Communication and connectivity of an operational data collection are required principal. OPC Unified Architecture and standards like ISA95 are key resources to develop automated interfaces between equipment and manufacturing execution system (MES). The target is to integrate complex equipment in a convenient way through the use of a companion specification, a dynamic address space and a OPC UA client characterisation process. Challenges are the reconciliation of the right programming languages, the integration of generic, domain agnostic, domain specific and equipment specific information models. This study describes the generic approach and demonstrates its applicability in a complex manufacturing environment, serving as a blueprint for other environments. The outlined concept is based on C#/LabView source-code developed for semiconductor back-end equipment, which interacts with an MES. The proposed system is validated for a final-testing-unit in the production of kW-class high-power laser diodes.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48004462","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}

The main drawback is that machine tools generally offer reduced spaces for the actuator location close to the cutting point and, hence, a reduced volume design is required for this external device. Consequently, the ratio between the force capability and the occupied volume is of major importance. Therefore, the performance of the actuator must be exploited to the fullest, which depends principally on the selected control strategy to determine the force to be exerted. The work presents the comparison of the most used feedback control algorithms and a novel strategy based on the regenerative effect disturbance. Their results are assessed for orthogonal cutting cases, with the aim of optimising the behaviour of the active damping system.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41391370","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}

Required motions are imparted by any three-axis CNC machining centre exploiting serial communication interface, macro programming and machine data manipulation facilities. The device consists of three subsystems: laser beam, resin handling and micro-controller, making use of several sensors and actuators. For an approximately circular beam spot the G-code is generated by commercially available slicing software and is automatically modified to comply with the CNC machine controller's own automation functions. Alternatively, for line-shaped laser beams G-code can be directly generated from STL files by making use of profiling and hatching library routines. The device has been tested with two different power diode lasers for manufacturing a variety of parts. Curing rate was tested by micro-hardness measurement. Dimensional accuracy with respect to nominal was recorded using a white-light scanner, proving that acceptable accuracy is reachable.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41892748","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}

Furthermore, an acceleration-based disturbance observer (AbDOB) is designed to estimate disturbances acting on the positional dynamics of the quadrotor. For the attitude control, nested position, velocity, and inner acceleration feedback loops consisting of PID and PI type controllers are developed to provide high stiffness against external disturbances. Reliable angular acceleration is estimated through a cascaded filter structure. Simulation results show that the proposed controllers provide robust trajectory tracking performance when the aerial vehicle is subject to wind gusts generated by the Dryden wind model along with the uncertainties and measurement noise. Results also demonstrate that the reference attitude angles calculated through nonlinear optimisation are smooth and within the desired bounds.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46052262","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}

The deformations encountered in single grain simulations are severe, especially due to the large negative rake angles. Conventional software tools using FEM suffer from the induced extreme distortions of the grid, necessitating costly remeshing operations. Meshless methods are not limited in the amount of deformation they can reproduce and thus are a promising alternative, which also has the potential for extreme parallelisation on the graphics co-processor (GPU). With the drastically increased computational speed unprecedented simulation resolutions can be achieved at reasonable computation times allowing parameter studies on different friction and constitutive models with first order complete meshless formulations.

Typically, cutting forces are the most important factor affects the process outcome in terms of surface finish and chatter vibrations in milling of difficult-to-cut materials. The additively fabricated materials possess different mechanical properties hence their cutting force performance is usually unknown. For additively fabricated nickel alloy 625, the build direction and scan strategy rotation are known to influence the resultant workpiece structure with columnar grains. The peak milling force is found dependent upon the feed direction as well as the layerwise scan rotation employed in fabricating the workpiece. Feeding the cutter against the build direction resulted in lower peak forces with larger deviations, however feeding along the build direction resulted in higher peak forces with lower deviations. The build direction was also observable on fan shaped chip surfaces.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42239458","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}

Errors due to limited human capabilities hamper the precision of conventional impact tests using an impact hammer. Furthermore, impact tests on milling machines can be very time-consuming if dedicated parameter studies are performed, and also hazardous if impacts need to be performed on a rotating structure. To overcome these problems, a modularised and automated impulse hammer is presented in this paper. When using the automated impulse hammer, the variance in amplitude of subsequent impulses reveals to be one order of magnitude lower than when excitation is performed by hand. It is illustrated how the automated device can be used to investigate very distinct dynamic effects on a CNC machine that require a very high measurement precision, and also in which cases it helps to obtain more accurate stability chart predictions.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48706771","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}
