D model into a 2D graph, resulting in non-unique data sources, which cannot be associated with the product design model

[0006] 4. The process design is only based on the engineer's personal experience, there is no knowledge base for reference, successful cases cannot be shared with others, and knowledge accumulation cannot be formed

[0007] 5. The efficiency of process design is low, the quality is poor, and there is no means of verification, resulting in low yield and pass rate of the designed process

[0008] 6. The process design and process simulation are disconnected, the simulation parameters and process design parameters cannot be automatically transferred, and the workload of repetitive labor is large

[0009] 7. The visual expression of the process cannot be realized, and the operability and ease of implementation of the tooling cannot be evaluated, which brings inconvenience to production

[0010] 8. The rationality of the process can only be verified by actual production, but there is no means of evaluating whether the process has reached the optimum
