Sescoi and partners demonstrate state of the art dental machining at free seminar

October 30, 2009 -  Sescoi, DentalWings, Agie Charmilles and Seco recently came together to run a free seminar demonstrating the latest advances in dental machining. Over a hundred participants, including delegates from many of France’s dental companies and prosthetic manufacturers attended the seminar hosted by the prestigious ENSAM School (Ecole Nationale Superieure d’Arts et Métiers) in Cluny, France.

Sescoi works regularly with ENSAM’s major R&D Center, and the latter’s support for the seminar is a significant endorsement of the state of the art technology presented. Delegates were able to follow every stage of prosthetics manufacturing, starting with scanning and manipulating a model in DentalWings software, and automatic programming of the high speed toolpath in WorkNC® Dental automatic CAM system followed up 5-axis machining of the prosthetic frameworks on a Mikron HSM 400U using Seco tooling.

By using the techniques proposed in the seminar, the machining of a dental framework in difficult to machine materials such as cobalt, titanium or zirconia can be completed in a few minutes, making it possible to produce between 150 and 260 parts per day while maintaining full traceability.

WorkNC Dental has been designed for ease of use. Tailored to the needs of dental professionals, the software enables the scanned information to be imported, orientated and nested ready for manufacture. Machining wizards guide the user through the programming, making it simple to produce collision free 5-axis toolpaths optimized for the special materials used in dentistry. The reliability of the software gives complete confidence in the results, while the wizards enable technicians not familiar with CNC machining to produce dental part easily and right first time.

Sescoi developed WorkNC Dental in close collaboration with dental technicians, adapting its ‘One Button’ CAM software to suit the needs of dental laboratories. Intelligent technology within the system selects tools and cutting strategies that have been specially adapted to high speed 5-axis machining, while considering the kinematics and limits of the machine tool to automatically produce highly accurate implants with an extremely fine surface finish. Further information and machining videos can be viewed on the Sescoi site.

Sescoi is also the software partner in the ambitious “Prodentic” dental prosthesis “open manufacturing” project. This 30 month, French government funded project is lead by the French UNPPD (Union Nationale Patronale des Prothesistes Dentaires) and AFNET, an association that promotes common standards in data exchange.
