The VTS SF-45 acquires a variety of tool dimensions in a single instant using the principle of shadow projection where an illuminated objects projects its shadow onto the camera. These measurements include tool length, static and dynamic tool diameter, the tool run-out and cutting-edge radius. With a resolution of 0.1 µm, the VTS enables measurement of tools with diameters as small as 10 µm with repeatability of 0.2 µm, providing a higher level of accuracy than touch probes or lasers in small applications.
