Sheetmetal focus on Industry 4.0

“We’re aiming to get the very latest developments to customers as quickly as possible,” says product manager Olaf Körner. “Starting with Radan 2018 R1, customers needn’t ever be working with software that is more than six months old.”

The new release includes a number of items of new and enhanced functionality which focus specifically on the ‘engineering of parts process’. Developers are now working on separating Radan into two distinct aspects: traditionally creating NC code to drive CNC machines, and ‘engineering of parts’.

“Radan isn’t just a CAM system anymore,” says Mr Körner. “It plays an important role in ensuring sheetmetal manufacturers are best placed to run with Industry 4.0.”

An example of this is with Radmanager. The system now accepts feedback from the shopfloor regarding the cutting progress: “This improved connection between the shopfloor and logistics operations means the stock management and order processing functions can immediately update the stock control,” Mr Körner adds.

Radquote now looks at all aspects which impact on how much it costs to bend a part, such as how many bends are required, how many turns or flips the operation needs, and whether it needs a second operator, to provide an accurate cost calculation. In addition, it calculates the cost of an entire 3D assembly, rather than individual parts.

Mr Körner comments: “The user can see a full assembly tree and the total cost. These bending cost calculations – both for individual parts and complete assemblies – and the finegrain information flow between the shopfloor and Radmanager will assist considerably in facilitating the next generation of sheetmetal production as part of a connected factory infrastructure.”

Moving on to enhanced CAD/CAM functions, Radan 2018 R1 takes the increased popularity in automatic bending into consideration, with the specific innovation of optimising fingerstops. As part of a process of making fingerstops safer, it allows for improved part alignment in the press brake, and reduces the number of fingerstop movements required between bends.

In addition, an enhancement to the default views means designers can bring up a front view, side view, or isometric view instantly, in both Radbend and Radan 3D.

The profiling function benefits from six updates. Firstly, hatching, where laser users can now create fine marks to identify parts. Mr Körner says it can be any shape, such as a barcode design, text, or a number, and is simply ‘hatched’ on to the metal with the laser.

Enhanced flycutting, where the machine doesn’t stop during an entire operation; reduced cycle times, the lead-in placement for tagging has been optimised; additional support for automatic filleting, this means users have much greater control over where they are placed; Also, Radan developers have worked closely with plasma cutter manufacturers on additional support for cutting circular holes with higher accuracy on plasma CNC machines. And following the contours of a part when creating offcuts saves more of the material, reducing wastage even further.

Lastly, a new batch nesting system described as a ‘big performance upgrade’, which developers say could improve material usage by around 9% over a year. The use of a new algorithm provides a different approach to optimising a range of nests.

“The software now looks at the entire nest run and reduces the number of overall sheets instead of focusing on how full each individual sheet is,” says Mr Körner.

In other applications new controls have been added for producing offcuts on punch presses: “Some manufacturers like offcuts at the start of a program; others prefer them at the end. This enhancement means they can decide exactly when the offcut parts will be created.”

Finally, five individual small enhancements combine to improve Radan’s overall CAD/CAM usability.

Firstly, Radan 2018 R1 includes a more natural way of manoeuvring around the parts to select features; now there is just one click to update the stock list in nest projects; thirdly improvements to the process of changing programs from one machine tool to another have been introduced, whether switching between cutting technologies, or laser to laser but powered by a different gas.

Mr Körner explains: “It’s now easier to create a CNC program for one machine, and then for a different machine, and even using a different post processor.”

A fourth enhancement is the Teamviewer system, which support engineers use to gain remote access to a customer’s system for resolving issues.

Lastly, the optional analytics system helps Radan developers gather evidence of how customers use the software, so each new release can focus on the industry’s requirements.

“For example, it shows us which functions are used the most, and the sequence of clicks, which means we can look at optimising that in the future. It provides a tangible indication of where we should be looking to make enhancements, and is part of our ongoing philosophy of ensuring that the software is absolutely right for the customer, enabling them to take their businesses to the next level,” Mr Körner concludes.
