Radan 2018 R1 focuses On CAD/CAM, and Industry 4.0

As well as taking “a major step forward” with technology geared towards helping sheet metal manufacturers implement Industry 4.0 smart factories in its latest version, Radan will now be issuing two new releases a year.

“We’re aiming to get the very latest developments to customers as quickly as possible,” says Radan’s 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” processes. 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 any more. It plays an important role in ensuring sheet metal manufacturers are best placed to run with Industry 4.0.” An example of this is with Radmanager. The system now accepts feedback from the shop floor regarding the cutting progress. “This improved connection between the shop floor and logistics operations means the stock management and order processing functions can immediately update the stock control.” 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. “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 sheet metal production as part of a connected factory infrastructure.”

Moving on to enhanced CAD/CAM functions, Radan 2018 R1 takes the increasing 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. Enhanced flycutting, where the machine doesn’t stop during an entire operation, reduces cycle times; the lead-in placement for tagging has been optimised; additional support for automatic filleting means users have much greater control over where they are placed…they can be switched on for one part and off for another, and whether they are on internal or external corners. 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. A new batch nesting system is described as a “big performance upgrade,” which forecasts show could improve material usage by around nine percent over a year. A new algorithm provides a different approach to optimising a range of nests. New controls have been added for producing offcuts on punch presses.
Finally, five individual small enhancements combine to improve Radan’s overall CAD/CAM usability:
•    Radan 2018 R1 includes a more natural way of manoeuvring around the parts to select features.
•    Just one click to update the stock list in nest projects.
•    Improvements to the process of changing programs from one machine tool to another, whether switching between cutting technologies, or laser to laser but powered by a different gas.
•    The Teamviewer system, which support engineers use to gain remote access to a customer’s system for resolving issues, is built into the latest software release.
•    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.

Vero Waveform Saves Tool Costs of Over £100 Per Part

Trials carried out with Seco Tools show that Vero Software’s powerful, game-changing Waveform Roughing Strategy can save nearly £130,000 on cutting tool costs for 1,000 parts, compared with conventional machining strategies.

The results came from trials using a Seco 20mm tool, cutting components from EN24 steel. Vero’s Strategic Partnership Manager, Wesley Tonks, says: “Tool life is dependent on how the tool is implemented within the machining process. We always state the increase in material removal rates when utilising the Waveform strategy instead of traditional machining methods”. However. there are additional massive financial benefits to be realised with the reduction in tooling costs.

“Because the Waveform strategy, while utilising the full flute length of the tool, gives improved stability, less stress, and improved swarf evacuation, ensuring even wear, a financially beneficial regrind programme can be introduced.”

And Waveform increases the tool life before each regrind is required. For example, during the trial, the £357 tool was reground four times, as well as there being 275 minutes between each regrind. This meant the total tool life going from 60 minutes with conventional machining, to 1,100 minutes with Waveform. Waveform also speeded up the operation, reducing the cycle time from 22.5 minutes to 7.5 minutes.

On a production run of 1,000 parts, the tool costs using conventional machining were £133,875 – falling to just £4,125 with Waveform – a saving of £129.750. Even cutting Titanium, Waveform extends tool life from 150 minutes to 360, with three regrinds, delivering savings of £42,910 when cutting 1,000 components.

Waveform was originally part of Vero Software’s Edgecam milling package, but has recently been adapted for turning…and is now also included in Alphacam, WorkNC and Surfcam.  As well as the extensive savings brought about by the constant chip load, Waveform also delivers considerably improved material removal rates, minimum tool vibration, deeper cuts, and increased speeds and feed rates, with a smooth toolpath which avoids sharp changes in direction, maintaining the machine’s velocity.

The toolpath is automatically adjusted to compensate for load fluctuations. Tool engagement is decreased in concave areas and stepover adjusted between passes to maintain the desired engagement. In convex areas, the opposite happens – as the material falls away the toolpath stepover is increased to maintain the tool engagement.

“To conclude, it is very typical to have smaller batch sizes but to realise savings the whole manufacturing operation needs to be appreciated,” says Wesley Tonks. “Looking at where particular tools are being used and consumed across many operations and machines will expose manufacturing production facilities to increased savings.”

Tombstone Module: One Of 50 Edgecam Updates

 The new 2017 release of Edgecam introduces a Tombstone module for assembling pre-existing parts on a defined mounting device.

blogmachine-configuration-linear-turret-and-sliding-material

A simple dialog window enables users to add pre-machined part files, specifying the positions they are to be mounted on a tombstone or other multi-component work-holding device. Once they are assembled, Edgecam automatically merges and rationalises all machining sequences by tool or index position and optimising the NC output into sub-routines. Edgecam Brand Manager John Buehler says: “This new feature offers huge time savings, as users no longer have to manually carry out the load, insert, merge and rationalize commands.”

There are just under 50 items of new and enhanced functionality in Edgecam 2017 R1, covering turning, milling, wire EDM, machine configurations, and user experience.

Amongst the updates, Edgecam’s Code Wizard includes two highly significant enhancements in terms of machine tool configurations for lathes. When specifying Turret Type, the code wizard now supports Linear configuration. On this type of turret tools are mounted in a linear fashion, across either the X, Y or Z axis. “This arrangement is largely used on Swiss-type machines, but in other normal configurations, too.”

Radially and axial mounted tools are also supported, in both single and multiple spindle environments.

Another new feature is a sliding spindle or material, providing support for machines where the tool is static but the material slides in and out of the chuck or collet. “Again, this is similar to Swiss-type machines,” says John Buehler.

Having supported probing on mills for many years, the latest release of Edgecam introduces the same technology in the turning and mill-turn environment. Renishaw and m & h probing systems are supported, as well as a new Probe category in the Toolstore. Users can choose from a list of seven command cycles, all fully supported in the machine simulator.

Several background enhancements not only improve picking/highlighting when working with solid files, but show improvements in speed and part file manipulation. These enhancements come about through improvements to Edgecam’s own internal engine, and by upgrading the OpenGL 3.3 technology.

The Update Fixture command has been enhanced to include optimised Indexing moves. “Previously, users had to pick a safe Index position for the whole sequence. Edgecam 2017 R1 removes this limitation, by automatically checking and correcting all Index Moves against stock and fixtures.”

Additional updates have been made to the Rough Groove cycle…this time to include canned cycle support, through a Canned Cycle check-box. A further enhancement in the Turning environment sees most Turning Cam dialogs upgraded featuring pictures to define cycle functionality, which John Buehler says will be especially useful to new and infrequent users.

Users working with multiple components will gain significant benefits from two new features in the Insert Component command. “It’s now possible to insert separate machining sequences – whereas in the past all sequences had to be inserted, which, in certain set-ups, wasn’t necessary.” Also, CPL datum can now be selected from a simple drop-down menu.

The new release includes three specific enhancements for wire users – transformation, Fanuc technology, and Wireframe Feature Finder. The previous of Edgecam introduced the Transform command, and this latest version evolves the Translate function within that, by adding two further significant time saving Transform commands: Rotate and Mirror, which also supports sub-routine output. And the new software also supports Fanuc α-C600Ia in the Technology tables.

The new Wireframe Feature finder command caters specifically for users working with 2D/3D wireframe CAD data. It removes the need to rely on Linked and Taper Profile commands, making it easier to work with intricate profile shapes.

The need to create stock to run the Machine Simulator has now been removed. A new command in the Preferences section now defaults Edgecam to create stock automatically. When the system detects the absence of stock, it copies the component solid model, converting it to stock. “This offers significant time savings where the user simply wants to check a finishing cycle, or is working with Probing cycles.”

Three new pieces of functionality have been added to the Profiling cycle. Cut Increment Stand Off, under the Links tab, gives control of the cutter’s position during passes. The Helical function now has a Supress Helical Clean Up Pass Offset option in the Multiple Passes function determines the order of cuts. The Multiple Passes function now offers Cut By Offset, which allows the user to determine the manner in which the toolpath is distributed.

Numerous new features have been added to the Workflow and Planning Board automated machining commands, leading to toolpaths being generated faster. Strategies are now applied to both Main and Sub Spindles in the Turning environment, instead of only in Main, meaning the strategies now support the Spindle Set-Up command by transferring the workpiece from the Main to the Sub Spindle. And the introduction of Hole Finish Method in the Options dialog now allows Reaming to be specified as a method of finishing a hole feature by checking the hole’s finish attribute. A new Use Current Tool check-box in the Machine Feature option can force the strategy to use the current turning tool or milling cutter.

Session details have been added to Setup Browser and Rotational Handle on Dynamic CPL Marker within the Turning environment. John Buehler says these are ease of use enhancements. “Specifically with turning, users will notice that the CPL Marker looks simpler by just displaying the X and Z markers. The new marker can be used to dynamically rotate, pan and translate the component. The Set-Up window has been split into two distinct panels – Session, which displays environment and material information, and Set-Up dealing with datum and positioning. And when loading multiple parts the Set-Up window will individualise each solid model and automatically add a new CPL datum, meaning each model can be scrutinised individually, and datum altered.

There is no longer any need to program Rapid To Toolchange and Rapid To Home commands when working with turning and mill-turn machines, as this can now be set as the default.

And finally, a new option of Mating Location has been added when CPLs are created, signifying a machining sequence datum…along with Machine Location when inserting components. The main benefit of this is to filter out unnecessary CPL datum while using the Insert command, Index command or the new Tombstone function.
