Editorial
‘Back to business’ is the new normal … again December is a shadowy month. It occupies that brief span on the calendar when the lingering reminiscences of the current year compete with the looming ambitions of the next. A year ago, such reminiscences would have been dominated by the shadow of COVID-19’s sickness, shutdowns, and supply chain disruptions. This shadow remains today, but it has diminished in light of a steady stream of new...

Understanding Resolution, Accuracy, and Repeatability in Micromotion Systems Resolution, accuracy, and repeatability are all metrics for measuring the critical requirements of motion systems. In addition to defining performance, they fundamentally define and affect system complexity, cost, and development time. Understanding these terms and how they are measured can help designers and integrators to further refine and optimize their instrument requirements. Consider a...

Deep-Sea Charter Vessel Helps TRUMPF Sidestep Supply Chain Woes With the effects of a multiyear pandemic and a war in Ukraine continuing to permeate global commerce, logistics operations face a treacherous set of circumstances. For sea freight transportation, increased loading times at port — which then leads to longer wait times for loaded vessels before departure — means goods often arrive after significant delays. Paired with rising shipping costs, the...
