The project is a low cost CNC router that is simple to build and has a design that can be scaled up to meet the needs of most shops.
What will it do?
The CNC machine will be able to cut materials such as wood, foam, plexiglass, etc. to create 3D objects. These objects could be used as is or they could be used to create moulds for small scale production.
Who's done what beforehand?
There are several types of CNC machines out there ranging from professional grade to open source and DIY. One of the professional grade mahcines that many people know of is called the ShopBot.
Another is being produced by a company called Lasersaur which is an open source laser cutter.
The MTM Snap is a CNC Milling machine designed by some of the people at MIT's Center for Bits and Atoms. I plan on using the same circut boards as the MTM Snap as a part of my machine, but I will talk about that more later.
What materials and components will be required?
Currently, the design is still changing and evolving. Links to all materials will be posted once the design reaches a more solid state. The current version uses the following:
Tools Required
Where will the materals come from?
The materials will come from Home Depot and McMaster Carr Some other suppliers may be included later once the build has been finalized.
How much will it cost?
The goal for the budget is $250.
What parts and systems will be made?
Many of the parts will be fabricated and designed by me. The mounts for the Dremel tool will be made from 1/2" HDPE that will be milled and attached to the frame work. The framwork itself will be made from 1/2" MDF that has been glued together in some places and bolted together in others.
What processes will be used?
Several processes will be used in the design and creation of this machine.
what tasks need to be completed?
The design needs to be finalized and draftings need to made in order to have an accurate cut list.
Parts need to be order from McMaster Carr and any other suppliers that might be needed once the design is finished.
The circuit boards need to be milled, assembled, tested and programed.
The machine needs to be assembled and tested.
what questions need to be answered?
What size will the cutting area be?
What is the final cost?
How accurate is the machine?
What things could be approved upon in the design?
What went wrong?
What went right?
Will flame decal's make the machine go faster?
Will "Aperture Science" decals cause the machine to become sentient?
What is the schedule?
The schedule is:
How will it be evaluated
The machine will be evaluated based on its accuracy, speed and functionality.
