what you want to do is not clear.
if you want to chamfer the inner edge of the bore at dia 346mm (456 - 110) just use a 90 degrees chamfer tool and cut a circle with G02/G03 at dia 346. using G41/G42 diameter compensation. adjust the Z minus until the tool just touches the edge of the tube and you get a chamfer.
G00 X0 Y150.0
G43 Z100.0 H1
G1 Z-10.0 F500 (adjust Z- to achieve required chamfer size)
G1 G42 Y173.0 D1
G2 X0 Y173.0 J-173.0
G28 U0 V0 W0
