Realigning a work piece

The first project I started with my SO3 has been with aluminum to make a part for a motorcycle. I've run into quite a few problems getting feedrates and RPM's just right to make machining as quick as possible. I get half way through the machining and either the end mill gums up or the router doesn't...

Re: Fusion 360

Fusion 360 has a post processor for carbide motion. Under Post Configuration select carbide3d.cps and leave all other setting at default. As far as using carbide motion, there's quite a bit to be desired yet in the software.

Re: Aluminum slot milling

A couple other options are try turning on helical in the slotting tab in 360 this would put less of the tool in contact at the cutting area. The other option is create an outline 1.5- 2X the width of you tool from the outside of the part 1/2 or 2/3 the thickness of your part do a 2D adaptive on it....

Re: Aluminum slot milling

As gummy as aluminum is my gut says follow Will's advice with the wider slot and I would give a 2 flute end mill a shot. If you need really good surface finish. Leave a bit of Aluminium at the bottom(one or 2 passes) and a couple of thousands on the part and do a cleanup pass with the three flute. ...

Aluminum slot milling

So I had gotten quite far milling this part out of 6061-T6 bar stock. Was at first using a 4 flute carbide with AlTiN coating. Obviously gummed up without lubricant quite easily. Switch to a 3 flute from Lakeshore Carbide with ZrN coating. Chatter was less but still there. Milled fine dry until it g...

Re: Milling stock to required thickness.

Those numbers were just unrelated figures since I didn't have the actual numbers handy.

Milling stock to required thickness.

Getting ready to mill my first project on my SO3. That being said I have a question on milling metal stock. My part will be milled out of aluminum but the stock I will get will be thicker than the finished piece. So how would I go about milling the piece to the required thickness so I could then run...

Good milling bits?

So I just received my SO3 a week ago and have everything just about setup. I want to try out PCB milling but I'm not quite sure what kind of bits to use. So are these an ok set to use? http://www.amazon.com/gp/product/B012V9HP2S?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A197AK0BCWKF8C Are they...

Re: Able to mill this?

I think you could do the whole thing out of a solid piece on the S3. It would take a while. The groove/ring could be done with a T-slot mill or something similar. What you want is this: http://mindworks.shoutwiki.com/wiki/File:Convex_Radius_End_Mill.jpg If all you need on the back side is a chamfer...

Re: Able to mill this?

To cut that ring...im not sure if thats a detent, hose clamp groove or what...but youll need a special bit and toolpath for that. Heres an example of router bits that have a similar profile to what you need. http://www.amanatool.com/products/router-bits/profiling-router-bits/ball-end-router-bits.ht...
