标题:Perfecting production in SMEs using Industry 4.0

参考译名:利用工业4.0完善中小企业生产

简介:As everything is becoming increasingly more digital focused in recent years, it means the way things work is constantly changing and evolving. It comes as no surprise that the way businesses are run - and their productivity - is changing too. The idea of the fourth industrial revolution (otherwise known as Industry 4.0), allows digitalisation to connect all actors in the value process by fusing the production with information and communication technology. This can seem overwhelming – especially if you’re responsible for your organisation’s investment decisions.

标题:May 2019 Manufacturing Business Outlook Survey

参考译名:20195月美国制造业前景展望

简介:Results from the May Manufacturing Business Outlook Survey suggest continued growth for the region’s manufacturing sector. The survey’s indexes for general activity, shipments, and employment increased from their April readings.  The new orders index remained positive but decreased modestly. The survey’s future activity index, after falling in recent months, was little changed, while the firms’ forecast for future employment improved.

Current Indicators Suggest Continued Growth

The diffusion index for current general activity increased from 8.5 in April to 16.6 this month (see Chart 1). Over 25 percent of the manufacturers reported increases in overall activity this month, while 9 percent reported decreases. The indexes for current shipments and new orders moved in opposite directions this month: The current shipments index increased 9 points, while the new orders index fell 5 points. The current inventories index fell 6 points to its first negative reading in four months.

标题:Advances in Green Steel Making Technology - A Review

参考译名:绿色钢铁制造技术的进展-综述

简介:The aim of this research work is to increase the quality, productivity of steel and to reduce the CO2 emissions from the global manufacturing sector. On average, the production of one ton of steel generates about two tons of CO2 emission. The main cause for energy inefficiency and environment pollution are outdated steel production technology in use. The green steel is a new steelmaking process lowers green house gas emission, cuts costs and improves the quality of steel. The new process is known as molten oxide electrolysis and the clever use of iron-chromium alloys. When we are using molten oxide electrolysis to create oxygen from the iron in lunar soil and steel was created as a byproduct of steel. This process is limiting carbon emissions. This concept is fundamental to the triple bottom line concept of sustainability, which focuses on the interplay between environmental, social and economic factors. The production of steel results in the generation of byproducts that can reduce CO2 emissions by substituting resources in other industries. The implementation of green manufacturing focused on investigating the energy saving & CO2 emission from producing steel & effective utilization of recycling of steel scrap as a way of sustainable development in steel industry.

标题:Experimental investigations and optimization of forming force in incremental sheet forming

参考译名:板料增量成形中成形力的试验研究与优化

简介:Incremental sheet forming process has been proved to be quiet suitable and economical for job and batch type production, which exempts expensive and complex tooling for sheet forming. Investigation of forming forces becomes important for selecting the appropriate hardware and optimal process parameters in order to assure perfection and precision of process. Moreover, lack of available knowledge regarding the process parameters makes the process limited for industrial applications. This research paper aims at finding out effectsof different input factors on forming forces in single-point incremental forming (SPIF) process. For operation sustainability and hardware safety, it becomes critical to optimize forming forces for a given set of factors to form a particular shape. In this study, optimization of input factors has been performed to produce conical frustums with helical tool path using Taguchi analysis as design of experiment (DOE) and analysis of variance (ANOVA). The optimal experimental conditions for forming forces have been calculated as sheet thickness(0.8 mm), step size (0.2 mm), tool diameter (7.52 mm), tool shape (hemispherical), spindle speed (1000 rpm), feed rate (1000 mm/min) and wall angle (50 o ). Effects of tool shape and viscosity of lubricants have also been investigated. An intensive understanding of the mechanism of forming forces has been presented, which shows that force trend after peak values depends upon instant input factors that can be categorized as a safe, severe and crucial set of parameters.

标题:Has Electronic Stability Control Reduced Rollover Crashes?

参考译名:电子稳定控制减少了翻车事故吗?

简介:Vehicle rollovers are one of the more severe crash modes in the US - accounting for 32% of all passenger vehicle occupant fatalities annually. One design enhancement to help prevent rollovers is Electronic Stability Control (ESC) which can reduce loss of control and thus has great promise to enhance vehicle safety. The objectives of this research were (1) to estimate the effectiveness of ESC in reducing the number of rollover crashes and (2) to identify cases in which ESC did not prevent the rollover to potentially advance additional ESC development.

All passenger vehicles and light trucks and vans that experienced a rollover from 2006 to 2015 in the National Automotive Sampling System Crashworthiness Database System (NASS/CDS) were analyzed. Each rollover was assigned a crash scenario based on the crash type, pre-crash maneuver, and pre-crash events. The Insurance Institute for Highway Safety ESC availability database was matched to each NASS/CDS case vehicle by the vehicle make, model, and model year. ESC effectiveness was computed using the quasi-induced exposure method.

标题:Sandvik creates 3D printed diamond composite

参考译名:山特维克创造出3D打印的钻石复合材料

简介:The company says that the composite is perfect for industrial use owing to its hardness, heat conductivity, low density, thermal expansion and corrosion resistance. This is despite differing from synthetic or natural diamonds through being a composite material, with diamond cemented in a very hard matrix material that ensures it is printable while still retaining its diamond-like properties.

标题:Virgin Orbit Researching Multi-Metal AM with NASA

参考译名:维珍公司和美国宇航局一起研究轨道用多金属增材制造

简介:Much like SpaceX, world-famous conglomerate Virgin is also diving head-deep into space exploration at the behest of a famous billionaire/entrepreneur. Richard Branson’s dynamic brand features Virgin Orbit, specialising is aerospace and launch solutions for small satellites. Now, they’re expanding into 3D printing research to further their outer-spacefaring ambitions. With the aid of NASA, Orbit will be looking into multi-metal additive manufacturing for more efficient engineering solutions.

More specifically, both companies are joining together to develop a feasible means of building multi-metallic combustion chambers. Combustion chambers perform a crucial duty with highly dangerous parts to bolster the propulsion process. The chambers mix together propellants and ignite the mixture producing optimum pressures and temperatures. As one can imagine, this makes combustion chambers one of the most arduous engine parts to develop at cost-efficient levels.

标题:Sandvik Announces World’s First 3D Printed Diamond Composite

参考译名:Sandvik宣布推出全球首款3D打印金刚石复合材料

简介:There have been several big unveilings at RAPID + TCT 2019, but Sandvik’s announcement may outshine the rest: a 3D printed diamond composite. Actually, the composite doesn’t shine like diamond, but it’s just as strong and wear resistant. Industrial manufacturing and machining will forever change with this discovery.

Historically, 3D printing in diamond was something that none of us imagined was achievable. Even now we are just starting to grasp the possibilities and applications that this breakthrough could have,” said Anders Ohlsson, Delivery Manager at Sandvik.

Diamond is 58 times harder than any natural material so it’s no wonder material scientists have been trying to harness it for industrial uses. Diamond composites have been available since 1958, but shaping the material is very difficult since machining diamond is nearly impossible. With Sandvik’s technology, diamond composites can now be fabricated into complex forms, even parts with internal cavities.

标题:A modified genetic algorithm for time and cost optimization of an additive manufacturing single-machine scheduling

参考译名:一种改进的遗传算法用于增材制造单机调度的时间和成本优化

简介:Additive Manufacturing (AM) is a process of joining materials to make objects from 3D model data, usually layer by layer, as opposed to subtractive manufacturing methodologies. Selective Laser Melting, commercially known as Direct Metal Laser Sintering (DMLS?), is the most diffused additive process in today’s manufacturing industry. Introduction of a DMLS? machine in a production department has remarkable effects not only on industrial design but also on production planning, for example, on machine scheduling. Scheduling for a traditional single machine can employ consolidated models. Scheduling of an AM machine presents new issues because it must consider the capability of producing different geometries, simultaneously. The aim of this paper is to provide a mathematical model for an AM/SLM machine scheduling. The complexity of the model is NP-HARD, so possible solutions must be found by metaheuristic algorithms, e.g., Genetic Algorithms. Genetic Algorithms solve sequential optimization problems by handling vectors; in the present paper, we must modify them to handle a matrix. The effectiveness of the proposed algorithms will be tested on a test case formed by a 30 Part Number production plan with a high variability in complexity, distinct due dates and low production volumes.

标题:US Firms Rethink China Presence Due to Trade War: Survey

参考译名:调查:美国公司因贸易战重新考虑在中国的状况

简介:The American Chamber of Commerce found that nearly half of U.S. businesses in Chain have experienced non-tariff retaliatory measures in China since last year. Most U.S. businesses in China are hurting from the tariffs war between the two countries, forcing some companies to relocate abroad or refocus their business, a survey showed on May 22.The recent poll by the American Chamber of Commerce in China and its sister organization in Shanghai paints a gloomy picture of the business environment for American companies.Three-quarters of the 250 respondents said increases in  U.S. and Chinese tariffs are having a "negative impact" on their business as orders were drying up owing to rising manufacturing costs and prices.

标题:Turning the Tables: Thermally Conductive Plastics

参考译名:颠覆传统的概念的导热塑料

简介:Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitts or a Styrofoam coffee cup, both items are manufactured from polymer-based materials that are excellent at trapping heat.Now, engineers from Massachusetts Institute of Technology (MIT) have flipped this image of polymer plastics as insulators by fabricating thin films polymers that actually conduct heat. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than ceramics and many metals such as steel.The team’s results may spur the development of polymer insulators as lightweight, flexible, and corrosion-resistant alternatives to traditional metal heat conductors, with applications ranging from heat dissipating materials in laptops and cellphones to cooling elements in cars and refrigerators.

标题:Researchers Create Soft, Flexible Materials With Enhanced Properties

参考译名:研究人员创造了具有增强性能的柔软、柔性材料

简介:A team of polymer chemists and engineers from Carnegie Mellon University have developed a new methodology that can be used to create a class of stretchable polymer composites with enhanced electrical and thermal properties. These materials are promising candidates for use in soft robotics, self-healing electronics and medical devices. The results are published in the May 20 issue of Nature Nanotechnology.In the study, the researchers combined their expertise in foundational science and engineering to devise a method that uniformly incorporates eutectic gallium indium (EGaIn), a metal alloy that is liquid at ambient temperatures, into an elastomer. This created a new material—a highly stretchable, soft, multi-functional composite that has a high level of thermal stability and electrical conductivity.

标题:A “Building to Win” Strategy for Congress and President Trump

参考译名:美国国会和特朗普总统的为赢而建战略

简介:Great nations build and invest in great infrastructure. Too many 21st-century U.S. infrastructure systems depend on 20th-century investments. Now in an alarming state of disrepair and in urgent need of new funding, America’s infrastructure can no longer wait. Families, communities and manufacturers need modern transportation, energy, broadband and water infrastructure to meet the demands of today’s economy. The modern manufacturing economy we are building does not have the kind of infrastructure we need to support our vision for an exceptional America.For generations, manufacturers have risen to the occasion to meet great challenges, to give more Americans a chance to improve their lives and build our nation for the future. Now, it is time again for our leaders to follow our example and strengthen the foundation that makes our work and our daily lives possible: our nation’s infrastructure.

标题:SPACE CLIMBING ROBOT FEET WITH MICROARRAY STRUCTURE BASED ON DISCRETE ELEMENT METHOD

参考译名:基于离散元法的微阵列结构空间攀登机器人足部

简介:Aiming at the on-orbit maintenance requirements of spacecraft, this paper proposed an updated type of space climbing robot that can climb onto the target spacecraft in space environment for repairing and rescuing. The robot's movement system consists of piezoelectric driving legs and micro-adhesive feet. The robot leg and body connection have two degrees of freedom, the knee joint has one degree of freedom, and the ankle joint has two degrees of freedom. In space environment with no gravity, the climbing robot can over obstacles by crawling movement and flipping movement. The clamping force of the robot is provided by the adhesion of the robot feet with microarray structure. The robot foot-end microarray adhesion structure was designed based on the multi-scale microstructure of the gecko's sole. The effects of the structural parameters, such as the contact area, length-diameter ratio, length, diameter, and density, on the adhesion characteristics of the microarrays in zero-gravity space environment were analysed. The simulation model was established using the discrete element software EDEM. The normal and tangential adhesion of the microarray in different motion modes is obtained by simulation. The simulation results demonstrate that using different ways of movement can achieve different adhesive abilities. The above conclusion supports the theory of the later achievement regarding robot feet's strong attaching and rapid detaching ability.

标题:Task Space Torque Profile Adaptations for Dynamical Human-Robot Motion Transfer

参考译名:用于动态机器人运动传递的任务空间扭矩曲线自适应

简介:Motion transfer from a human to a robot implies accurate tracking of desired, demonstrated trajectories. However, direct imitation of joint position trajectories might not result in similar behavior of the robot and the human, because they have different kinematic and dynamic properties, i.e., different embodiment. To avoid the correspondence problem, the demonstrated trajectories need to be somehow adapted. In this paper we go beyond simple imitation, but we show how the torque profiles that should execute the demonstrated position trajectories are being learned in a manner that preserves the correspondence. Thus, position trajectories are modified from the demonstration and, furthermore, the robot executes the motion that preserves correspondence in a compliant manner. Because it is compliant, the robot is safer for the nearby person or environment, as potential unforeseen collisions will result in lower impact forces. We show the results of motion transfer of squatting from a human to a simulated CoMaN humanoid robot.
