I have a part with a 28mm flat bottomed hole that is 8mm deep. I pre-drill the hole with a 25mm slot drill, to get an 8mm deep 25mm flat-bottomed hole and now want to bore it out to its final diameter. I want to use a 10mm end mill, position the tool at the bottom of the hole and then bore out to the final diameter at this full depth.
I want the tool to approach the final diameter using a spiral path and not by stepping over but I can't find out how to do this. I have tried 2D bore, 2D circular and 2D contour but can't find a way to do this in any of them. It's the kind of thing I could do quite easily, if I was typing G code in directly, using the G3 command.
Can anybody help, please?
Thank you.
