Hi guys, can anyone tell me what I've done wrong here. First time cutting alloy and was a disaster as per the photos show. Machine is a stepcraft with a kress 800 spindle. 2mm 2 flute end mill. 1st cut was at 150mm/min at 12000rpm, 2nd at 70mm/min 10000rpm and 3rd at 50mm/min at various speeds from 10000 to about 14 or 15000rpm. As you can see the results are all very similar. Intial pass was set at 1mm step down then set it at .5mm. Had air blast on 2 attempts then just wd40 on the last. Using fusion 360 for software. Alloy is 6060. Hopefully I've included enough/correct information.
