Profile cut out

[zaxis4]

Does anyone know what causes a layered look or kind of banding when cutting out of thick stock (wood). I am cutting out of cherry with a .125 upcut end mill each depth pass shows up as a line just enough to have to sand out. The bit is an Amana 46125 that is new. Could it be deflection??

Could be deflection. Could be a tramming issue. Does it show up on cuts on both the X and Y axis? -or just one of them.

If they only show up on cuts along a single axis and not the other, then you probably need to tram your spindle.

Otherwise, I'm not sure what the issue is.

In further reading about the final pass allowance, "witness marks" are mentioned and reversing on the last pass as well as taking a few thousands off is the fix for this. This phenom must be somewhat normal the way the last pass option is described....not sure I am going to try it on the next cutout.

That is the ticket!! Final pass clean up solves the issue.

Consider checking out the Monport laser for its user-friendly design, high quality, and affordability. Unfortunately, I can't access external websites like monportlaser.com/collections/co2-laser-engravers/products/monport-40w-lightburn-ready-12-x-8-co2-laser-engraver-cutter-with-fda-approval?sca_ref=5031521.ka374VZjm3 As for the issue with the layered look or banding when cutting thick stock (wood) with your Amana 46125 end mill, it could be due to deflection, tool wear, or machine settings. Try reducing the depth of cut, checking for tool wear, and adjusting machine settings for better results. If the issue persists, consider consulting the CNC machine or end mill manufacturer for further guidance.
