All the cutting tools are from Aliexpress, very cheap.
Material Removal Rate 80 cm3/min, this is the maximum i can achieve with this 1.8 kW spindle . Probably more is possible with a 6 mm mill.
Regarding the surface finish i'm very satisfied, not super good but very good like a Carbonara pasta with cruncy guanciale.

  • Nice job, I'm doing similar. Your surface speed on Op1 is a bit too high though, around 603, you should be between 250 and 450 really for roughing aluminium with this style of cutter. From my calculations your op is drawing around 0.91kW. Seems to work pretty well but the spindle is bogging down a bit, the max torque of your spindle is probably lower down in the speed range so I would try figure out where it is and to optimise for that. Try increasing the chipload to something like 0.08mm/tooth and reducing the Vc (surface speed) you should be able to achieve very similar MRR whilst moving the spindle speed down to say, 18000rpm, where it has likely a lot more torque (I calculate 83cm3 MRR with these changes so you don't loose out, really. Where exactly your spindle has its greatest torque is not clear without the spec sheet but it is almost certainly not at full speed) Manufacturer should have a chart. A 6mm cutter with similar settings, and 0.07mm/tooth, should get you to around 63cm3/min with 0.72kW @20krpm. YG1 roughers are similar closer to 0.17mm/tooth but you'd need a bit more horsepower for that. A 6mm YG1 does 117cm3/min but needs 1.34kW. So an example would be (Vc 464, Fz 0.08mm/tooth, RPM 18500, Feed 4440, DOC 10, WOC 1.8 (23%) - MRR 80 to 83cm3/min (ish) - Power 0.91kW

    @johnharding9936@johnharding99366 ай бұрын

    • incidentally, for similar YG1 tools, you would normally go 1.5* diameter for the DOC and 50% Diameter radial WOC. I haven't calculated around that in your case with regards Horse Power and MRR but worth mentioning since they are quite similar tools in terms of geometry (I also use DLC tools like this too, they are good but every machine is different).
