## Description

New 120-155mm Cannon Laser Bore Chamber Add-on Kit capability for 120-155mm cannon gun tubes. This acquisition shall be capable of use for: Precision non-contact bore measurement of 120-155 mm cannon smooth and rifle gun tubes.

Measurement to the end of the muzzle with a guide tube adaptor that attaches to the muzzle, for supporting none-contact gauge and rigid or self-propelled delivery unit Laser cannon tube bore and chamber gauging kit shall employ a set of opposed high-resolution sensors that are automatically none-contact the bore chamber along its length to muzzle end of cannon tube.1.

The 120mm Cannon Laser Add-on Bore Gauging Kit shall be operated as a complete turn-key unit and include the following major components:120mm Cannon Bore Chamber Add-on kit Guide tube assembly Certified calibration ring (5 steps) Laser Bore Chamber Calibration Workspace Software2.

The 155mm Cannon Laser Add-on Bore Gauging Kit shall be operated as a complete turn-key unit and include the following major components:155mm Cannon Bore Chamber Add-on kit Guide tube assembly Certified calibration ring (5 steps) Laser Bore Chamber Calibration Workspace Software3.

The Laser bore chamber scanning modules shall meet the following specifications Axial scan resolution: 0.25mm (0.01 inch) minimum Rotary scan resolution: 0.1mm (0.004 inch) minimum Sensor Resolution: 0.005mm (0.00025 inch)Laser spot size: 0.050mm (0.002 inch) minimum Measurement repeatability: 0.012mm (0.0005 inch)Measurement Accuracy: minimum of 0.025mm (0.001 inch) in bore and 0.05mm (0.002?) in bore chamber Angular Sampling Resolution: Variable ? up to 0.1 degrees per sample (3,600 samples per revolution)Measuring Range (diameter): Chamber Bore Size Minimum Range Maximum Range120mm 4.7000 in 6.3000 in155mm 6.1950 in 6.8000in 4.Each Calibration Ring shall have five steps (diameters) minimum within the center 75% of the range of the gauge The Calibration Rings shall be measured with a NIST-traceable.

A2LA Accredited, ISO 17025 and ANS/INCL Z540-1-1994 standards5.Automatic Sensor Calibration software shall be capable of conducting an automatic calibration routine Calibration Software shall provide a Pass/Fail display of calibration test results If the calibration fails, the software shall automatically calculate corrected calibration parameters Calibration software shall allow the operator to manually adjust offset and slope of the calibration algorithm6.

Data analysis shall be supported by existing analysis software, with modification if required to meet the requirements in this specification Analysis modules for post processing of data including but not limited to calculating: land and groove diameter, area, statistics, reference subtraction, rotate data, remove centering offset, remove undefined data, remove bad data, variable median filter, averaging filter
