    PVC Sheets

    Has anyone used PVC sheets with their CNC and do you have any advice on what not to do or how to best cut it?

    Just wondering,

    O flute or 2-flute up cut bit. Personally, I prefer deeper, slower passes to lighter, faster passes. RPMs should be relatively low at about 12000rpm.

    Otherwise, it cuts really easily. If it turns to dust, you're going too slowly. It should form decent chips.

    I also often use smaller cutters. If you do a final pass of about 1/4" of material, you'll pack the kerf and it will keep the material in place without needing tabs or only needing a few tabs.

    PVC is a common material cut on CNC machines, especially in the sign industry. I agree with Ross's recommendations for tooling, etc.

    Ross,
    Thanks for your insight! I have not cut any yet, but I will make a note of your advise for future work.

    James, I use a lot of PVC sheet material both 1/2" and 1/4" thick. I am not as big a fan of PVC as I am of Corian but it is less expensive and has some great qualities. Easy to machine, easy to laminate, easy to paint, etc. If your making a sign that requires a white background you can put vinyl on the surface and then paint. The vinyl cutting material sticks great is very robust and the result is a perfectly crisp machined area. Routed edges must be painted, the PVC machined edges tend to get dirty so they need a coating.

    Go to the dollar store, or anywhere, and buy spray static guard. Light spray on the sheet, turn on DC and mist a bit up inside. Tooling isnt really an issue. You can make do with anything.

    Hey, I just found these replies, for some reason I didn’t get the notifications, oh well.

    Thanks for the replies and advise, I am still sitting on these, I have a sheet of this to try, just not sure what I want to try with it and it has been over a month.

    I haven't even found a local place that sells pvc sheet material. I would like to try some but I can't find it locally. Everyone I've seen post about it says to use an O-flute and keep the RPMs in the 10K-12K range on the router.
    Thanks & Happy Wood Chips,

    Was going to say the same as Jim, HD I believe is Royal nationally but maybe not. Id imagine if your local branch doesnt have it on hand they can transfer it in. Last I checked it was actually competitive or a bit less than we could bring it in for. I think it was just a bit over/under $100 a sheet.
