RESULT !

Had a bit of time off work today so out in the shop :)

The new cut parameters seem to be perfect so far, the 5mm roughing cuts seem a bit off as i was seeing some chip-welding to the sides of the cut, this was at 2.5mmDOC an 1350mm/min @ 24000rpm, this was with coolant as well so its a bit wrong somewhere there, not sure if too much rpm, too much feed or something else, manuf states max rpm is 12000 so maybe i need to retune at that speed?

I made several alterations to the CAM and CAD by way of pre-finishing the sharp corners with the 2mm tool - this works great, then the final pass with the 2mm at 24000rpm 5mm DOC, 0.1mm WOC and 244mm/min feed spat out lovely little shards of swarf and not dust. Surface finish is now 100% quality.

The CAD/CAM changes also reduced my part time from 45mins+ to 20mins which is a considerable change, that includes tool change but not plate setting and bed clean-up.

Pictures later.
