Unfortunately or fortunately depending on how you look at it the top and the bottom of the flag have the exact same dimensions from the cutout.
@Redlander what is the different in a rough and finishing pass on a contour cutout? I don’t believe I am understanding how that process works or what that looks like for a cutout.
Another consideration is Climb vs. Conventional Milling and tooling engagement — where possible avoid slotting and add geometry and cut as a pocket
and/or
and consider leaving a roughing clearance and taking a finishing pass.
Sorry, you’re probably not clear because I was not as well when explaining.
This actually is 2 separate cuts, the roughing pass is an offset pass leaving a small amount of stock for the finish pass. The intent is to minimize bit deflection, especially on smaller diameter bits.
That’s what I figured. Ok so that may be my next course of action. So make a roughing cutout then sneak up onto the dimension I need on the fly. I am going to try that two axis cut thing Will posted too.
Yes, not trying to make the project to take longer. Just trying to changing one step at a time to determine how it affects the outcome. This give you the piece of mind whether or not this was part of your initial issue of final dimensions.
Is there a reason you don’t use a larger diameter bit for the final cutout? This would help deflection issues.
Oh no it’s all good. I did offset the cut to compensate for the missing material and go a perfect cut on this flag. I am going to have to find some scrap or make a scrap piece to attempt the two axis cut Will was saying to do. I had to check those other posts he put up there too.
X (width) offset 0.0940
Y (height) offset 0.0625
Also I did notice on another project with a pocket that it was not cutting to the exact dimension I needed to fit something only on the square/rectangle shapes. The oval/rounded shape I needed came out perfect with the pocket I did for that.
@WillAdams is it possible or accurate to use my previous dimensions and the math equation to input the steps in the MDI since I have the measurements that are offset? Or does it have to be 100% like this and run the entire short axis with a piece and run the long axis?
You can use previous results, but I found that rounding errors were problematic and it was best to use the ideal and the actual measured distance only.
@WillAdams Good Morning, I was trying to verify when running the two cuts for each axis is it two separate cuts of different pieces or am I running both cuts on the same cutout to see any difference? Just trying to make sense of this before I execute, I am a visual guy so seeing it in action is more my cup of tea.
I usually did two cuts per axis — first one to measure, then do the steps/mm calculation, then make the cut again and verify that the math was right.
