CNC Cutters advice please|Forum|WOOD DESIGNER

Hi Elliot,

I'd be interested to hear what cutters you're using and the optimal rotation and feed rate you found for different materials.

cheers,

Hi Elliot,

If your cutters are burning your either your RPM is too fast or the feed rate is too slow.

You should be able to cut 18mm MDF in 1 or 2 passes plus onion skin. 

Aim at getting chips and not dust.

You can get approximate RPM and feed rates either from the cutter supplier or using a chip calculator.

But you'll probably have to make some test runs to optimise.

Here's a link to and article that might interest you:

I've attached the Excel sheet chip calculator.

another chip load calculator here:

MDF is quite and abrasive material so you will have to test various cutter types and set ups to get best results.

Here's a woodweb forum discussion on this problem:

Hope this is helpful.

All the best,

Ness
