The paper presents a dispersing NC system for a novel hybrid machining robot. For this purpose., three issues are clarified., i.e. the architecture., the control strategy and the software of NC system. Firstly., by adopting a multi-axis motion control unit (MCU)., the architecture of a dispersing NC system is designed. Secondly., a control strategy is presented based on tool-path smooth algorithms., kinematics model and kinematic calibration method. By embedding above control strategy., a post-processing software and a human-machine interaction (HMI) software are developed. Finally., a NC system is developed to construct a hybrid machining robot system. A set of kinematic accuracy tests and machining tests are carried out to verify the feasibility of the developed NC system.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125049982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increasing number of exceptional events during manufacturing, those mechanisms might eventually fail to react timely to situations of multiple resource conflicts. In this work, we discussed the social networks consisting of various manufacturing resources and provided the relevant modeling techniques including the Resource Description Framework and the Finite State Machine. The function and behavior models can support the autonomous interactions and collaborations among resources, while the communication hub connected the resources and formed a peer-to-peer network. On this basis, the dynamic features of manufacturing networks including the exception propagation phenomenon can be analyzed. A case was studied to identify the bottleneck resources using the complex network theory. This work has provided an analytical platform to optimize manufacturing resources using complex network and graph theory.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134137023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To analyze the stiffness of such complex mechanical mechanism, finite element method can be used for simulation. Based on Abaqus finite element software, the stresses and deformations of the handling robot, especially its lifting system, were analyzed under rated working conditions; the stresses and overall deformations of key parts of the lifting system were obtained. The analysis results showed that the maximum stress and deformation of the lifting system did not exceed the predefined targets.

For demolition robots operating in non-structural environments, their tracking process will have the problems of randomly appearing tracking targets being obscured and a complex background environment. The paper solves this problem by extending the Camshift algorithm to 3D space, using depth information to separate occluders and targets in space. Through experiments, it is proved that this method can effectively solve the problem that the tracking of the end of the robotic arm is lost due to random occlusions during the positioning and tracking of the end of the robotic arm, so as to provide the feedback information of the spatial position of the end of the robotic arm for the autonomous positioning of the robotic arm in a real-time and stable manner.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116642364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the existence of multi-source deviation and multi-point assembly of the same part in the assembly of the rotary table, the tolerance chains are more complex, and the assembly result depends on workers to correct during installation at site, resulting in low efficiency and low assembly accuracy. A three-dimensional tolerance modeling method was established based on the Jacobian-Torsor theory. A parallel assembly model was established under multi-point assembly, and the relationship between various deviation sources and assembly deviations is obtained. The contribution of each dimension chain error to the total error is obtained by Monte Carlo analysis, which provides a basis for the designer to allocate tolerance. After several times of iteration procedure, the calculated FR meets the threshold required for product assembly. This method can effectively improve the efficiency of assembly.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114879602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Robots play an important role in automobile manufacturing. In the process of automobile manufacturing, the performance and quality of the product largely depend on the size accuracy of the parts, so edge information needs to be tested before the product is produced and assembled. At the same time, in the field of path planning, people need to obtain geometric feature information such as the edge of components in advance. However, large components are due to various the accuracy of the error needs to be scanned on the spot, and then processed after obtaining the point cloud. In this paper, a new method for quickly extracting edge contours from large-scale point clouds is studied. In the process of finding edges in two-dimensional images, some optimizations have also been made to make them more suitable for edge extraction of such plane structures.

Combining the advantages and disadvantages of the two methods, an algorithm combining vision and laser repositioning is proposed. Firstly, vision is based on ORB feature matching to do the preliminary localization, and an artificial bird swarm algorithm is proposed to improve the accuracy of local localization when the prior location is known. The experimental results show that the proposed algorithm shortens the relocation time by one order of magnitude compared with the pure laser localization algorithm, and improves the localization accuracy by one order of magnitude compared with the pure vision algorithm.","PeriodicalId":202270,"journal":{"name":"2022 5th World Conference on Mechanical Engineering and Intelligent Manufacturing (WCMEIM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121155167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
