I have found that some cheaper miter saws (even expensive ones) are not always calibrated to exactly 45 degrees.
I highly recommend doing some test cuts with your saw using some cheap pine 1×4’s. Verify the cuts with a hand square, then adjust your saw if needed.
Also, a sharp, fine tooth blade is absolutely nesessary when working with Oak. A dull blade will burn & warp as it cuts making clean 45’s nearly impossible to achieve.
