According to BIG Kaiser, digital tool sensing removes the potential for error inherent in manual measurement systems. The system does not rely on the operator's sight and judgment to focus and align tools within its optics in order to assure reproducibility of precision settings no matter which operator uses the instrument.
After inserting the tooling in the spindle, the operator sets maximum diameter by reading simple digital values and following color codes on a personal computer monitor. The computer replaces the digital readout used on other types of presenters, so the operator does not have to learn to operate two sets of controls — digital readout and computer monitor. The EzVision control features a centering indicator box for presetting angular cuts, and may also be used to calculate nose radii and angles.
