Both an accurate machine design and an adequate metrology loop definition are critical factors when precision positioning represents a key issue for the final system performance. This article discusses the error budget methodology as an advantageous technique to improve the measurement accuracy of a 2D-long range stage during its design phase. The nanopositioning platform NanoPla is here presen...

Transmission error is a measure of the positioning accuracy of a gear system. This has been widely documented in gearing for many years as the source of problems in noise and vibration. It is a result of errors in the contact conditions which affect the driven gear with respect to the rotation of the driver gear. This research aims to present a better understanding of the basic kinematics of wo...

T he cell therapy industry (CTI) is no longer a cottage industry; it is a distinct and sustainable component of the global healthcare sector (1). Today, CTI prospects are strong, with annual revenues exceeding US$1 billion/year, supported by improving investor sentiment and public support (1–3). The next phase of CTI growth — toward a multibillion-dollar global industry — will depend on the bio...

The orientation of SFF-manufactured parts can have a signiicant eeect on the quality of the parts, in both surface eeects and strength. Currently, orientation is either ignored or set on the basis of experience. This paper takes some simple experiments and creates quantitative measures relating diierent aspects of part quality to orientation. This leads to several computational tools for optimi...
