Delcam’s ArtCAM Pro CADCAM software for artistic applications has made it much easier to create complex designs, with a new approach called interactive distortion modelling. This allows users to distort either vectors or reliefs within ArtCAM models by bending or stretching the design, and to see the results in real time. Unlike most other CADCAM systems, ArtCAM Pro is aimed at skilled artisans rather than engineers and requires little knowledge of engineering or computing. It has been particularly successful in the signmaking, woodworking and engraving industries. In these areas and in other artistic applications, ArtCAM Pro allows users to increase productivity, improve quality and deliver new designs more quickly, by combining their craft skills and creativity with the power and precision of computer-aided manufacturing. The addition of interactive distortion modelling in the latest release makes ArtCAM’s unique free-relief modelling even more powerful. Interactive distortion modelling makes it possible to create the most complex shapes quickly and easily, with the ability to see the effects of any changes as they are being made. Once the design of the particular element has been finalised, it can be moved, rotated, rescaled and copied, either individually or as part of a group. Any part of the design can be isolated, edited and then recombined into a group for duplication or further editing within the group. At any stage in the process, either individual items or a group of items can be saved within ArtCAM Pro’s clipart library for use in future projects. A second major focus in the new release is on vector creation and editing. New snapping options make vector creation much quicker. They include the ability to snap to anything in the design, including any point on a vector, intersections between vectors, guidelines and key points within a model, such as the […]

Sistema has imported a 1,300 and a 650 tonne injection moulding machine to boost its manufacturing operations in New Zealand, allowing the company to create a new range of durable plastic home and office storage products made exclusively for The Warehouse. The 1,300 tonne machine is one of the biggest of its type brought into New Zealand during the last 20 years according to Sistema’s managing director Brendan Lindsay. “This equipment is a one-of-a- kind industrial machine. I have not heard of any other company bringing in a similar machine to manufacture products like this in New Zealand.” “This investment has allowed us to diversify our product offering and produce heavy duty storage containers ranging in capacity from 14 to 90 litres. The range will include utility trays and organiser tubs, filing clips and removable wheels, making them the most sophisticated plastic box storage system on the market,” said Mr Lindsay. The company is proud to collaborate with The Warehouse to bring this newest offering to the public, with the storage range going on sale this month. TW Group CEO Mark Powell considers this a smart business move. “We have formed a long term partnership with Sistema to support the development and manufacture of this product, which reflects our commitment to stock New Zealand made products.” Sistema’s business has evolved dramatically growing from a simple backyard garage operation 30 years ago to an international success story today. “We now export our products to more than 65 countries around the world, including the United States, the UK, Europe and South Africa, but we are committed to keeping our manufacturing in New Zealand,” said Mr Lindsay. In March 2012, Prime Minister John Key opened Sistema’s new $7.5 million purpose-built production factory, allowing the company to establish an additional 50 jobs. The company currently employs more than 540 staff.

What are the benefits of automation? There are a number of immediate benefits to automation. The one that is often sited is cost reduction through the lowering of labour costs. This can be a big driver, however is sometimes not a significant as most people assume. The main benefits that we find are that we are able to produce a highly repeatable, high quality, product quickly to the market. It is very important in a lot of the products that we are producing that they are repeatable. This means that our customers know that they are getting a product that will work for them every time and allow them to work within very tight constraints. This repeatability also ensures that the quality is consistent, even with the best trained labour force there are quality issues that arise from human error and hand producing product. Automation also allows us to produce at much higher speeds than human labour can achieve. Being able to turn orders around and get them back to the customer in short time frames is a huge advantage to any business that has any degree of lean or efficient manufacturing processes. Through automation we are also continuously upskilling our workforce. This is through both retraining to run more complex machinery, and also in understanding some complex lean manufacturing techniques that come with automation and continuous improvement. And does automation mean that workers can be more productive? Yes, there are a number of reasons why automation enables staff to be more productive. The most basic is that anyone using machinery can complete a job much faster. Machines are more accurate, tire less and can complete simple actions much faster than humans. Where we tend to find we get real productivity gains is when an operator is able to manage […]

  PIC CAP: Delcam for SolidWorks offers Delcam’s proven machining algorithms fully integrated into the SolidWorks environment. Delcam has launched the 2016 release of its Delcam for SolidWorks integrated CAM software for SolidWorks. This includes a range of enhancements, in particular more options for the Vortex high-efficiency area-clearance strategy, faster creation of multiple set-ups, more efficient turning and user-interface improvements to make programming even easier and faster. Full details on the new release, including video demonstrations of the main enhancements, are on the Delcam for SolidWorks Learning Zone – www.delcam.tv/dfs2016/lz Delcam for SolidWorks offers Delcam’s proven machining algorithms, which are already used by more than 50,000 customers, fully integrated into the SolidWorks environment. The program looks and behaves like SolidWorks, and offers full associativity so that any changes in the CAD model are reflected automatically in the toolpaths. However, this associativity is more intelligent than that offered in many other integrated CAM systems. Delcam for SolidWorks doesn’t simply modify the existing toolpaths but also reviews the choice of cutting tools and machining strategies, and changes them if necessary. The 2016 release includes a number of enhancements to the Vortex area-clearance strategy. Vortex gives the fastest safe metal removal from solid carbide tooling, in particular designs that give deeper cuts by using the full flute length as the cutting surface. It produces toolpaths with a controlled engagement angle and so maintains the optimum cutting conditions for the complete roughing cycle, giving faster machining and longer tool life. The ability has now been added to adjust and fine tune the non-cutting moves of 2.5D and 3D Vortex toolpaths, with options to retract the tool and/or to increase the feedrate. These options can be set individually, or can be combined to achieve an optimum toolpath, with a reduced cycle time. Other roughing improvements […]

Engineers at Oregon State University have developed a new “sustainable development methodology” to help address a social and regulatory demand for manufacturing processes that more effectively consider their economic, environmental and social impacts. The work was recently published in the Journal of Cleaner Production. It outlines a way to help designers and manufacturing engineers carefully consider all the ramifications of their design decisions, and to evaluate the possible different ways that a product could be built – before it ever hits the assembly line. “There’s a lot of demand by consumers, workers and companies who want to make progress on the sustainability of products and manufacturing processes,” said Karl Haapala, an associate professor in the OSU College of Engineering. “There’s usually more than one way to build a part or product,” he said. “With careful analysis we can identify ways to determine which approach may have the least environmental impact, lowest cost, least waste, or other advantages that make it preferable to a different approach.” This movement, researchers say, evolved more than 20 years ago from an international discussion at the United Nations Conference on Environment and Development, which raised concerns about the growing scarcity of water, depletion of non-renewable sources of energy, human health problems in the workplace, and other issues that can be linked to unsustainable production patterns in industry. The challenge, experts say, is how to consider the well-being of employees, customers, and the community, all while producing a quality product and staying economically competitive. It isn’t easy, and comprehensive models that assess all aspects of sustainability are almost nonexistent. “With current tools you can analyse various aspects of an operation one at a time, like the advantages of different materials, transportation modes, energy used, or other factors,” Haapala said. “It’s much more difficult to consider all […]

PIC CAP: Accessing data from the plant floor has never been easier than with Omron’s new remote desktop programs. By Harry Mulder Use of mobile devices, such as smart phones, to access data from the plant floor is becoming more and more commonplace. The fact that authorised users can now access such real time information from anywhere at any time, is highly attractive to many users. It’s also an integral part of the overall drive to increase efficiency. The technology behind this connectivity is remote desktop, which has been around for many years. This is where a “local” device (usually a computer but not necessarily so) runs its normal programs on the plant floor, as well as a server program. A remote client (again, not necessarily a computer) connects to this local server (usually via the internet) and displays identical information (i.e the local “desktop”) on is screen. The remote client effectively gains full control over the server as keystrokes and mouse actions from the client are mimicked on the local server, as if the user was entering them on the plant floor. Apart from supervisory systems, remote desktops are extensively used by help desks that provide remote assistance to computer users. There are many vendors supplying remote desktop programs: VNC (Virtual Network Computing), TeamViewer, Google Chrome (via plug-in), to name just a few. Even Windows versions as early as XP included in built support for a remote desktop. The technology is now very mature The sheer volume of packages in the market is a testament to how powerful this technique is and how important it is to those who use it. The technology is now very mature and usage is very high, across a wide range of industries. Recently, remote desktops have started to be used in the industrial realm. […]

Hovercraft’s which are also known as air-cushion vehicles or AVC can travel  over land, water, mud or ice and other surfaces. Unlike all the other vehicles we know, a Hovercraft does not touch the ground to get the lift, it uses blowers to produce a large volume of air below the hull that is slightly above atmospheric pressure. The thus generated air cushion makes the vehicle levitate in air making the journey smoother than any other vehicle. Surprisingly the first ever reference of such vehicle was done in 1716 by a Swedish scientist Emanuel Swedenborg and the air cushion design which is symbolic to these vehicles was patented by a British shipbuilder John Isaac Thornycroft in the year 1870. If you look up on the internet you will find a lot of DIY hovercraft projects which can be made with little to no experience and believe me it’s an extremely fascinating vehicle to make. Jan Bürstner is a Hovercraft enthusiast and was working on one such DIY project when he got inspired to make an Open Source 3D Printed Hovercraft. He designed all the parts of the hovercraft himself using the Autodesk’s Inventor 2013 software and has uploaded the same on Thingiverse. This allows anyone with a 3D printed to download the STL and create their own motorised hovercraft design. The current model of the 3D printed Hovercraft is the 3rd iteration and probably the most versatile model. In the earlier version of the Hovercraft Mr. Bürstner, experienced issues like the inability to control them outside of turning around their own axis, the inability to carry weight. The other major issue he faced was that the Vehicle was unable to recover from damages to the propeller caused by small pebbles. This was solved by adding a rubber base which could […]
