Im trying to finish a surface after roughing and want a nice concentric tool path offset each time (basically a facing pass but following an arc profile (see pic). Despite trying almost everything (inc. spiral with concentric circles checked) I cannot get it to behave properly. Can anyone point me in the right direction please? Thanks a a lot!
Are you using a bull endmill with the appropriate finished radius? I'd use 2D Contour, enabling Roughing Passes and turning on Stock Contours (selecting the area you wish to machine). This will give you concentric toolpaths as you are looking for.
Hi @Anonymous
If you are using a ballnose endmill to cut this, you could use the morph strategy. This requires curve selections for the toolpath to follow so it will ensure your toolpath is concentric and is a bit easier to generate than some of the other toolpaths like circular etc. I've attached some images that shows this.
Hope this helps

Thanks so much both @seth.madore & @mathew.hutton , 2D contour worked perfectly for this specific part but the morph is a good alternative for another time. I've attached photos for the benefit of anyone else looking in future.
