The additional controls in AS9100 create tighter oversight of supply chain partners and emphasize configuration management throughout the product lifecycle. This progression helps machining facilities transition from commercial work to certified aerospace programs.
The Role of AS9100 in CNC Machining
Implementing AS9100 in CNC Processes
AS9100 shapes every aspect of CNC machining by requiring detailed process planning and operator qualification records. Shops must validate machine programs through simulation and first-piece verification before full production runs. Certified as9100 machining cells maintain calibrated tooling, controlled fixtures, and in-process inspection points that catch deviations early. Implementation includes creating work instructions that specify speeds, feeds, and coolant types for each material. Teams document setup sheets and tool lists so any operator can reproduce results consistently. The standard also requires regular preventive maintenance on CNC equipment to prevent unplanned downtime that could affect delivery schedules.
Quality Control and Tolerances in CNC Machining
Tight tolerances define aerospace components, and AS9100 certification enforces measurement systems capable of verifying those dimensions. CNC machining under this standard incorporates statistical process control and capability studies that prove processes remain stable. Inspectors use coordinate measuring machines and surface finish profilometers calibrated to traceable standards. Any out-of-tolerance condition triggers a formal nonconformance report and root cause analysis. The certification demands that operators understand how material properties and cutting forces influence final dimensions. This disciplined approach keeps scrap rates low and ensures every AS9100 CNC machined part meets drawing requirements before shipment.
Case Study: AIP Precision Machining's AS9100 Journey

The company updated its quality manual, trained staff on new procedures, and installed additional inspection equipment. Within months, AIP achieved certification and began winning contracts for flight-critical brackets and housings. The journey revealed gaps in supply chain documentation that the team quickly closed by qualifying new vendors. AIP now runs multiple five-axis CNC cells under AS9100 controls, delivering parts with complex geometries to customers who previously sourced overseas. The certification has become a core marketing asset that signals reliability to the broader aerospace industry.
Transitioning from Prototype to Production
The Prototype Phase: Key Considerations
Prototype machining under AS9100 certification focuses on proving manufacturability while capturing lessons for later production. Engineers evaluate material behavior, tool life, and fixturing during initial runs to refine processes. Teams document every adjustment so the same parameters transfer smoothly to higher volumes. AS9100 requires formal design reviews that include manufacturing input before locking the final configuration. Prototype parts receive the same traceability and inspection rigor as production units, building confidence in the eventual process. This disciplined approach prevents costly redesigns once full-scale orders arrive.
Managing Risk in Aerospace Manufacturing
AS9100 certification places strong emphasis on risk management throughout the manufacturing cycle. Teams identify potential failure modes in machining operations and implement controls such as redundant inspections or backup tooling. Risk registers track issues related to material availability, machine capability, and operator skill levels. Regular reviews update mitigation plans as new information emerges. The standard requires evidence that risks to product safety receive the highest priority. Companies that embed risk thinking into daily decisions reduce surprises during customer audits and production ramp-ups.
Supply Chain Management Under AS9100
AS9100 certification extends quality requirements to every supplier in the chain. Machining companies must evaluate and approve vendors based on their ability to deliver conforming material and parts. Approved supplier lists receive regular performance reviews that cover on-time delivery, quality metrics, and responsiveness. The standard also mandates flow-down of customer requirements to sub-tier suppliers. Aerospace manufacturers maintain ITAR compliance records when handling controlled technical data. Strong supply chain management under AS9100 protects schedule integrity and prevents counterfeit materials from entering the production stream.
Materials and Techniques in AS9100 Certified Machining
Machining Metals: Aluminum, Copper, and Plastics
AS9100 certified machining services routinely process aluminum alloys for lightweight structural parts and copper components for electrical applications. Shops select cutting tools and speeds based on each metal’s thermal properties to maintain tight tolerances. Plastics such as PEEK and Ultem require different fixturing strategies because of their lower rigidity. Certified facilities document material certifications and lot traceability for all metals and plastics. Proper chip evacuation and coolant selection prevent work hardening in aluminum and burr formation in copper. These controlled practices ensure consistent surface finishes across production batches.
CNC Milling Techniques for Aerospace Components
CNC milling under AS9100 certification combines high-speed roughing with precision finishing passes to achieve complex aerospace geometries. Five-axis milling centers allow single-setup machining of contoured surfaces on turbine housings and actuator bodies.
