Delcam has added extra five-axis machining options to its Dentmill knowledge-based machining system for the manufacture of components for the dental industry.

The new functionality is intended to make it easier to program the manufacture of dental bars, implant bridges and customised abutments.

The previous options for the production of copings, bridges and abutments in ceramics and titanium have been enhanced.

The ability to use multi-threading technology has reduced calculation times for users with multi-processor computers.

Dentmill makes it easy for technicians with minimal experience of computer-aided manufacturing (CAM) to produce restorations using the latest machining technology, according to the company.

It is based on Delcam’s Powermill CAM system, which provides high-speed and five-axis machining.

This is claimed to allow the software to offer a wider range of machining strategies than is available in other dental CAM programs.

The use of five-axis machining helps to reduce material wastage, minimise hand finishing operations by removing undercut regions and to give more flexibility when machining difficult parts and materials such as hard-state Zirconia.

While Dentmill is often used alongside the company’s DentCAD computer-aided-design software, the program is completely ‘open’ and accepts data from any dental design system or scanner capable of exporting data in the STL format, which is used widely within the dental industry.

It can also output machining toolpaths to virtually any CNC machine.

The software features an interface with icons that can be recognised by dental technicians.

The process is completely automated, so no prior machining experience is required to produce high-quality components.

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.
