Engraving/Cutting Acrylic with a CNC

Using a ShopBot, this training will demonstrate how to successfully engrave acrylic. Areas covered will include bit selection, feeds/speeds, toolpathing, types of material and cutting through the acrylic. Several projects will be cut and demonstrated.

thank you for a nice tutorial on bits and acrylic .

[@konturgestalter]

exactly what i needed... please more of these tutorials!

[@surginerc]

Very nice job on topic arrangement. Nice Delivery. I don't have a shopbot but I do have a pretty nice homemade machine. I also run Aspire software with some Vectrics add on's. I have purchased many bits from Think and Tinker. I like them. I will use your suggestions for the single flute O bit and the flat tip V's. Could you provide the name of material and source for the two color plastic used for the name badges in the video. Thanks again

You did not use tabs that i could see and yet you were able to do last pass on the items for good finish without it jumping all over the place, i did not see how you secured the acrylic so well, great info thanks

[@marouaneladjel1907]

think you for this

[@Stephen8454]

So single flute, up spiral would be best for final cutouts and have a good finish?

[@usd5000000]

the text on the Onsrud 65-025 mentions the downcut. Wouldn't that trap the chips in the cut?

Looks good, i make this with an Proxxon Micromot :)

Thank you for a good video, how did you smooth the sides of the acrylic?

[@shopbottools]

When using the appropriate bit, and feeds & speeds for profile cuts, smooth sides are achievable with ShopBot CNC machines. If you are referring to the edges, there are various methods to round edges of material, such as a round-over bit on a router table or various grits of sandpaper. Lots of methods. If you have any other questions about how the ShopBot CNC machine functions, please call or email any time! 888680-4466 or [e-mail]. Thanks!!!

[@Rhoude7695]

What feeds and speeds did you use on the demonstration cuts?

[@shopbottools]

Thanks for your question! There is a lot of variation with plastics and bits. We recommend using the bit manufacturers suggested settings or a great resource we commonly refer to is onsrud.com. If you have any specific project you are hoping to dial in on your ShopBot, I would recommend contacting our tech support at [e-mail]. Hope that info helps!
