Hi All,
As you can see the engraving isn’t smooth and has lot of marks left by the end mill. My question is
how to improve the engraving quality to get a much smoother result?
Details:
Nomad Pro
Brass 1.5mm thick
Max depth of engraving: 0.2mm
2mm ball nose carbide end mill
Dept per pass: 0.05mm
Plunge rate: 600
Feed rate 1000mm/min
RPM 20000
Thank you all in advance.

My first instinct would be to slow down the feedrate.
Are these single pass cuts, or pockets?
My 2nd instinct would be to use a different software that lets you climb cut.
They’re contour tool paths as in CC.
What kind of software would you recommend?
Gunter
I assume contour toolpath, on an open contour. You end up with cutting with both sides of the bit at the same time, with each side fighting each other. I wonder if a “spring” pass would help?
I use NX for anything I can’t get CC to do well. Way out of most of our price range, but I work for Siemens.
Can you share the .c2d file? I have a couple ideas how we might be able to get it to climb cut. But it will depend on the width of the letters & the tool.
Sorry not sure what you mean by open contour… depth increments set at 0.5mm per pass up to 0.2mm
Gunter
I think Open Contour means a contour (No Offset) operation on an open vector. (The centerline of each letter stroke). I assumed you were doing an inside contour on a closed vector? Outside on the center portions of letters.
Many times you can VASTLY improve surface finish with a finishing pass. Make the last pass around 0.02mm and see if that helps.
Open vector is what I meant, You’re lettering looks like single line fronts.
I used stick fonts and no offset so the tool just followed the font lines in depth increments.
Many thanks,
Gunter
Great, I’ll try that!
Thank you!
