Part handling can be an issue when using a coordinate measuring machine (CMM) to inspect small parts. New Scale Robotics not only solves the part handling issue but adds the significant additional new benefit of providing in-line measurement to improve CMM throughput.
In this case study with OptiPro Systems, New Scale’s precision gripper/caliper tool is installed on a UR3e cobot, and paired with a Zeiss O-Inspect CMM system.
Several different types of parts within a family of optics are to be inspected. The robot gripper/caliper:
- picks a part
- accurately loads it into the CMM
- takes a preliminary measurement
- relays the measurement data to Zeiss Calypso software
The Zeiss CMM uses the measurement information to identify the part type and determine which measurement procedure to perform.
After measuring the part, the CMM relays information back to the robot indicating whether the part is good or bad. The robot sorts the parts accordingly when placing them in the output trays.
