corner cabinet mitered backs

[Jim Carter]

How are you guys joining the back of your corner cabinets.
I would like to use my router to cut a 22.5 degree bevel edge for joining with adjacent back to create one of the two 45 deg joints in the backs of a corner cabinet with clipped corner.
could it be as easy as drawing the profile cut in e cabinets and picking the right tool in mdf door settings to cut this part in a nest.

Hi Jim
It could be done that way but would probably be simpler to do those parts as DXFs and specify the correct cutter there.

Cutting a 45 angle in a nest
I found this discussion last night, and it answers allot of my questions.
But I wonder about the DXF file you are creating, and nesting.
Do you create a different file for each size you will be cutting, then check off the backs which need mitering in the e cab file?
To cut this miter one at a time after they have been cut to size in a nest,has any one developed one jig to profile one edge on any size piece?
Where have you found 22.5 deg bits? I did not see any in the online store.

Jim you would create a seperate DXF for each part. I would make the backings in my eCabs drawing out of a "no machine" material so I could get the correct sizes for the DXFs. As far as my own experience is concerned I do not cut the miters on the CNC but cut the back panels oversized in the nest and cut the bevels on a panel saw. For the number of backings one would have to do for a relatively infrequent situation it is the easiest way I guess without the investment in special tooling.

thanks Nick
you make allot of sense.
