Precision Drilling

PAR Systems designs optimal drilling solutions for the aerospace industry that are equipped with automatable features for improved efficiency and performance.

Advanced Manufacturing Techniques Increase Production Efficiency
PAR utilizes many advanced manufacturing techniques and technologies to ensure the most efficient and effective precision drilling possible.

Full Scanning

Techniques such as full assembly scans work by understanding the as-presented configuration of a work piece and uses this data to compare to the nominal model. The system then calculates these errors and transforms these points to create new tool paths for drilling operations. This results in higher-quality holes that have been adapted to best fit each piece.

Our drilling machines run on Polyworks Inspector™, a universal software system that provides three-dimensional analysis and quality control on parts, tools, assembly processes, and more. This intuitive software offers a centralized data hub, making it easier to integrate into existing processes and to manage key quality and performance metrics.

Measurement Workflow

PAR also utilizes Polyworks Inspector™ to preconfigure the measurement workflow for all your measurement devices, employing piece measurement templates. The system allows users to predefine multiple measurement templates within one inspection project and automatically adapt measurement objects and sequences to different measurement principles using conversion tools.
