Boring / flycutting on CNC mill

[kvom]

Are flycutters commonly used with CNC mills?

For boring, I know you can machine a round pocket, but I doubt that the finish would be as good. Does it make sense to use a boring head on a CNC mill, at least for the final pass?

Sure, kvom, you could do all of the above, just depends.

In the case of a boring head versus interpolating the hole, I doubt if surface finish would be the deciding factor. Rather, it would be accuracy of the bore. The boring head will do a better job, but it will be a lot slower, and probably less automated unless you have a real expensive one. If you have to hold real tight tolerances for a bearing, you probably need a boring head. If 0.001" is good enough, interpolate.

RE the flycutter, you could use one, but a nice face mill will get the job done faster.
