Although, other methods such as minimum quantity lubrication have been sought but the harmful effects of metal working fluids persist. This study however focuses on the design, fabrication and testing of a thermosyphon drill for eliminating the use of metal working fluids in drilling operations. The methodology included the design of a taper thermosyphon drill, analysis of the thermosyphon drill, manufacturing and testing of the thermosyphon drill. A virtual design and stress analysis of the reversed tapered thermosyphon was done using SolidWorks software. A high speed steel drill bit was manufactured to suit the design requirements of the thermosyphon. The thermosiphon was then fabricated within the machine shop floor using Electric Discharge Machining through method of spark erosion. A reverse tapered thermosyphon was designed to improve the optimal performance of the drill. The reversed tapered thermosyphon specification includes a 20 mm diameter drill, a length of 140 mm and web thickness 7mm, with a taper thermosyphon of 6.48 mm large diameter and 2.5 mm small diameter on a length of 114 mm. The optimal position stress analysis shows that the tapered thermosyphon drill experienced a Von Mises Stress of 38.4 MPa for the cutting distance from the drill tip and 372°C for the optimal temperature. The optimal position stress analysis also showed a Von Mises Stress of 17 MPa for the largest taper diameter and 433°C for the optimal temperature. The thermosyphon drill bit was manufactured and tested against the dry drill and metal working fluid drill bit. The results displayed a reduction in drill bit peak temperatures on the drill bit tip of about 40% for the dry drilling and thermosiphon drilling processes.","PeriodicalId":377249,"journal":{"name":"2020 IEEE 11th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614326","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}

A common approach in design of mechatronic systems is based on a sequential method, where different disciplines are treated and designed separately. This paper extends earlier work on integrated physical and control design optimization with integrating an additional aspect of the corresponding embedded control system implementation. Our previous publications describe integrated design optimization through a few specific use cases but the impact of embedded control implementation on the structural design of the systems is neglected. In this paper, the approach is extended to cover discussions on control implementation and its effect on the physical dimensioning and vice versa. A multi-objective optimization approach is implemented and tested on a mechatronic system case study consisting of a DC-motor, a planetary gear, a flexible shaft, an embedded controller and a load. The couplings between the properties of different engineering domains are studied and highlighted. The presented approach which is aimed for early phases of design, considers the integration of three engineering disciplines in one design framework which so far has been missing.","PeriodicalId":377249,"journal":{"name":"2020 IEEE 11th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122526322","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}

Resistive memories based on metal oxide thin films have been extensively studied for application as next generation nonvolatile memory devices since they have several advantages, such as good scalability, low-power consumption, and fast switching speed. However, the fabrication of metal oxide based memristors usually consists of conventional physical vapor deposition (PVD) techniques and lithography which are expensive, time consuming and complicated in nature. In this paper, we report the successful fabrication of ZrO2 based memristor using electrospray deposition (ESD) and electrohydrodynamic printing (EHDP) techniques which are cost-effective, room temperature techniques. The Ag electrode has been patterned on glass substrates through EHDP technique and the active layer of ZrO2 has been spray deposited on the Ag electrode followed by the patterning of top Ag electrode. The resistive switching properties of ZrO2 layer with Ag electrodes was investigated in this study.","PeriodicalId":377249,"journal":{"name":"2020 IEEE 11th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122336928","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}

Samples were rolled for two passes. In ARB process, thickness is reduced by 50% for each pass. The aim of performing the ARB process was to refine the grain structure of aluminum 1050-H4 to increase its tensile strength. A tensile test was performed at room temperature and at a steady strain rate with the aim of determining whether ARB increases the mechanical properties of aluminum 1050-H4 and identify the moment the material experience high ultimate tensile strength. Samples were cut according to standard test methods for tension testing of metallic material (ASTM) at rolling direction (RD). Information about the microstructure of samples was obtained using a scanning electron microscope (SEM). The highest UTS was obtained on the 1st pass and was reported as 127.1 MPa and the lowest UTS was discovered on parent sample and reported as 111.7 MPa. It was also observed that E-modulus and percentage elongation decreased due to the ARB process. It was noticed that after several rolling process, material surface temperature increases.
