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.
A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center.
Functional gear testing, also known as total radial composite deviation, is a method of looking at the total effect of gear errors. This test method simulates the conditions under which a set of gears is likely to operate as a result of the gears meshing together.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
