Delcam adds more reverse engineering tools to PowerSHAPE Pro CAD system

30 03 2015

Delcam has added a number of new options for reverse engineering to its PowerSHAPE Pro software for the design of products and tooling. The 2015 R2 release of the software also includes improvements to speed up and simplify the editing of product designs to make them more suitable for manufacture.

By offering a combination of solid, surface and direct modelling, together with reverse engineering, PowerSHAPE Pro provides the most comprehensive range of design techniques available in a single CAD program. Having all the different technologies in the same package reduces the need to transfer data between multiple programs and so streamlines any product-development process that requires both reverse-engineering and CAD functionality.

PowerSHAPE Pro can connect directly to most scanning hardware to capture and display scan data in real time. The 2015 R2 version includes a new split-screen alignment option that makes it quicker and easier to combine multiple scans, taken, for example, from the opposite sides of a part. The new method also allows more accurate snapping of alignment points, giving greater accuracy in the resulting single CAD model.

PowerSHAPE Pro can be used to take cross-sections through the scan data to generate wireframe for the development of surface models. The wireframe can be simplified automatically into lines and arcs, reducing the number of points needed to describe the item and giving more precise geometry for the re-engineering of the model.

Another new option is the ability to morph a complete solid or surface model to a mesh. This can be used to compensate for spring-back when pressed parts are released from their tooling. Morphing can be used to update a nominal CAD model to match the part as it is made in reality or to modify the surfaces of the tool so that the part can be produced in the desired shape represented by the CAD model.

On the modelling side, analysis of models has been made easier as the Smart Feature Selector now displays the type and parameters of each feature interactively as the cursor is moved around the model.

In addition, the ability of the Smart Feature Selector to find, select and edit multiple similar features has been extended. Now, any number of items of the same type, not just similar features, can be edited in a single operation. For example, all the arcs within a model could be set to the same diameter or all the holes could be made the same depth.

Two enhancements have been made to the tools for the creation and editing of curves. Firstly, the Composite Curve tool has been more efficient so that it needs fewer clicks to create the curve, even when following fragmented edges. Secondly, the Re-point dialog now displays the deviation between the original curve and the new one, and it is also possible to re-point a curve to a known tolerance. This makes it even easier to create high-quality, smooth surfaces when re-engineering scan data or when remodelling an existing design to allow it to be manufactured.

Moulding Expo to become the meeting point for suppliers and buyers

27 03 2015

In cooperation with the new trade fair for tool, pattern and mould making, the BME Forum entitled „Purchasing of tools“ will be held at the same time in Stuttgart.

During the sixty years of its existence, the BME has become established as a technical association for purchasing and logistics in Germany,. The objective of the BME is to promote science, education, training and the exchange of experiences in all areas of materials management, purchasing and logistics.

During the sixty years of its existence, the BME has become established as a technical association for purchasing and logistics in Germany,. The objective of the BME is to promote science, education, training and the exchange of experiences in all areas of materials management, purchasing and logistics.

With the German Association for Materials Management, Purchasing and Logistics (BME) and its BME Forum entitled “Purchasing of tools”, Moulding Expo has found the perfect partner to achieve this goal. On 6 and 7 May 2015, the BME will stage a 2-day seminar concurrently with the trade fair in Stuttgart. This seminar is expected to attract more than 100 purchasing experts and managers who want to continue their training. Representatives from the areas of tool-dependent parts, tool purchasing, strategic purchasing, technical purchasing and commodity management tooling will be present in Stuttgart.

“The event will be highly beneficial to the participants,” said Professor Robert Fieten, the initiator of the Forum. “For example, the international procurement markets for tools, purchasing strategies or supplier selection will be examined during technical talks and discussions. However, the discussions will also focus on topics such as solid cost accounting and the conclusion of watertight contracts in order to ensure, for example, title to supplied tools. The BME has already successfully staged this Forum for six years. Buyers, i.e. our primary target group, tell me that there is nothing comparable. Some buyers therefore repeatedly attend the Forum. If that isn’t a complement!, said Professor Fieten, who has taken over responsibility for technical management of the Forum.
Staging the BME Forum during the first Moulding Expo in Stuttgart was a joint idea between Ralf Dürrwächter, Marketing Manager at the Association of German Tool and Mould Makers (VDWF), and Florian Niethammer, Project Manager for Moulding Expo at Messe Stuttgart. “We considered how we could reach the target group of buyers. It has never been possible before for buyers to combine advanced training with a very special trade fair tour in Stuttgart,” said Niethammer.

Exclusive tours of Moulding Expo are planned for participants in the BME Forum. “We are delighted that the German Engineering Federation (VDMA) will support us with its expertise during the tours of the trade fair,” said Niethammer. Alfred Graf Zedtwitz from the VDMA Tool Manufacturing Association will act as the tour leader at 15.30 on 6 May 2015. One day later, Ralf Dürrwächter and VDWF Vice Chairman Anton Schweiger will perform this task at 15.15. “We will collect the buyers in shuttle buses and then offer them an exclusive tour of the trade fair under expert guidance,” said Florian Niethammer.

The BME Forum will feature a number of first-class speakers, including Bettina Planegger from Daimler AG, Sinasi Oezen from Robert Bosch GmbH and Chris Groger from Carl Zeiss SMT GmbH. However, Professor Thomas Seul, President of the VDWF and Vice-Rector of Schmalkaldenwird University of Applied Sciences, will talk about German tool manufacturing as an innovation leader in global competition, developments on the market, the challenges in tool purchasing and the success strategies in this respect.

NCG CAM v14 is Officially Released

25 03 2015

NCG CAM Solutions Ltd, UK officially released NCG CAM v14. This major release includes a number of new features including UV surface machining, the ability to cover pockets, tools to align 3+2 axis, ability to quickly change the background colour, enhancements to translucency, 5-axis along curve machining, tool axis alignment curves for 5-axis along curve strategy as well as many enhancements including improved automation of the drilling in macros, the ability to copy and paste all of the strategy parameters and the ability to do rest finishing using a toroidal reference cutter.

5-Axis Along Curve Machining

5-Axis Along Curve Machining

In NCG CAM v14, UV surface machining is a new feature. This new feature will allow the user to select either a single surface, or a series of appropriate adjacent surfaces, and then to generate machining passes using the selected surfaces and the underlying UV direction parameterisation. This can be done by either a given number of passes, or a step-over distance.

This is not totally automated at this stage and requires the user to investigate the UV surface parameters with a view to swapping them to align them to a common machining direction. The UV directions are indicated by arrows.

New functionality to cover pockets is now available to allow the user to create planar patches from curves, machining passes, or remaining passes. Creating planar patches from the highest inaccessible passes in a Roughing Toolpath will cover and protect pockets of remaining stock, preventing smaller cutters falling into un-machined regions.

New tools are now available to help the user to align 3+2 Axis boundary planes.
Boundary alignment is a particular problem when there is not a planar surface with a suitable normal to orientate from.

The user is now able to quickly change the ‘Background Colour’ by either using the Drop-down Menu, or clicking the ‘Right’ button on the mouse. Previously 6 mouse clicks were needed to change it, via the Tools Options page.With the surfaces displayed in Shaded mode, it is now possible to change the translucency of all surfaces in a single operation. One use for this is to enable the user to see the holes inside the part when drilling.

A new feature has been added to the 5-axis module, 5-axis along curve machining. This will allow the cutter to follow a given curve, and the tool axis will remain normal to the underlying surfaces. One example of the use of this feature is to cut windows or trim profiles and edges into components made of composite materials.

Tool axis alignment curves for 5-Axis along curve strategy is a new feature that will allow the cutter to follow a Curve, then a second folder containing additional direction vectors will determine the tool axis. When machining, the tool axis will gradually tilt through these vectors, as it follows the curve.

Many other enhancements have also been added in NCG CAM v14, including improved automation to the drilling macros to make it possible to setup Macros to define drilling canned cycles and make them ‘Data Independent’ in the same way that milling operations can be setup as Boundary independent by selecting new Boundaries. Also the ability to Copy all the strategy parameters from the dialog page to the copy buffer, which will allow the user to be able to paste the copied parameters into a similar dialog in another NCG CAM session, reducing programming time and errors.

Successful launch of the platform INGRESS to ensure industry’s involvement in the European standardisation strategy

24 03 2015

The INGRESS (INdustry GRoup on European Standardisation Strategy) platform has been launched today by its 16 founding European industry associations. The multi-stakeholder platform aims at facilitating the representation and advocacy of industry interests groups on European standardisation policy matters, given that industry is the main contributor (funding 95% of standards’ development costs) and user of European standards.

blogIngress

Regulation EU 1025/2012 on European standardisation of 14 November 2012 grants the legal basis for the European Commission to request the three European standardisation organisations – CEN, CENELEC and ETSI – to develop standards which have the potential to support EU legislation and policies, provided that they are used by interested stakeholders. It also provides the status of observer to four categories of stakeholders in the regulatory Committee on Standards (CoS). The CoS is responsible for taking implementing decisions, such as on new standardisation requests, implementation guidance or discussions on the possible review of the Regulation. Unfortunately, industry’s participation in this Committee was not foreseen by the European regulator.

One of INGRESS’ primary objectives is to be recognised by the European Commission as a relevant stakeholder to participate, as an observer, in the Committee on Standards (CoS). As European standards are voluntarily used by companies to primarily support their needs, it is necessary to ensure that the European Commission’s standardisation requests will be equally attractive to industry experts who participate in the standards’ development process and, eventually, offer the best chances to a broader uptake of harmonised standards by companies.

“The European Commission’s standardisation requests could have a positive or negative impact on European industries, which are one of the main drivers of investment, growth and jobs within Europe. Harmonised standards have been one of the great success stories which helped Europe’s internal market to take off and develop. But these standards must always be relevant to manufacturing companies whose markets both in Europe and worldwide depend on them. Industrial policy, including standardisation policy, matters to keep or even reinforce competitive edge on advanced manufacturing sectors like, machine tools. Our industry is heavily contributing to the standardisation process. The issues of our sector are mainly addressed by CEN TC 143 (Machine Tools – Safety), however we would like to be involved also in earlier stages not only when the technical work starts,” said Filip Geerts, CECIMO Director General.

Delcam Professional Services offers free software for CADCAM process automation

21 03 2015

Delcam Professional Services is offering free Custom Software Core software to speed up and simplify the automation of repetitive operations in Delcam’s PowerSHAPE design and reverse engineering software, and PowerMILL CAM system.

The Custom Software Core was used to develop an automated manufacturing process for Yooshu’s custom-made sandals

Even though both PowerSHAPE and PowerMILL incorporate automatic routines as part of the software, many experienced users like to customise the software to automate further standard, repetitive operations specific to their application or product range. Typically, this is done by recording a sequence of operations as a macro that can be replayed when a similar calculation, or series of calculations, is required. For more complex operations, this can be a time-consuming process and can produce an intricate string of commands that is difficult for other users to understand or to edit.

The Custom Software Core is a library of middleware that allows users to develop code more intuitively than using macros when interfacing .NET applications to PowerSHAPE and/or PowerMILL. The use of an Object Oriented design, together with IntelliSense in Microsoft Visual Studio, means that the software engineer can discover the functionality available when interfacing with PowerSHAPE and/or PowerMILL more easily than recording a macro and pasting together a series of commands.

An additional benefit is that the number of lines of code in the customised application will be reduced, typically by at least 50% compared to using macro commands. Rather than using lengthy blocks of macro commands that are hard for other users to read and understand, the new application comprises easy-to-read function calls, each of which can encapsulate many lines of macro commands.

Using the Custom Software Core also makes it easier to upgrade any custom application from one version of PowerSHAPE or PowerMILL to a newer version. Any changes between software releases to the macro command for a particular operation can be handled by downloading a new version of the Custom Software Core. This new version will ensure that the application will continue to function as before, without any need to recreate macros.

The Custom Software Team within Delcam Professional Services used the Custom Software Core to develop an automated production method for Yooshu, a manufacturer of custom-made sandals. The Team, which combines software development and mechanical engineering skills, was able to develop a system that interfaces with a third-party foot scanner to obtain scan data from the customer’s feet. That data is then passed to PowerSHAPE to design the sandal, and then to PowerMILL to create and post-process the toolpaths used by a robot to cut the custom shape.

RoboJob offers flexible automation solutions

20 03 2015

RoboJob is a Belgian company which offers flexible automation solutions for the automated loading and unloading of CNC machines. With over 25 years’ in machining and over 40 years’ experience in machine building, RoboJob can rely on all the needed know-how to build extremely user-friendly standard solutions that can significantly increase gross margins in the machining industry.

Growing labor costs, declining volumes and shrinking margins. These are but a few of the challenges that many machining companies have had to face in recent years. In order to survive, many of these companies have had to find a way to cut costs, while improving the yield of their costly CNC machines. RoboJob now offers a solution that addresses all of these hot topics.
Helmut De Roovere, co-founder and CEO of Belgium-based RoboJob, understands very well which are the challenges that the machining industry is currently facing in the large majority of countries in Western Europe: “Just like many other countries in Western Europe, Germany has a very high cost of labor. But that is not the only cost that is impacting the profitability of machining companies: CNC machines are expensive and can be used much more efficiently. Machining companies need to make significant investments, but unfortunately, their profits are declining. Where the customers of these machining companies used to place large orders of 2.000, 1.000 or 500 individual production items, this has now gone down to 200, 100 or 50 items. Simply because keeping a stock costs money and globalized markets keep prices very competitive
“It’s an understandable trend from the customer’s perspective, but it does have a huge impact on the machining industry,” De Roovere continues. “If you know that the programming of a CNC-machine to produce 1 individual item takes exactly as much time as it does for 1.000 items, then something needs to be done to improve your flexibility and to manage your costs.”

RoboJob is the specialist in the automatic loading and unloading of CNC machines. RoboJob was founded in 2007 as a subsidiary of Aluro-Group NV for the purpose of autonomously dealing with returning the machining industry back to profitability, which has seen its margins decline year after year owing to the changed market situation.
The Turn-Assist and Mill-Assist are integrated solutions which enable the automatic loading and unloading of turning and milling machines. Both systems can be used for a wide range of dimensions (standard ø 5 to 400 mm) and weights (up until 700 kg).
