Yes Neal I agree with your reply but as the tolerance required was to H7 which on a 155 dia hole is -0.000mm ton +0.040mm then circular interpolation is more than adequate.
Also in a general machine shop who can measure roundness to 0.005mm. In this instance I consider that a boring process is over engineering.
