99% of Beginners Don’t Know This Easy CNC Trick!

I discovered this trick when making wholesale orders of 100 wooden trays. I remember dreading having to finish these trays because of all the sanding to remove these lines. Not only was I happy to not have to stand there sanding for hours, but I was also happy about the money that it put in my pocket by saving on labor costs.

In most CAM software, you would add radial stock to leave, in your case 0.03, then do a finishing pass, which cuts to final dimension.

I have been hobby cnc’ ing for a few years. To deal with these water lines, I use a very light full DOC finish pass as the last pass. I also run this full DOC finish pass at half of my regular cutting speed. I know, this isn’t optimizing the cnc machine or doing my chip load any favors, but it saves a ton of time. I am thinking, as I write this, that I should try a ball nose bit for contours as the lack of perpendicular cutting edges should eliminate the water lines. This would, of course, add a tool change to the mix and probably negate or even increase the overall cnc time.

Thanks for this! I'll be revising my files to incorporate this... great timing as I'm starting my holiday season work now!!

A best practice is to use a separate end mill for the finishing pass. This produces the best possible surface finish and lets you get the most value out of end mills used for roughing.

Love this idea, was also wondering what the sanding wheel is that you use in your drill press??

Thank you Andy for this tip. I knew this feature was in Vectric but I didn’t know where to find it or how to use it. This will help me with some craft show items I want to make for Christmas.

I have to put together my small cnc / laser knowledge is power
