UHR Laser Profilometry Equipment for 155mm M776 M284 cannon bore measurement

The Army is seeking a supplier to provide UHR Laser Profilometry Equipment for 155mm M776 and M284 cannon bore measurement. The equipment must be compatible with the existing Video Bore Inspection System and Laser Bore Inspection System measurement equipment. The deliverables include a 155mm Large Caliber Laser Profilometry Scanner Assembly and a 155mm Large Caliber Calibration Ring. The key specifications for the scanner assembly include axial scan resolution, rotary scan resolution, sensor resolution, measurement repeatability, and measurement accuracy. The key specifications for the calibration ring include configuration, step calibration uncertainty, and certification. Some key points to consider are: • The equipment must be fully compatible with existing VBIS, LVDT, and LBIS equipment. • The scanner assembly must support 155mm bore sizes. • The calibration ring must have a 3-step ring configuration with each step diameter within the laser measurement range. • The step calibration uncertainty must be better than 0.00005 inch or 1.27 μm uncertainty. • The certification must be NIST Traceable.
