Using CNC in segmented bowl turning

[GrahamJ46]

I haven't been active recently in segmented bowl turning. About 2 months ago a I bought a desktop CNC and have been spending time getting up to speed with that. I would like to incorporate my CNC into other aspects of my hobby and that includes segmented bowl turning. I am wondering if anyone has done that and what they have done.

The woodclub I belong to has two CNC machines. Just started to use the CNC to cut segments for 90 segments per ring. First test ring came out great. The CNC machines the club has also has a lathe attachment for cutting on round objects. I might later try it to engrave some patterns on a bowl.

I think the accuracy of the CNC will be a plus when it comes to higher count segment per ring.

I have used my CNC machine to cut the pieces for two different platters. I have also used the CNC to build feature rings. I will see if I can find some pictures of those. Just a lot of fun to learn how to do more with the wood and machines that I have.

Thanks Larry. You have given me some things to think about.

That is really cool looking I just purchased my first cnc machine and I want to do things like that on my cnc and incorporate it with my segmented wood turnings if you could tell me how you did that on your router that would be great thanks

First, you draw a circle and divide the circle with the number you choose, draw an arc and then put some type of design into the arc. You use one of the arc pieces and cut that into some three quarter flat lumber. All the pieces should snap together, and if they do, then cut one half from two different colors of wood, glue the pieces together and turn on the lathe.

Hi
i have been using my CNC to cut out the segments. It has been very successful in doing this accurately. The only downside to doing this is there is more wood waste as you will need 3 times the width of your endmill in between each segment which at a minimum would be 3/8 of an inck. To me the accuracy is worth it.

I use my CNC a lot in my bowls. Vcarve logos in the bottom of bowls, Cut designs in segments most of the way through then fill with Epoxy, delight feature rings, etc.

I have tried cnc machine for segments but have found that my laser works far better. I typically make open and closed segment bowls with anywhere from16 to 48 segments per row and up to 3000 segments in the bowl. The segments are anywhere from 1/8 to 1/4" thick. I have a 70 watt laser but have used a 40 watt laser also. You will find you save a lot of material, sanding, and cutting slats by using a laser. The time savings is big. If interested I can also supply my method for very quickly creating the laser files for lightburn. cdmaxim46@gmail.com
