Frequently Asked Questions<\/b><\/h2>\n
What is ITAR and why is it mandatory for defense CNC machining?<\/b><\/p>\n
ITAR (International Traffic in Arms Regulations) is a set of US government regulations administered by the US Department of State’s Directorate of Defense Trade Controls (DDTC) that controls the export, import, and temporary import of defense articles, services, and related technical data listed on the US Munitions List (USML). Any company that manufactures, exports, imports, or provides technical services related to ITAR-controlled hardware must be registered with DDTC and comply with ITAR export licensing requirements. For a CNC machining supplier to machine ITAR-controlled defense hardware, they must be registered with DDTC and must restrict access to the technical data and the machined parts to US persons only.<\/span><\/p>\nWhat is CMMC and which defense CNC suppliers need it?<\/b><\/p>\n
CMMC (Cybersecurity Maturity Model Certification) is a US Department of Defense (DoD) cybersecurity framework that requires prime contractors and their supply chain to demonstrate specific cybersecurity practices for handling Controlled Unclassified Information (CUI). CMMC Level 1 requires 17 basic cybersecurity practices. CMMC Level 2 requires 110 practices aligned with NIST SP 800-171. For CNC machining suppliers handling defense design data, CNC programs, and technical drawings that constitute CUI, CMMC Level 2 certification is increasingly required by DoD prime contractors. As of 2025, CMMC is being phased into new DoD contract requirements.<\/span><\/p>\nWhat materials are most common in defense CNC machining?<\/b><\/p>\n
4340 alloy steel (hardened 38\u201348 HRC) for gun components, armour-piercing projectile bodies, and high-strength structural defense hardware. 17-4PH and 15-5PH precipitation-hardened stainless for corrosion-resistant structural defense components. Titanium 6Al-4V for airborne defense structure (fighter aircraft, UAVs, missiles). 7075-T6 and 7050-T7451 aluminium for airframe and avionics housing structural defense components. Inconel 718 for high-temperature defense propulsion and combustion components. Tungsten alloy (95% W) for kinetic energy penetrators and radiation shielding.<\/span><\/p>\nWhat tolerances do defense CNC components typically require?<\/b><\/p>\n
Defense structural CNC components: typically \u00b10.025\u20130.050 mm on non-critical dimensions; \u00b10.005\u20130.013 mm on precision fits and sealing surfaces. Defense optical and electro-optical housings: \u00b10.005\u20130.010 mm on bore and window aperture fits. Proximity fuze and munition components: \u00b10.025\u20130.050 mm typical; tighter on arming and safety mechanism interfaces. Gun barrels: rifling tolerances to \u00b10.002\u20130.005 mm on groove geometry for accuracy. Missle and projectile components: diameter tolerances \u00b10.025 mm; length \u00b10.050 mm typical.<\/span><\/p>\nDoes Rapidcision hold ITAR registration?<\/b><\/p>\n
Yes. Rapidcision is registered with the US Department of State Directorate of Defense Trade Controls (DDTC) as an ITAR-registered manufacturer. All defense program technical data (CAD files, drawings, CNC programs) is handled under a Technology Control Plan that restricts access to US persons only. Rapidcision’s AS9100D certification covers its full CNC machining scope for aerospace and defense programs, and the company’s quoting engine routes ITAR-flagged programs to the secure program management workflow automatically.<\/span><\/p>\nWhat documentation is required for defense CNC components?<\/b><\/p>\n
Defense CNC orders typically require: Certificate of Conformance (CoC) citing all applicable specifications and confirming compliance; CMTR tracing the material to a specific heat lot with chemistry and mechanical properties; hardness test certificate (HRC or Brinell) for heat-treated components; dimensional inspection report (CMM report citing all drawing dimensions); surface finish measurement report for finish-critical surfaces; and any process certifications (heat treat record, finish process record). For munitions and ordnance, additional explosive safety review documentation may be required before the machining supplier can accept the order.<\/span><\/p>","protected":false},"excerpt":{"rendered":"Defense CNC machining operates under a regulatory framework that is fundamentally different from commercial or aerospace commercial machining: ITAR registration restricts supplier eligibility, AS9100D governs the quality management system, CMMC is emerging as a cybersecurity requirement, and military specifications (Mil-Spec) define material, process, and documentation requirements.
