Sorta ready for Xmas
Sorta ready for Xmas
The profiles were cut using 1/8in 2 flute end mills, using a feed rate of 1000 mm/min @ 12,000 rpm and 0.75mm DOC, while for the pockets I used a 18mm 2 flute router bit with a feed rate of 750mm/min @ 12,000 rpm and a 0.5mm DOC. I'm using the Inventables 300W spindle which I find pretty nice, but I want more power!!
One problem I ran into was chattering and a rough finish when cutting out the main body with a 30mm long 1/8 end mill (1000 mm/min feed rate & 0.75mm DOC) does any one have any recommendations for feeds and speeds for this situation?
cheers,

Do you have the link handy for where you bought the 18mm router bit? I've been using a 10mm end mill for roughing out things, and haven't yet seen larger stuff that's affordable, which will fit in my spindle. 18mm sounds like it would clear stuff fairly quickly.ijv wrote:...

There are "feeds and speeds" calculators around (including free), which might help:ijv wrote:... does any one have any recommendations for feeds and speeds for this situation?

Thanks, my daughters think they look nice as well, but that didn't stop them from decorating them with stickers and the like.They look nice

I'm in Australia, I got the bit at the local big box hardware store.Do you have the link handy for where you bought the 18mm router bit?

Thanks, that makes tonnes of sense. I should be able to find something locally or on Amazon along those lines.ijv wrote:I'm in Australia, I got the bit at the local big box hardware store.
