Siemens delivers Artificial Intelligence-powered CAD sketching technology

Siemens Digital Industries Software has a new solution for capturing concepts in 2D. The new NX Sketch software tool revolutionises sketching in CAD, which is an essential part of the design process. By changing the underlying technology, users are now able to sketch without pre-defining parameters, design intent and relationships. Using Artificial Intelligence (AI) to infer relationships on the fly, users can move away from a paper hand sketch and truly create concept designs within NX software. This technology offers significant flexibility in concept design sketching, and makes it easy to work with imported data, allowing rapid design iteration on legacy data, and to work with tens of thousands of curves within a single sketch. With these latest enhancements to NX, Siemens’ Xcelerator portfolio continues to bring together advanced technology, even within the core of modelling techniques, helping remove the traditional barriers users have experienced to dramatically improve productivity. The ability to make intelligent changes to 2D entities that one imports into the new sketcher is astounding,” said Steve Samuels, CEO of Design Visionaries Inc. Analysis has shown that in an average day or workflow, around 10% of a typical user’s day is spent sketching. In addition, within current design environments most concept sketching is happening outside of the CAD software due to the level of rules and relationships that must be decided on and built into the sketch by the user up front. Often designers in concept design stage do not necessarily know what thefinal product may be, which requires a sketching environment that is flexible and can evolve with the design. NX offers the flexibility of 2D paper concept design within the 3D CAD environment, as the first in the industry to eliminate upfront constraints on the design. Instead of defining and being limited by constraints such as size or relationships, […]

Ensuring a safe welding environment

Health and safety hazards are a critical consideration in any workplace for both the employer and employees, and the welding workplace is no exception. However, if safety measures are accurately implemented then much of the risk can be mitigated, if not fully eliminated. Welding can present numerous health risks to the eyes, skin and lungs. Bright light and ultraviolet radiation, toxic fumes and gases, noise as well as heat and fuel to ignite a fire are all hazardous by-products of the welding process. The correct risk assessment, implementation of procedures and the use of approved protective gear can however, make welding a safe procedure. Burns Burns are one of the most common injuries in welding and can occur on the skin and to the eyes. The intense ultraviolet and infra-red rays from welding can cause symptoms similar to extreme sunburn if a welder’s limbs are not covered. Hot spatters can also burn unprotected skin. All parts of the body including hands and feet need to be protected from burns. In the case of eye injuries, welding flash or arc eye is probably the most common eye injury among welders who refrain from wearing appropriate eye protection. While approved clothing, footwear and gloves will protect the limbs of a welder, the eyes and face can be safely protected by using the correct helmet. Helmets that feature Auto Darkening Filter lenses and passive lenses (Approved Coloured Glass welding lenses), such as those found in the Kemppi welding helmet range, provide 100% protection against bright light burns and ultraviolet radiation. Electrical Shock Welders can also suffer from electrocution if they come into contact with live parts. Welding involves the use of live electric circuits to create a pool of molten metal and therefore, the risk of electrocution is ever present. However, wearing the […]

Key technologies driving manufacturing transformation

While Covid-19 has been disruptive across industries, the manufacturing industry is presented with an opportunity to come out the other side stronger than before. Manufacturers must re-examine their processes and even their entire business model to find new efficiencies and ways to compete with offshore firms. As the sector moves closer to Industry 4.0, it is essential for manufacturers to be aware of the technologies that are likely to shape strategies and priorities across the next five years, according to Epicor Software. Greg O’Loan, regional vice president, ANZ, Epicor Software Corporation, said, “Manufacturing is a sector ideally placed to benefit from emerging technologies. Industry 4.0 is a global concept that predicts the manufacturing sector will experience a fourth industrial revolution, this time based on digital technology. “With the right solutions in place, manufacturers will be able to make smarter decisions, optimise processes, deliver a better customer experience and, ultimately, outperform their overseas counterparts. “To achieve this, decision-makers in manufacturing firms need to gain a thorough understanding of the solutions lining up to transform the industry in the next five years.” Epicor has identified the top four areas of technology that will drive digital transformation in the manufacturing sector: Artificial intelligence (AI) AI and data strategies are fundamental for all businesses, and organisations that do not already have a roadmap in place for AI could face an uphill battle to compete. Three-quarters of C-suite executives surveyed by Accenture said they believed if they did not scale AI in the next five years, they could go out of business entirely. (1) In manufacturing, AI can be used for everything from optimising production lines to automating defect checking, resulting in fewer costly defects and increasing overall productivity. Internet of Things (IoT) and 5G IoT solutions are continuing to gain rapid momentum in manufacturing […]

The future of thermoplastics

There are two major types of resin used in the production of composites — thermosetting and thermoplastic. Thermosetting resins are currently the most common, but as composite use expands, thermoplastic resins are increasingly being explored. Thermosetting resins are hardened via curing, using heat, to form heavily cross-linked polymers with insoluble or infusible rigid bonds that will not melt on exposure to heat. On the other hand, thermoplastics are branches or chains of monomers that soften when heated and solidify once cooled — a reversible process with no chemical bonding. Put simply, you can re-melt and re-form a thermoplastic, but not a thermoset. Why thermosets rule Thermosetting resins, such as epoxies or polyesters, are popular for composite production because their low viscosity helps achieve good penetration into the fibre network. This allows for the use of more fibres and increases the strength of the final composite material. The process for a thermosetting resin begins, in the pultrusion process, with the fibres being immersed in resin, which are then pulled into a die where heat is applied. This starts the curing reaction that converts the low molecular weight liquid resin into solid three-dimensional network structure, locking the fibres into this newly formed network. Because most curing reactions are exothermic, once the reaction has begun it will readily propagate, making thermoset production easily scalable. Once set, the three-dimensional structure locks the fibre in place and gives the composite its strength and rigidity. The rise of the thermoplasticThermoplastics and thermoplastic composites have been around for some time, especially for short fibre applications. But new attention is being drawn towards thermoplastics, due to the rising need for additional light weighting without the loss of structural stability, especially in the automotive industry. One specific example is the potential to use thermoplastic composite to reduce the weight […]

Can we be more productive?

By Ian Walsh, Managing Director, Intent Group Over the past 50 years, New Zealand has been on a negative GDP trajectory versus the OECD, sliding from 5th place to 22nd! The top 10 countries average 60% more productivity per person per capita in US$ than we do, and this gap has been widening since the mid 1980’s.* The general consensus is that we work hard, and the statistics say we work more hours than most. Clearly this is the harder not smarter argument. Perhaps Sir Paul Callaghan captured it best when he said, “In New Zealand we sense, somehow we are not as prosperous as we would like.” Without highly productive businesses we will not be able to generate the income to invest in human and physical capital, to create the society and country we aspire to. So why are we less productive? There has been a lot of research over the years, with the traditional arguments being that our costs are higher as we are further away from market. The research, however, shows that we should be 20% above the average** and playing in the top 10, but we are not. This is due to: Weak international connections. New Zealand firms face reduced access to large markets and limited participation in global value chains, where the transfer of advanced technologies now often occurs. Underinvestment in “knowledge-based capital”. In particular, R&D undertaken by the business sector is among the lowest in the OECD, reducing the capacity for “frontier innovation” and the ability of firms to absorb new ideas developed elsewhere (“technological catch-up”). The quality of management in New Zealand is low, which decreases the productivity gains from new technology. I find these outcomes interesting, but not surprising. 90% of NZ businesses are SME’s who can’t afford HR or a training manager, let alone an innovation manager! Most investment is managed by the entrepreneur who started the […]

Revolution Fibres skincare product sells out in South Korea

A natural New Zealand skincare product has sold out in online sales after just two hours on South Korea’s most influential home shopping network. The manufacturer of the skincare product, Auckland-based nanofibre producer Revolution Fibres, has now switched its production capacity to face masks to meet COVID-19 demand and to increase the local supply of critical Personal Protective Equipment (PPE). Ray Connor, Revolution Fibres CEO, says while the South Korea campaign was successful, following the COVID-19 announcements Revolution Fibres priority switched to manufacturing filter media for N95 face masks. “Filtration for respiratory protection from pollution and viruses is what Revolution Fibres made its name on 10 years ago. We have the expertise and we are increasing our capacity to fulfil large scale orders for face masks which are increasingly in demand.” With AcitvLayr now sold out in South Korea, Revolution Fibres will ramp up production of the skincare product once the lockdown is finished in New Zealand alongside the continued manufacture of filter media for face masks. ActivLayr is made from premium marine collagen and was developed through an intensive research and development programme over several years, with funding support from the Seafood Innovations Ltd and in collaboration with Sanford and Plant & Food Research. ActivLayr was advertised on influential South Korean home shopping channels GS and Lotte across two hour-long segments showcasing the skincare product to tens of millions of consumers. The advertising campaigns for ActivLayr focussed on the premium Tier 1 marine collagen combined with hyaluronic acid (an ingredient to help the skin retain moisture) to deliver an advanced cosmetic application. The ActivLayr technology is a versatile platform and has been shown to effectively and efficiently deliver a broad range of active ingredients directly into the intradermal and subdermal regions of the skin.

Robotics tutor creates real time map of PPE demand

As part of his volunteer work for ShieldsUp, an organisation established at the start of lockdown which called on volunteers to 3D print personal protective equipment (PPE) to fill the shortage gap, WelTec tutor Frank Beinersdorf has developed a real time map of how many, and where, protective shields are needed across New Zealand. Frank’s map is what Shieldsup uses to determine how many shields need to be made, and provides information to the many volunteers tasked with delivering the equipment. Using various icons, the map displays priority of orders, what orders are ready to go, or are on the way, and a heat map of what is still needed. There is also a visual chart to demonstrate demand over time and a chart tracking Covid cases in New Zealand. The map and information can be found here: https://beinerf.github.io/. “Frank’s work became invaluable as we grew beyond lists and text,” says Tim Carr, ShieldsUp founder. “What he did in regard to visualising a rapidly growing data set has allowed us to see where resources were needed and demand was growing.” ShieldsUp is a community driven initiative, conceived from the outcry of medical and emergency responders facing COVID-19 head on, as they put their own health at risk in their jobs to help protect others, often without the personal protective equipment they so desperately needed. As well as providing information on numbers and location of PPE required, Frank has also converted the data into useful quick facts, kept up to date real time. For example, on Tuesday May 5th, over 18, 000 shields were still needed, 22 242 were wanted and 16, 521 had been made and delivered by 254 volunteers across New Zealand. In the spirit of community from which ShieldsUp was created, Frank included fun facts in his data […]

What is Generative Design?

At a high-level, Generative Design is relatively simple. It is a capability of CAD applications that autonomously generates a number of design alternatives given a set number of constraints. This can be done without an engineer’s guidance or interaction, freeing them up for other tasks. Once complete, the engineers can choose which designs they want to explore more completely. In all, this accelerates the design process without detailed attention from the engineer.

Siemens NX 12 generative design software embeds topology optimisation powered by convergent technology which enables unified 3D modelling capability on combinations of Facet and B-rep data. This results in lighter components without sacrificing design intent or integrity. Empowering engineers with Generative Design and facet modelling Generative Design is an cad engineering software function in which a designer collaborates with artificial intelligence algorithms to generate and evaluate hundreds of potential designs for a product idea. The Generative Design process starts with defining the goals and constraints of the project. These include, but are not limited to, design parameters such as: ⦁ product size or geometric dimensions ⦁ permissible loads and operating conditions ⦁ target weight ⦁ materials ⦁ manufacturing methods ⦁ cost per unit Benefits of building with Generative Design process By using Generative Design, engineers can create and simulate thousands of designs (many of which they may not have envisioned on their own) in a fraction of the time it would normally take. As additional benefit, the Generative Design process can yield highly […]
