A new version of the TubeWorks tube bending CAD/CAM software, which now provides tubular metal fabricators with powerful pre-production tools for laser cutting as well as tube bending, is available from the tube bending machine manufacturer Unison.

Developed by the UK-based software consultancy 3DCompound, TubeWorks is a specialist add-in module for the popular SolidWorks mechanical CAD package. By combining powerful visualisation capabilities with automatic code extraction and file generation, the software enables metal fabricators to substantially increase the productivity of their tube handling operations through optimal use of manufacturing data. The time that it takes to develop programs for CNC tube bending and laser tube cutting machines, for example, is typically reduced from hours to just minutes.

For tube bending, the software automatically extracts key manufacturing information such as bend angles and rotations from a native SolidWorks model or a common CAD file such as STEP, IGES or ParaSolid and creates the bend table for immediate use on a CNC bending machine, as well as the XYZ coordinates and a 2D drawing of the modelled tube.

Version 2.6 of TubeWorks extends this functionality significantly, by enabling users to 'unbend' the CAD models of bent tubes into flat (or straight) configurations containing full details of all holes and cut-outs, to provide the input data for laser tube cutting machines. Manually flattening a CAD model of a bent tube part requires specialist skills and is a notoriously time-consuming and potentially error-prone task. For example, flattening the model of a tube part that features five or six multi-plane bends and a couple of holes could take a designer several hours. In contrast, achieving this using TubeWorks merely involves a few mouse clicks and takes about 30 seconds.

As well as automating the extraction of manufacturing data, TubeWorks offers numerous functions to further help users minimise the pre-production design time of machine-based tube cutting and bending. These include automated centreline creation through tubular geometry (for both round and non-round profiles) and automated conversion of imported tube models into native SolidWorks models for CLR (centreline radius) modification.

Two new 'Power' functions are designed specifically to help users overcome a commonly encountered problem where SolidWorks does not recognise the tube face of an imported model as cylindrical, which makes centreline creation more time consuming. The Power Centreline function enables users to create a centreline sketch simply by clicking on appropriate features of the displayed model, while the Power Recreate function can be used to quickly reinstate model data from a centreline sketch.

The latest version of TubeWorks also now offers an automated Deduct Length function that enables users to shrink flattened tube configurations simply by specifying the required length change and the point at which it should be applied, to compensate for the elongation shown by their coordinate measuring machine (CMM). They can then immediately create a new YBC file for the bending machine and a new ParaSolid file for the laser tube cutting machine.

Alan Pickering, MD of Unison, points out, “TubeWorks has proved very popular with tube manipulation companies for speeding their quotation and production procedures. The addition of laser tube cutting functionality means that the software will now appeal to an even wider customer base, especially if they are seeking to reduce design-to-manufacturing times by handling all tube bending and cutting operations in-house.”

TubeWorks is a fully integrated add-in for the SolidWorks CAD package and is available exclusively from Unison. It eliminates the need for any additional software to generate manufacturing data for the design, development and production of tubular metal parts, while providing completely unfettered access to SolidWorks’ powerful design functions.

Unison has one of the most extensive portfolios of tube bending technology in the industry. As well as an exceptionally wide range of bending machines, handling systems and automated work cells, the company offers productivity enhancing software tools covering every aspect of tubular metal fabrication - from design and manufacture through to final inspection. Proprietary products include Unison’s powerful PC-based Unibend Office and Opt2Sim 3D simulation software for offline creation, test and validation of bending programs, as well as a unique calculator app for evaluating bending machine tooling that runs on Apple's iPhones, iPods and iPads.

Unison also distributes the VTube-STEP and VTube-LASER software produced by Advanced Tubular Technologies. These packages simplify the creation of production-ready programs for tube benders using CAD data; VTube-LASER extends this capability by allowing data from coordinate measuring machines to be used for bend correction or reverse engineering purposes.
