planes at high speed. Using its white light interferometer, the QuickVision performs highly accurate 3D measurements in microscopic areas for surface analysis, small-diameter hole depth as well as space measurements on circuit boards. Combining these features with the CCD camera that magnifies images, Portsmouth University can easily measure features and values previously beyond the remit of the equipment that was replaced. “Our PhD researchers are undertaking some really interesting work where the Formtracer SV-C3200 is integral to research. One project involves drilling composite materials with a multitude of tools on Hurco machines to study the thermal stability, hole concentricity and precision levels when utilising a variety of tools at different feed and speed parameters. This study will improve our understanding of the impact that machining parameters and tools have on the precision and surface finishes of holes in a multitude of composites.” Another university PhD researcher is utilising the precision, ease of use and the documentation recording features of the Formtracer SV-C3200 to study the deformation of glass and glass reinforced plastics (GRP). “This student is making Micro and Nano indentations in glass and GRP to understand the deformation process in these materials. The 80mm/sec fast traverse of the Formtracer certainly improves measurement efficiency over its predecessor. The new FORMTRACEPAK contour analysis software offers contour tolerancing, pitch calculation functions and a data combination function that facilitates the analysis of features such as small holes and indentations.” “This software can conduct surface roughness analysis that conforms to standards such as ISO, JIS and ANSI. This validates data collected and gives it greater relevance to industry, enhancing employment prospects of researchers. Furthermore, the FORMTRACEPAK has graphic analysis functions that work in conjunction with the Mitutoyo MiCAT (Mitutoyo Intelligent Computer Aided Technology) system to generate graphics and statistics from measurements on a single page report. This information reporting is a revelation for our researchers, especially when compared to our old equipment,” continues Mr Keeble. This ease of use is also mirrored in the new Roundtest RA-1600 that incorporates the Mitutoyo ROUNDPAK measurement and analysis software. At Portsmouth University, the Roundtest RA-1600 is certainly considered as an ‘all-rounder’ in metrology terms. Alluding to the application of the Roundtest RA-1600, Mechanical Lead Technician, Mr Dan Wiggins says: “My department use the Roundtest RA-1600 daily. Whether its calibrating and confirming dimensions of machined and 3D printed projects or PhD researchers measuring drilled holes; the radial and axial precision level of 0.02 microns certainly meets all our dimensional needs.” The ROUNDPAK software supports roundness, flatness and parallelism and it includes an offline teaching function that enables virtual execution of measurement operations in a 3D simulation window. By storing and indexing this data, libraries of sequences can be compiled and custom reports with 3D graphics can be generated. With brittle projects such as glass that are measured in the realm of nanometres, the university can rely on the QuickVision Apex. The QuickVision has a non-contact displacement sensor that uses the epaxial chromatic aberration of the white light source to measure very small steps and curved It is this recording of data that has made the four new Mitutoyo installations such a revelation to the university. As Mr Keeble concludes: “We couldn’t ask for anything more from the new equipment. The ease of use is vastly improved, as is the reporting, tracking and storing of data. The new kit is faster, more efficient and intuitive than ever before and this user friendliness is a key factor for an education establishment like ours.” 57
