Greetings, happy to be up and running parts with the X carve but am having a strange anomaly in the cut. For some reason even though I have double checked the art and it looks good in easel, it is carving one side wider on the left side of the top of the skull than the right. See pics.
ANy help appreciated
I am using a 1/16 2 flute bit from Lakeshore
cut rate is 7.1 ipm
Cutting on the inside of the logo
Dewalt speed approx 21559 rpm (number 4)
Smartest thing to do is cut that again rotated 90 and 180 and 270 degrees. I think you will see your machine needs adjustment. It could be your Easel drawing (but I seriously doubt it). Once you get it dailed in:
(IMHO) That is incredibly slow feed rate for aluminum and the spindle is too fast… Turn your spindle down to 12-15K (probably 1). If you have have a stock machine:
For the 1/8" bit: I would decrease the DOC to .002 and up your cut rate to 40 inches per minute
For the 1/16" bit: DOC to .001 and cut rate to 25 inches per minute. Once you get good results, you can try to push this to .002".
If you do not have forced air blowing on that, then, I would be hitting it with wd40 too, as it cuts and get those chips out of there. I bet there is aluminum paste gunk welding to the cut, to the bit, etc.
