Inspection

Patriot employs a team of inspectors that verify quality in-process and prior to shipment.

A tailor-made nine-meter Hexagon Delta Slant Coordinate Measuring Machine (CMM), an Ultra High Accuracy Hexagon Global S Chrome CMM, and/or a Leica laser tracker is used with Valisys™ and PC-DMIS to validate part accuracy post-machining.

CMM inspection is performed in a climate controlled environment where we measure complex geometric parts. To compress lead-time, we use Valisys™ and PC-DMIS to develop programs in advance. We also have a Leica laser tracker for inspection of any part exceeding the size of our CMM. Additionally, on-machine probing can be leveraged for determination of large, complex features immediately after machining.

Patriot has extensive experience with ASME Y14.5M Geometric Dimensioning and Tolerancing (GD&T) requirements and is accustomed to using a catalog of nearly 1800 calibrated, precision instruments for conventional surface and dimensional measurements. Our Mahr Surface Profilometer also allows for data capture of unique and complex surface characteristics.

Machinists perform in-process measurements to assure machining process capabilities are maintained and completed per AS9102 requirements. We use Infinity QS Statistical Process Control (SPC) software to compare the specifications to the output and verify the process meets our customers’ statistical specifications.

Customer Specified Key Characteristics (KCs) are maintained per AS9103. First Article Inspections (FAIs) are completed and recorded per AS9102.
