Tips for Cutting Foam on a CNC or CNC Machine

[@shyowl3453]

“Worth experimenting with” as someone looking to make a custom instrument case out of hard wood I can’t agree more, being able to test the design before spending 500$ or so on wood certainly is appealing to me

[@evolutionxone]

thanks for saying your feeds and speeds!

[@JasonPeltier]

yup, I just used 16k rpms and melted a glob onto my bit, lol

[@gianlucacuneo6096]

Thanks. Should the same tips be applied for expanded polystyrene?

[@iforce2d]

Most likely everybody guessed 'fish' because you had just told us a minute earlier :)

[@David-iq1kd]

Is climb or conventional milling preferred for cutting foam?

[@dmoss8928]

Where did you buy this at?

[@guzmanl80]

Cab I use this machine and method to cut floral wet foam?

[@Wwgoa]

Hello Lety! That’s not a product I’ve ever worked with, so I don’t know. Thanks!

[@fishskinleather933]

Hallo how i can buy this machine

[@rickd3361]

Could you share your v-carve settings? Having a hard time getting them correct. Thanks

[@Wwgoa]

Great question! I have forwarded your question to our experts. Please allow 1-2 business days for their response. We will post it here. Thanks!

Hi Rick, Speed and feed are provided at about 1:20 in the video. 10,000 rpm, just under 100 ipm feed rate. Paul Woodworkers Guild of America

Nice demonstration and good advice. I've got some great quality up-cut bits and such from Tinker and can't wait to try them out on the pink foam. I do a lot of wood 3D, and clay modeling/casting, so this gave me a bit of inspiration to try to venture into a new realm. I suppose the layer of each cut is relatively small compared to how you could on wood?

What is that product for coating foam to make it look smooth? Thanks

[@Wwgoa]

Hello, There’s a specific coating for foam that I use on CNC projects, but it doesn’t make it look smooth. It makes it look almost like stucco. You can see it here amzn.to/2nIqut8 Thanks, George Wood Workers Guild of America Video Membership

Hello! Is this EPS or actually Styrofoam? ..or XPS? I’d like to try so could you kindly tell me what exactly I’m looking for? Many thanks!

[@Wwgoa]

Great question! I'll submit your question to our experts and get back to you here.

[@mattbridges8384]

@@Wwgoa great! Thank you!

[@Wwgoa]

It is XPS. It's a building foam from Home Depot. Hope that helps!

[@mattbridges8384]

@@Wwgoa certainly does. Thank you!! We’ll give it a try. Just a bit worried about tearing - but we’ll see what occurs. Thanks again.

Thanks, I'm going try to cut some pink foam today. Do you have a good source for 3d models you could share?

[@Wwgoa]

I use VCarve Pro, and it came with a number of 3D models. You can also purchase models at Design and Make store.designandmake.com/ Thanks

[@1183newman]

You can cut out in foam and then lay on fibreglass to create a mould.

[@chaitanyamehta8786]

would you by any chance have more information or references on this? I am planning to create a fiberglass mould out of a CNC cut foam and I am running into a few challenges

[@michaelrudisill5148]

@@chaitanyamehta8786 Easy Composites Ltd youtube channel is fantastic. They also sell kits for wet laying parts. If you are in the states, Fiberglast has full kits to get started.

[@RCjunkie]

Next time just run a finish cut and see what you get I have done it

[@mikefarinella5268]

Sure is a lot quieter than cutting other materials.

Hello, I want to prototype an electric powered surfboard hull 72''x30'' on a bigger shopbot cnc router is it possible?

[@Wwgoa]

Hello, CNC routers are commonly used for prototyping so yes, you should be able to prototype a surfboard on a CNC machine. Hope this helps, George WoodWorkers Guild of America Video Membership

Thank you for your input.

Alrighty then....
