1)OD Undersized -0.015mm beyond drawing limit.|2)OD undersized during the re-pass operation as the re-pass ran twice.|3)Re-pass ran twice with same -0.15 wear offset as the operator provided +0.2mm wear offset during the insert change.|4)To maintain stock in the ID after the insert change the operator provided -0.2mm in the initial stage and after measuring the diameter he provided -0.15mm to remove the stock and finish to the drawing requirement during this time the re-pass operation was carried out and resulted in diameter was undersized.|5)Operator was unaware that the program for OD runs twice with different stock levels to achieve finish in the final operation
