15 -Machine Tool Metrology: Specifying and Verifying Parametric Errors

Dr. Jimmie A. Miller, University of North Carolina at Charlotte

Tuesday, November 14, 2023
2:00 PM – 6:00 PM (EST USA)

This tutorial is of interest to anyone who uses or builds instruments which have positioning stages. Procurement and subsequent testing of machine tools requires the buyer and seller to speak the same language. This tutorial reviews international standardized parametrization and tests which are used to specify machines for procurement or usage including determining when a rebuild or correction may be warranted. Topics include determinism, carriage errors, instrumentation for measuring carriage errors, analysis of acquired data to determine the desired measurand parameters. Other tests such as carriage alignment errors, some dynamic errors will also be addressed. Time permitting modeling of machines for error correction may be introduced.

Dr. Jimmie Miller received his doctoral degree in (nano/precision) engineering from the University of Warwick UK under the primary direction of Dr. Robert Hocken (UNC Charlotte) along with Dr. Stuart Smith (UW) and Dr. Keith Bowen (UW). He has worked full-time since 1993 as a Research Engineer at the University of North Carolina at Charlotte, including roles as the Chief Engineer and Deputy Director of the Center for Precision Metrology. He holds four patents in manufacturing/metrology. He also teaches a graduate class in machine tool metrology, which includes a hands-on practicum that can be taken remotely in conjunction with a four-course graduate certificate series. He also holds degrees in Electronics Engineering (AAS), Math (BS), Physics (BS) and Microelectronics (MES). Jimmie has been involved with ASPE since 1990, serving on the ASPE Board from 2016-2018. He is a regular reviewer for the Precision Engineering Journal. He also authored the chapter entitled Metrology in the book Basics of Precision Engineering (2018).
