CNC rpm & feed

[Rewound]

yes so 7mm in the z and 2.8mm in its horizontal moves. 2.8mm is hefty , okay in a softwood, you might need to dial that down in anything harder.

what would be typical in a hard hardwood (lest say oak)

i normally run with 15 - 20 percent. the drop in material removal can be countered by using the both ways option in the tool path set up page. this will use both both climb and conventional and stops the tool retracting between moves, saves a bit of time.
what is it that youre making? just being nosey.


cheers

I use straight flute cutters (like router cutters) in my cnc when cutting ply or MDF.
They leave an excellent cut that I wasn’t able to achieve with up or down cutters which are primarily for metal cutting.

The problem with speeds and feeds is you have to know your machine. A chart is not the be all and end all.
