I found slotting is slow with anything.
The calculators don't take into account the force involved with slotting. If machining around the outside you only have say 1/4 of the tool side engaged (woc) at half tool depth (doc). (this is what the calculators are based on). When you slot you have double the tool engagement / double the force,
ergo- you have to HALVE the calculation figures. So: half the speed and 1/4 tool depth.
That's how I figure it anyway.
I always end up halving the HSMworks calculation.
It is what it is!!!.
Milling at home I go 1/4 shallow with a 3mm. I doc at 0.75mm, 2500rpm, 300mm/min. I'm limited by my rpm.Last edited by dazp1976; 18-01-2023 at 03:07 PM.
