Timothy A. Sprock, Michael E. Sharp, William Z. Bernstein, Michael P. Brundage, Moneer M. Helu, Thomas D. Hedberg Jr.
In traditional manufacturing operations management systems, the four pillars of ISA-95 (production, quality, maintenance, inventory) are each implemented as separate software systems. Each system independently manages its own data, operational decision

On-Machine Measurement Use Cases and Information for Machining Operations

August 2, 2019
Author(s)
John A. Horst, Thomas D. Hedberg, Allison Barnard Feeney
Digital thread standards for both dimensional metrology and industrial machine tool operations have been defined in standards organizations and successfully implemented in several commercial manufacturing production operations. A next step is to define a
