Interference-Free Inspection Path Generation for Impeller Blades Using an On-Machine Probe

Inspecting an impeller is a challenging task in manufacturing automation due to its free-form surface and overlapping and twisted blades. Existing inspection method by a Coordinate Measuring Machine is complex and time consuming, because of offline reclamping and manual operation. Automatic on-machine inspection without transferring and reclamping workpiece is a promising technique, and has found ...
