Mitutoyo's MiScan Measures Microscopic Part Features

Mitutoyo America’s MiScan, a multi-sensor microscopic-form measurement system, combines coordinate measuring machine (CMM) and optical measurement technology. The MPP-Nano probe can use styli with diameters as small as 125 micrometer to measure details of parts ranging from optical components to precision punches and dies. The observation camera eases measurement setup, the company says. The SP25M scanning probe is also supported, enabling measurement of small and large workpieces and features.
The system utilizes the same image head as Mitutoyo’s Quick Vision measuring system. The Quick Vision Apex lighting system is also incorporated, providing multiple lighting functions and evaluation software.
The MiScan enables efficient, high-accuracy measurement of miniature optical tubes for micro camera arrays. The MPP-Nano can also measure the contour of high-degree aspheric lenses used in vehicle-mounted cameras.
Previously, efficient scanning of microscopic gear teeth has been difficult, the company says. The MiScan, together with the MPP-Nano, addresses this application. The user enters each nominal using GearPak, Mitutoyo’s gear teeth evaluation software, to evaluate the tooth profile error and tooth trace error.
Different instruments (and different operators) are prone to different errors.
Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.
Few manufacturing companies rely on ballbar testing to maintain machine tool accuracy as thoroughly as Silfex. Now, advanced training and a move to a Renishaw QC20-W wireless system have enabled the company to take the benefits of ballbar testing to a higher level.
