The development of an error compensation model for coordinate measuring machines (CMMs) and its integration into feature measurement is presented. CMMs are widespread and dependable instruments in industry and laboratories for dimensional measurement. From the tip probe sensor to the machine display, there is a complex transformation of probed point coordinates through the geometrical feature m...

This paper describes the development of an analytical model to describe a novel three-axis vibrating micro-scale probe for micro-coordinate measuring machines (micro-CMMs). The micro-CMM probe is vibrated in three axes, in order to address the problems inherent with microand nano-scale co-ordinate measurements caused by surface interaction forces. These surface forces have been investigated and...

Longline fishery targeting tunas and tuna-like species is known to produce a significant amount of catch not only for the target species, but also ecologically related like sharks, marine turtles, sea birds mammals. Recognizing this seriousness, tuna regional fisheries management organizations (t-RFMOs) have established conservation measures (CMMs) reduce bycatch and/or interaction with ecosyst...

We describe the design of a tenant interface for energy and maintenance systems (TIEMS) in commercial buildings. TIEMS is designed for use by occupants (tenants) of commercial buildings. Our hypothesis is that by allowing tenants access to information from the energy and maintenance systems and by giving them some control over these systems, energy and maintenance performance can be improved. W...

Point Laser Triangulation (PLT) probes have significant advantages over traditional touch probes. These advantages include throughput and no contact force, which motivate use of PLT probes on Coordinate Measuring Machines (CMMs). This document addresses the problem of extrinsic calibration. We present a precise technique for calibrating a PLT probe to a CMM. This new method uses known informati...

VDI article 2617 1 specifies characteristics to describe the accuracy of articulated arm coordinate measuring machines (AACMMs) and outlines procedures for checking them. However the VDI prescription was written with a former generation of machines in mind: manual arms exploiting traditional touch probe technologies. Recent advances in metrology have given rise to noncontact laser scanning tool...

The evaluation of measurement uncertainty is complex as there are a variety of sources of errors and variation. The task of combining all the sources of errors, according to the guidelines in GUM [1], to come up with an uncertainty budget is not an easy one. There is no single uncertainty statement that can be generally applied to all CMMs. The uncertainty for every individual CMM is specific t...

The rapid proliferation of coordinate measuring machines (CMMs) triggered the need for precise and rigorous formulations of each tolerance concept. In this paper, we employ the concept of con guration space of symmetric features to de ne each type of datum features and orientation tolerances. The establishment of datum features and orientation tolerances are formulated in an linear programming ...

We investigated the influence of periodicity, misalignment, and disorder on the magnetic resonance gap of split-ring resonators (SRRs) which are essential components of left handed-metamaterials (LHMs). The resonance of a single SRR which is induced by the split is experimentally demonstrated by comparing transmission spectra of SRR and closed ring resonator. Misaligning the SRR boards do not a...
