Neway's ability to handle Production Part Approval Process (PPAP) documentation and first article inspection (FAI) reports must be verified for each automotive program; this page alone does not establish that capability. Before award, require a scope-matched deliverable matrix, responsible owners, permitted sample records, and written acceptance of the customer's quality agreement. The matrix should name the submission level, customer-specific requirements, FAI template, drawing revision, special characteristics, sample quantity, timing, approval authority, and exclusions. Confirm that each promised record will come from the proposed CNC machining service route and its approved outside processes. Hydraulic bodies, shafts, brackets, and sealing parts may need different dimensional, material, functional, and traceability evidence within one vehicle program.
PPAP and FAI answer different approval questions. An automotive PPAP submission provides evidence that the defined production process can meet customer requirements under its planned controls. Depending on the requested level and customer-specific rules, the package may include process flow, PFMEA, control plan, measurement-system analysis (MSA), dimensional results, material records, capability studies, samples, and a Part Submission Warrant (PSW). FAI checks a production-representative part or batch against the released drawing and records each result, method, instrument, and disposition. An automotive FAI format may be customer-specific; AS9102 should not be assumed unless the contract requires it. Under AIAG PPAP, Level 3 is the default submission level unless the authorized customer representative specifies otherwise. The matrix must also state whether appearance approval, checking aids, master samples, packaging evidence, IMDS-related data, or open concessions are required. A dimensional pass cannot replace a missing approval record.
Machining evidence is valid for PPAP or FAI only when the sampled route represents the intended production process. Critical features may come from precision machining services, interpolated and datum-related features from CNC milling services, and shafts, ports, or threads from CNC turning services. Early CNC machining prototyping can resolve datum interpretation, gauge access, tool-life risk, and inspection feasibility before submission. Prototype evidence needs a documented bridge when temporary fixtures, manual deburring, substitute material, or different inspection equipment were used. Production representation depends on the released program, fixture concept, gauge method, work instructions, control plan, and qualified personnel. It does not require the same individual operator to make every approved lot.
Surface requirements need evidence separate from ordinary dimensional results. When a drawing specifies an machining surface finish, the report should identify the feature, measurement direction, cutoff or evaluation setting when applicable, instrument, and acceptance limit. Recording only an Ra value without location or method leaves the result ambiguous. If appearance, corrosion protection, coating thickness, or masking is specified, a defined CNC part painting solution requires its own process record and inspection point. A finish change after approval may affect bores, threads, datums, sealing faces, or fit and can trigger customer review or resubmission. A bore may pass diameter inspection while its sealing function remains unproven because roughness, burrs, coating buildup, or a masking edge is a different acceptance characteristic.
Material choice changes the records needed for an automotive submission. The same package cannot be copied unchanged across hydraulic or chassis parts in Stainless Steel (SUS304), shafts in 1045 steel, housings in Aluminum (6061), valve bodies in Brass (C360), or functional bases in ABS. The drawing and customer rules determine whether material certificates, heat or lot traceability, resin batch data, heat-treatment records, coating certificates, regulatory declarations, or functional tests are required. The submission should connect each record to the sampled parts rather than provide unrelated supplier certificates.
For Automotive braking, steering, e-mobility cooling, and fluid-control programs, documentation should expose production risk before launch and preserve the approved revision afterward. Similar controls may be contractually required for Industrial Equipment entering an OEM supply chain or Consumer Products that use customer-defined automotive methods. The control agreement should name the owner of drawing release, special-characteristic review, sample retention, nonconformance disposition, and change notification. It should also define which changes require notification or resubmission, including material source, fixture, CNC program, inspection method, outsourced finishing, or production location. Without those triggers, an initially complete package can become disconnected from the process that later makes the parts.
The RFQ should request the PPAP level, FAI template, drawing and CAD revisions, special characteristics, planned annual volume, sample labeling, measurement format, and submission deadline. It should also state whether MSA, Cpk or Ppk studies, material certificates, calibration evidence, appearance approval, packaging validation, IMDS-related information, or customer forms are mandatory. For every capability study, the buyer should define the characteristic, sample plan, acceptance rule, and reaction when the trend approaches a limit. Before award, require Neway to return a responsibility matrix showing each deliverable, source record, approval owner, timing, exclusion, and evidence status. Do not treat an unchecked matrix item as accepted capability. Production approval remains tied to the exact revision, process route, material controls, inspection method, PSW or customer sign-off, and any open deviation. Only the resulting written scope and returned evidence can support a program-specific capability decision.
