    Probably to few of us that what to use that kind of feature.

    Eric,
    Version 6 has many nice things. I think it is worth it.
    The software does the tiling, I just tested it, but the tile has an overlap of whatever size you specify. It does not generate the scarf information in the toolpath. One has to go do this manually. I don’t know how as you don’t have access to the tiles until the toolpath is created. Maybe first cut the parts and then toolup and do the scarfs. Just make sure that tiles are all the same size.

    Hey Eric,
    Sorry to hear about the problems with Irene. I have been watching the media – not a good thing at all. They seem to be getting more severe all the time.

    I have VCarvePro 6 but it does not have the scarf joint feature. I would very much like to do that. It can break the tool path up into tiles but no joint involved. Pity, I will have to keep doing it manually.

    Eric,
    Do you have a web link for the CAM software (Partworks)?

    Mike,
    Depending on the material type a different cutter will be used. Normally the guys charge for machine time so the cutter size is very important. I use 12mm or 0.5″ special cutters for laminated materials. The rule of thumb is to cut no more than 80% of the diameter in one cut. Again this is dependent on the cutter type. Normal straight fluted cutters, no mare that 50%. I.e. if you use a 8mm cutter you would do 4mm passes.
    Next, if the machine has a vacuum bed for holding the job, you can get pretty close between the parts. If not, you want to make sure that the parts don’t come out before the job is done. For this you include what we call tabs. It is a piece of material left uncut on the outer edge of all parts. You decide the spacing but what it does is to keep the parts stuck to the material until you manually break the tabs and release the parts. If you cut this way, you need more flesh between the parts.

    Dida,
    For model building, that project is just fine. Please feel free to contact me if you need any help.

    Dida,
    These plans are for a very small machine. I don’t know how many boat parts you would be able to cut on that. If you want to build a larger machine to make hull parts etc I will help you with the right stuff. I have plans for an easy to build large machine that I used in production of large panels.
    It just depends on what you intend to do with the CNC machine.

    Mike,contact me at marius at mastercut dot co dot za.

    Yes you can just give the CNC shop your dxf file with some instructions. Normally this kind of cutting is what we call 2D cutting. They will cut on the dxf lines for a certain depth or for the thickness of the material.

    CAM software comes in various shapes and sizes. Some are free but the better ones you have to buy. Mostly very expensive for the better ones. The CNC shop will own the best CAM software for their machines. I have several packages. It depends on the type of job as to which one I will use.

    Dida,
    As CNC Machines are my business, I will reply quickly.
    DXF is the acronym for “data transfer file”. It is widely used to make CAD or other information available to any other program.
    CAM is the acronym for “computer assisted machining”. So by taking the dxf file you can create a program for the CNC machine to cut the material automatically.
    CNC is the acronym for “computerized numeric control”.

    In short then, take the CAD design of the frames (dxf), load them into a CAM package in order to tell the machine how to cut them, and then load them on the CNC machine to cut.

    Sorry for the delay, I changed email but never did it on this forum.

    You can use a program called ABViewer. This is for dxf files. After that you can use them in almost any CAD software. Depends on what you want to achieve.

    You enter the stations at their respective locations and then you do a 2D dxf export with the create individual files option clicked.
