Abstract: A method includes scanning a thickness of a workpiece in at least one point using a thickness sensor, determining that the workpiece is out of alignment in a cutting machine using the thickness sensor, and realigning the workpiece relative to the cutting machine or adjusting a machining operation using a controller of the cutting machine in response to determining that the workpiece is out of alignment.

Abstract: A downhole tool assembly includes a tubular having a turned-down region and a raised region extending axially away from the turned-down region. An inner diameter surface of the tubular in the turned-down region has a higher ellipticity than an outer diameter surface in the turned-down region. The outer diameter surface in the turned-down region defines a first center that is offset from a second center defined by the outer diameter surface of the tubular away from the turned-down region. The downhole tool assembly also includes a cylindrical tool disposed at least partially in the turned-down region.

Abstract: A method and downhole tool assembly, of which the method includes measuring a thickness and a location of an outer diameter surface of the tubular at a plurality of transverse planes of the tubular, simulating a cutting process to determine a position for the outer diameter surface of the tubular in a lathe, such that, after the cutting process that was simulated is conducted, the thickness of the tubular is greater than a minimum thickness and an outer diameter defined by the outer diameter surface of the tubular is less than or equal to a maximum diameter, positioning the tubular in the lathe based on the simulation of the cutting process, cutting the outer diameter surface of the tubular to reduce the outer diameter thereof to at most the maximum diameter and thereby form a turned-down region, and positioning the downhole tool on the tubular in the turned-down region.
