Découpe de guitares personnalisées avec Cut3D

"Between the two of us we have a considerable amount of experience in the woodworking industry, including CNC machinery & the software involved. But the cost of industrial machinery and CADCAM software puts them out-of-reach to most small scale users. However, with the proliferation of affordable components and software, things have changed for the home user!"

With Gary's CNC experience they decided to take up the challenge of building their own cnc router. An impressive achievement on its own! This was to tailor the router and power fed drum sander to meet the specific requirements of the guitar project. The CNC router and sander were designed and built in Gary's workshop then transport 90 miles to Joel's workshop for Joel to take up the next phase of the operation. The CNC router is controlled using Mach3 software but as Gary and Joel explain the next tough task was to decide on the CAM software.« Nous avons commencé à explorer toutes les possibilités offertes par les machines à usage domestique et avons été ravis de découvrir les produits Vectric. Économiques, faciles à utiliser et parfaitement adaptés à tous nos besoins en usinage 2D et 3D. »

Création des guitares

Joel a d'abord modélisé les manches et les corps de guitare dans AutoCAD, puis les a exportés dans des formats de fichiers compatibles avec Cut3D et Cut2D. Après importation dans Cut3D, il a créé les trajectoires d'outils pour l'ébauche et la finition.

L'un des obstacles rencontrés était la production de pièces recto-verso précises. Pour ce faire, ils ont utilisé des gabarits de maintien de la matière, positionnés avec précision sur la table de la fraiseuse CNC grâce à des goujons et des pinces en acier.

La planche du gabarit est fixée par des goujons en aluminium qui assurent un positionnement précis de la matière pour le retournement et l'usinage des deux faces.With most new toolpath strategies, Joel machines them as a mock-up first to provide opportunity to make sure all tool paths are accomplishing their intended goal and avoiding potentially damaging situations such as running into (or through) clamps. Cut3D gave Joel the added reassurance that the CNC programs would perform as intended;

"One thing I especially appreciate and find to be very helpful about Vectric’s CAM software is the similarity of look and function between Cut 2D and 3D. When both 2D & 3D operations are run on the same part, the familiarity between programs really helps to prevent mistakes & mishaps."

After the machining was finished the guitar body and neck underwent detailed finishing, grain filler, 3 coats of sealer and sunburst finish on front. Joel then applied multiple coats of lacquer with sanding in between followed by a 4 week curing period & final polishing. All hardware & electronics was then installed ready for set-up for playing.Gary and Joel went on to say,"It's a long process but can't really be sidestepped with a high end custom built guitar!"

"This whole endeavour has been a real challenge and lots of fun for us even though some-what time consuming. Working with high dollar machines & software in an industrial environment certainly introduces you to the concepts of CNC. But building one is another challenge altogether. Close to a year to design & build the sander and CNC, but more than worth it to see the results."

Reviews of Joel’s guitars by both musicians & dealers alike have been very favourable. Fine instruments speak for themselves as sales have also proven.

Gary paid tribute to Vectric in helping him and his son achieve success;

"Our hats are off to the Vectric team for helping us reach our goal with such great software products!"
