CMM Offers Repeatability at High Speeds
IMTS 2018: The Optiv Performance 322 CMM from Hexagon Manufacturing Intelligence can be upgraded to meet the needs of various applications.
The Optiv Performance 322 benchtop multi-sensor coordinate measuring machine (CMM) from Hexagon Manufacturing Intelligence can be upgraded to meet the needs of various applications. Weighing 180 kg, the fixed-bridge and moving tabletop machine is light enough to be placed directly on existing workbenches and relocated without recalibration. The machine offers accuracy and repeatability at high speeds (as fast as 300 mm/sec.) because of the stiffness of its granite construction. The CMM is suitable for the inspection of sheet metal stampings and injection-molded plastic parts, profile scanning and more.
Equipped with PC-DMIS software, the CMM is designed for flexibility and can measure a range of different parts with minimal turnaround times. It is available in an entry-level vision-only configuration. Its 3D accuracy specification and future-ready pre-cabling facilitate upgrades. It accepts a range of contact and non-contact sensors, reducing user requirements for multiple products in the inspection area. The system is built on a modular concept, so the sensors, controllers, PC and measuring software can be customized to user requirements.
The CMM features temperature compensation technology that calculates a correction value for measurement deviations, which provides stable results.
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.
Here are some of the tools and techniques for making sure machine tools stay at peak performance levels.
