New retrofit high-speed laser scanning systems
Keywords: Lasers, Scanning, Measurement
Laser scanning devices have become a well- established technology, which is currently available for use on CMM's. Mitutoyo introduces the Metris LC range of high-speed laser scanning probes for use on their CMC measuring machines (Plate 2). Available as a retrofit system, enabling the CMM to be transformed into a state-of-the-art, high-speed, non-contact digitizing system.

Using the LC probe with a conventional CMM, reportedly removes or reduces many of the restrictions of contact measurements. At present, laser scanning enables complete modelling and inspection of even complex free-form,multi-filleted or featured parts. Due to its non-contact nature, laser scanning is also suited for measuring flexible or fragile materials, which often present severe challenges for touch probes due to the risk of indentations or surface scratches. Full part digitisation is provided and additional software modules are available, for CAD to part inspection and reverse engineering. This software and hardware combination is said to allow measurement and inspection cycle times to be drastically reduced, hence increasing measurement efficiency and reducing costs.
The LC probes are designed to operate when attached to the Renishaw PH10M probe head, which results in no extra wiring. The probe is also compatible with the ACR-1 and ACR-3 auto-change racks, for making easy interchange between the optical and contact probes, which reduces the cycle time when both contact and non-contact measurements are required.
A range of probes is available. The LC15, which has a 15 × 15 mm field of view, is used for high precision work such as turbines and small connectors. The LC50 is the workhorse probe with a 50 × 50 mm field of view, and it is capable of scanning both small and large objects, quickly and effectively. A more recent addition to the range is the XC, or cross scanner, which has been developed specifically for feature measurement in sheet metal applications.
Laser scanning from Mitutoyo is believed to open a new world for manufacturing, since important time is saved during the design, prototyping,pre-production and production cycles. Also the design engineers are provided with up to date and accurate information about the quality of the parts, which ultimately saves time and cost within the manufacturing cycle.
