Turning a diameter turn just enough to clean up a diameter so as to have a completely round diameter with no low-spots (because of irregularity in the stock material). Once a section has been successfully turned as such. Bring the tool away on the Y axis only (without changing the cross-slide setting) and measure the diameter with a Micrometre or Vernier Calliper. When you have established the diameter press the X button (shown right), enter the value and press the ‘ENT’ key to store the value. The DRO will automatically convert radial movement to always read new the diameter on successive cuts. It is advisable to leave a small amount extra on the diameter and re-measure before going for your finishing cut and final diameter for the sake of accuracy. |
