Looking for some feedback. Just completed by first reasonably decent Vcarve Inlay. This was one of the things I was really interested in building my CNC for in the first place. I using Fusion 360 to design with.
I have some spots though where the seams aren’t as tight as I would like, especially around the letters. I trying to decide if the problem is in the male or female side of the inlay. I am thinking about on my next run leaving .5mm on the radial axis to see if it will make all the joints a little tighter. But I cant decide though because the gap isn’t consistent at all. Some places it seems to be on the Female piece while others the Male piece is the problem.
I would be happy to share toolpath settings but that is a lot to post, so I wanted to see if anyone had feedback before I did all that. I am wondering if my feeds and speeds might be more of the issue than the actual sizes.
I wonder if the tool mount is a little loose. It appears that a little flex in the router might be causing an overcut on one side and an undercut on the other.
Is this conventional milling or climb milling? I think the default for Fusion is conventional milling but climb milling is generally better.
Conventional milling causes the bit to deflect into the workpiece, removing slightly too much material. Climb milling causes the bit to deflect away from the workpiece, leaving behind a bit too much material. (Corners are a bit more complex.)
With climb milling and a second finishing pass, you can get a very precise finished piece, but with conventional milling you have to be a lot more careful with the feed rates and leaving stock behind explicitly in the toolpath.
When I started this project I used an old work table I had because it was free. The table itself does have some wiggle in the legs, but I felt like everything on top was attached securely. Do you think the table having a little shake would possibly cause this? It’s not a lot by any means, but it is not a rock solid base of a table either. I had planned on building an upscaled tabled once I got the basics figured out and working.
