Hey Guys,
Doing some engraving on some .1 aluminum with a .0625 ball nose, I am going with .008 DOC with a .016 max which when I do that ,it goes around the entities twice -2 passes @ .008 = .016 all is good, however when I increase the max to .024 it should go around 3 times to get to that, but it goes around 4 times, any ideas why this does that. Does it not continue with the .008 DOC or somehow break the last 2 passes up into smaller DOC’s. Not really sure how deep it actually is cutting sort of hard to measure that, but I suppose I could try.
Also I am trying to get this down to production mode, how fast do I think I could actually do the engraving.
Currently using 15k @ .008 DOC - 25 feed -15 plunge. It’s a stiffer aluminum alloy. (.1" thick)
I try little increments, but sort of afraid to - sometimes I can start hearing a chatter so I back it off a little and increase the rpm’s --is that the general protocol? Chatter =slower speed - higher rpm’s? I have never went above 15 k yet -turned it up all the way last night and was surprised at how loud that gets, that baby is really moving -do any of you actually get up to those rpm’s? - I would definitely be afraid to try it.
depends on the software you’re using…
also assume floating point numbers are only almost accurate… you might hav a rounding error… if you’d set DOC to 0.0081 it would likely resolve 
Definitely a possibility.
If that isn’t it, the next question would be what forms you are engraving. Are the features such that the greater depth may require close, parallel passes to finish to width?
Hey Fenrus,
Thanks for the reply -I am using CC ver. 428 - I just thought it was weird why it was doing that, plus it takes up more time - CC does not allow 4 digits after the dec. can only do .008, I tried looking at the gcode but do not know what I am looking for or at for that matter. I guess I was just trying to understand the whole DOC thing - like if I set the max depth for let’s say .015 and set DOC to .008 how does it read this -one pass @ .008 and the other @ .007 or does it split the difference, same with max @ .025 and DOC @ .010 how will it read this? I was going about trying to have the max divisible equally by the DOC,or does it not matter?
enl_public - – Also thanks for the reply.
I have cut the same design using both figures @ .008 with max @ .016 it does 2 passes -@ .008 with max @ .024 it does 4 passes.
CC sort of leaves the balance to the lowest cut layer.
for cut quality, a thinner pass as the final is better…
