Mitutoyo ’s MiStar 555 Eliminates Need for Environmentally Controlled CMM Enclosure
Mitutoyo’s MiStar 555 CNC shopfloor coordinate measuring machine (CMM) operates without compressed air and on conventional 120-V, 20-A electrical service with movement speeds of 606 mm/sec. and acceleration of 2,695 mm/sec.² (3D).

The modular control unit and PC are stored in the base of the main body structure, reducing the installation area compared to a conventional moving-bridge model. The MiStar is also equipped with a robust detection system with a high resistance to airborne contaminants, eliminating the need for environmentally controlled enclosures.
The MiStar features the Mitutoyo Smart Measuring System, which enables monitoring of the operation state required by so-called smart factories and a Status Monitor that retrieves current CMM status features using the MTConnect protocol. Condition Monitor collects and evaluates different operational information such as measuring, movement lengths, machine error and probe functions for long-term preventive maintenance and machine use statistics.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
Different instruments (and different operators) are prone to different errors.
Guidelines used to standardize the measuring process can provide a good basis for making gage decisions.
