Investing in a Romer Cimcore portable coordinate measuring arm with Delcam’s Powerinspect inspection software has proved to be a big time saver for Rayco Manufacturing.

‘It saves us many hours compared to the manual way most fabrication shops check their work,’ said Roger Timmons, quality assurance engineer.

‘We get more information about our production faster, so we can make adjustments quickly and accurately,’ he added.

Rayco Manufacturing, based in Wooster, Ohio, was established in 1978 to build equipment for the tree and landscape industry.

Most of the work at the company involves cutting and welding steel to form machine structures.

As Rayco grew and its product ranges expanded, the company decided that it needed to further improve the consistency of its steel fabrications and assure quality from the first laser cut through to the completed fabrication.

According to Timmons, an important advantage of Powerinspect is that the software has a simple user interface.

‘The learning curve was very short, which allowed us to get the most from the measuring arm in the shortest possible time,’ he said.

‘I can import CAD models directly into Powerinspect and overlay what we measure, which reveals immediately where any discrepancies may be.

‘Five minutes with Powerinspect saves an hour out on the assembly floor.

‘We can make adjustments before the components get into the assembly flow,’ he added.

For example, the software showed that the run-out on some of the feed wheels used on its chippers was not acceptable.

Detecting the situation prior to assembly saved the one and a half to two hours it would take to remove and replace an inaccurate feed wheel.

In another example, the frame for one of the machines was exhibiting a twist during assembly.

‘We measured it during welding and found that the fixture needed correction,’ said Timmons.

‘We also use the system for troubleshooting out on the assembly floor to determine why a part may not be fitting perfectly, so future parts can be corrected before they go to assembly.

‘We can do this in about 10 minutes, a time saving of up to 1,000 per cent compared to any manual method,’ he added.

Rayco did not have a dedicated quality department until about three years ago, and today it inspects critical parts and all fixtures on a regular basis.

Delcam supplies software and services that help manufacturing companies to maximise their profitability by increasing productivity, improving quality and reducing lead times. The company is the world's largest specialist supplier of computer-aided machining software, with its PowerMILL, FeatureCAM, Partmaker and ArtCAM programs making up the most comprehensive range of CAM systems from any developer.

This broad selection allows Delcam to offer a CAM system capable of machining virtually any product, in any material on any type of equipment. Delcam also develops product design, tooling design and quality control programs. The unique Tribrid Modelling approach to design incorporates solid modelling, surface modelling and triangle modelling in a single program, enabling complete design and reverse engineering projects to be undertaken without transferring data between software.

Delcam's Powerinspect offers fast, reliable comparison of parts, prototypes and tooling against CAD data on all types of inspection equipment and even on machine tools. This versatility has made it the world's leading hardware-independent inspection software. Related programs are available for checking machine tool set-up and part location. Delcam software is used in over 80 countries worldwide by around 40,000 organisations, from large multi-nationals to small sub-contractors, in industries including aerospace, automotive, dental, engineering, footwear, medical and toolmaking.
