Articles - Design for Manufacturing: Guidelines for Sheetmetal Fabrication. Perfect sheetmetal-fabrication designs—those that avoid engineering change orders (ECOs)—evolve only when designers take care to consider the capabilities of the equipment on the shop floor.
For example, a designer may assume that hole and shaft diameter should match, thinking that a 50-mm-dia. shaft should fit into a 50-mm-dia. hole punched into a sheetmetal cover. However, the shaft will not fit into the hole; in fact, it will just sit on the circumference of the enclosure. To allow the shaft to sit on the hole seat, the hole and shaft both require dimensional limits and tolerances, based on the type of fit needed—clearance fit, interference fit or transition fit. In addition, when punching the hole, the tooling will create impressions on the sheetmetal, potentially leaving excessive burrs. This is one example of how reality can deviate from ideal conditions. CAD Essentials for Fabrication at the Tipping Point of Industry 4.0.
Sheet metal fabricators: Evaluating the odds of success with Industry 4.0 - Automation. Industry 4.0 is driven by the interconnectivity of machines and intelligence derived by the aggregation of data obtained from manufacturing operations.
Production houses have become more sophisticated. And the repercussions of industry 4.0 are directly seen in ways CAD designers sketch or model; conduct research and development and executing manufacturing operations, to varying degrees. What interests sheet metal fabricators is finding out the impacts of this whole idea of Industry 4.0 on their business – good or adverse?
As far as adversities are concerned, none are seen at this stage of laying the foundation, and aren’t predicted in near future; of course apart from the challenges in adopting new technologies, developing skill sets and shifting to CAD platforms – one fundamental need. If that is sorted, Industry 4.0 do bring any concerning challenges. Odds of Industry 4.0 being a success for sheet metal fabricators So what are the odds of well-being for fabricators? Why CAD Models Need Standard Visibility for Precision Part Manufacturing - Digital Engineering. Precision part manufacturers face challenges that are related to the shop floor as well as the designs.
The majority of these challenges are because smaller parts or units are both bespoke and have precise geometry. To be able to design and develop bespoke and precise manufacturing information, engineers need a CAD system that is democratized. In other words, everyone from the design engineer to the foremen on the shop floor, and everyone in between, should be able to view the CAD model. Rapid Prototyping: In-House or Outsourcing? A CFD Approach for Design and Development in Oil & Gas Industry. Nov 28, 2016 -- Engineers most often rely on analytical modeling for engineering design and analysis performed using equations to obtain solution for a problem in consideration.
While analytical modeling assists engineers to understand the physics involved in the product operation, it increasingly becomes complex when trying to model phenomena with more complexity. To simulate and predict the behavior of complex 3D fluid flows, industry relies more on the powerful technique called Computational Fluid Dynamics (CFD). The technique makes use of complex differential equations to solve fluid flows involving turbulence, heat transfer, phase changes or chemical reactions. From its first commercial use since 1980s, CFD is extensively applied today in industries like oil & gas, apart from aerospace and automotive, as it allows engineers to optimize equipment designs quickly. Vital applications of CFD that can help in keeping the plant efficient and functioning: Why SolidWorks Over Other CAD Tools? Product Development Posted by Kashyap Vyas on November 23rd, 2016 Globally, manufacturers of consumer products, industrial equipment, automotive parts and construction equipment rely on SolidWorks intuitive CAD modeling and virtual prototyping capabilities.
From conceptual modeling, 2D drawings and detailed 3D modeling to design automation, animation and manufacturing documentation, SolidWorks is indeed the first choice of design engineers across the globe. While some manufacturers have their own in-house resources, others prefer to hire SolidWorks certified drafting and modeling professionals, to meet the product development requirements.
Either ways, SolidWorks still holds a major share in the CAD market. Challenges for the Digital Twin concept. Industry 4.0, often known as the Internet of Things (IoT), is supposed to help the manufacturing landscape undergo a massive overhaul to improve revenues, optimize worker productivity and increase operational agility to meet demanding market conditions.
The “digital twin” concept is becoming a part of this productivity improvement and decision making process by connecting the silos between digital data. But part of the challenge with this concept is that industry leaders define the concept differently. The digital twin was first introduced and clearly defined by Dr. Utilize CFD for Wind Load Estimation on Offshore Platforms.
Offshore platforms are designed considering the effects of wind loads on the structure, to ensure its safety and reliability.
It is important to perform wind load estimation early during the design phase to avoid changes in the design later during the development stage. Conventionally, wind load estimations are performed in a wind tunnel, but these tests can only be performed once the platform design has reached to a level that can be defined. Thus, there is only limited information available with the design engineer during initial stages. Late changes in the configuration further introduce uncertainty as any change will affect the stability of the platform against wind loads.
