5 Axis CNC - PocketNC
Innhold
General
Bitraf will have available to members a PocketNC[1] 5-axis CNC capable of working on wood, plastic, wax, 6061 aluminum, 303 stainless steel and technically even G5 titanium and brass. It has a 115x128x90 work volume, a 50,000 RPM, capable of end mill shank sizes of .125 inch (3.175 mm) and soon 4mm shank. [1]
In order to use the PocketNC you must have taken a training course for the machine first. The first time you run a job, an experienced user of the machine must be present. To qualify for the PocketNC course we will require you to have completed the ShopBot course, learned to make 3D toolpaths in Fusion360, and successfully compleated at least 5 jobs on the Shopbot using Fusion360. Follow Bitraf's Meetup Group for these courses.
Kommersiell bruk
Dersom man gjør *kommersielle jobber* betaler man 350 NOK/time (+moms) for bruk av PocketNC. Kommersiell jobb betyr at du tjener penger på den. Normalt sett enten en jobb hvor du får betalt for å lage noe eller hvis gjør produksjon av noe du selger eller tjener penger på på andre måter. Dette bidrar til kostnadene ved vedlikehold, samt for å ikke urettferdig konkurrere med andre som leverer CNC tjenester, og at ikke bruken blir monopolisert av noen enkelte som driver gratis masseproduksjon.
Kommersiell bruk betales normalt i Bitmart med kort. Legg inn epost så får du kvittering på epost. Dersom du trenger en faktura, kan du istedet skrive en epost til "kasserer@bitraf.no" hvor du spesifiser antall timer bruk og dato.

Software
Fusion 360
Fusion 360 should be used for designing models and building toolpaths (GCode). PocketNC has made available 3D STEP files for the rotary table and common end mills which helps with simulation and part alignment within the design space.
