Mitutoyo MiScan Vision System Measures Array of Workpiece Sizes

Mitutoyo’s MiScan vision system is a multiple-sensor, microscopic-form measurement system that uses a combined coordinate measuring machine (CMM) and vision measurement system technology to provide highly accurate autonomous scanning of microforms to larger workpieces. The system features a microform scanning probe, the MPP-Nano, which can use styli as small as 125 μm in diameter for measuring microscopic workpieces, while an observation camera is said to facilitate easy measurement setups. An SP25M scanning probe is also supported to enable measurements of small- and large-sized workpieces.

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. According to the company, this system enables high-accuracy, highly efficient measurement of miniature optical tubes used in micro camera arrays. The MPP-NANO can also measure the contour of high-degree aspheric lenses used in vehicle-mounted cameras with high accuracy.

The company says that using the MiScan Vision System with the MPP-Nano also enables users to efficiently scan microscopic gear teeth. This functionality is made possible by entering each nominal using Gearpak, Mitutoyo’s gear teeth evaluation software, to evaluate the tooth profile error and tooth trace error. The system can also scan measurement of microscopic feature detail, such as precision punches and dies, using extra-small-diameter styli, which are available with diameters as small as 125 μm. It is also said to enable scanning measurement using the stylus on holes with a maximum aspect ratio of 17:1.
