CMM Inspection Services for Aerospace Parts
Coordinate measuring machine (CMM) inspection is the backbone of dimensional verification for precision aerospace and defense CNC parts. Olympus Machining LLC operates two CMMs in our Hanover, Pennsylvania facility: the Haas HMM 430 (3-axis manual/CNC measuring machine) and the Chien Wei CWB-450-CNC (full CNC CMM). Both are used for in-process inspection, final inspection, and AS9102 First Article Inspection on ITAR-controlled work under our CAGE 9V9P0 supplier code.
Equipment
Haas HMM 430
3-axis CMM with a 400 × 300 × 300 mm measuring envelope. Used for prismatic parts, brackets, housings, and milled features. Touch-probe measurement of linear dimensions, hole patterns, position tolerances, flatness, perpendicularity, and parallelism. Programmed in PC-DMIS-equivalent CMM software with results exported to AS9102 Form 3.
Chien Wei CWB-450-CNC
CNC coordinate measuring machine with a 450 × 500 × 400 mm measuring envelope and rotary axis support. Used for turned parts, complex 5-axis milled geometries, and components requiring repeatable cycle inspection across production lots. Capable of true-position evaluation, profile of a surface, cylindricity, and coaxiality on shafts and bores.
When CMM Inspection Is Used
- • AS9102 First Article Inspection (Form 3 characteristic accountability)
- • Production lot dimensional verification on aerospace and defense programs
- • In-process inspection between operations on multi-setup parts
- • Source inspection support when a customer representative attends final acceptance
- • Capability studies (Cp/Cpk) on production runs requiring statistical evidence of process control
- • Reverse engineering of legacy parts when only a sample exists
CMM Reporting Standards
Olympus Machining issues CMM inspection reports compliant with AS9102 Rev. C (aerospace First Article Inspection), ASME Y14.5-2018 (GD&T), and customer-specific PPAP requirements. Every report includes operator ID, machine ID, calibration traceability, measured-vs-nominal data with deviation flags, and digital sign-off. Reports are exportable as PDF or CSV and archive-retained per our document-control procedure.
| Standard | Use case | Turnaround |
|---|---|---|
| AS9102 Rev. C FAI | New aerospace part numbers; Forms 1, 2, and 3 | 24–48 hr after first article off the machine |
| PPAP Levels 1–5 | Tier 1 / automotive flow-down requirements | Per customer specification |
| Custom dimensional report | One-off precision parts, source inspection | Same-day for in-spec parts |
| SPC / Cp / Cpk study | Production runs requiring statistical evidence | Run-end summary |
What's included in every report
- • Job number, part number, revision, drawing reference
- • CMM machine ID, calibration date, operator ID
- • Each feature measured: nominal, tolerance, actual, deviation, pass/fail
- • GD&T callouts referenced to ASME Y14.5-2018
- • Traceability chain to NIST-calibrated masters
- • Document-controlled sign-off
Documentation Output
CMM measurement output is delivered in the format the customer requires — most commonly an AS9102 Rev. C Form 3 with balloon-numbered characteristics, but also as a customer-template inspection report, a generic dimensional report, or raw CMM output (when requested for the customer's own analysis).
For ITAR-controlled parts, dimensional reports are handled as controlled documents under the same procedures as the engineering drawing — stored in access-controlled folders and delivered through customer-specified channels.
Calibration and Traceability
Both CMMs are calibrated annually by an accredited calibration service. Calibration certificates are NIST-traceable and are made available on request as part of supplier qualification packages or audit responses. Inspection-relevant hand tools (micrometers, calipers, gage blocks, thread gages) are managed under the same calibration program with controlled recall intervals.
Add CMM Inspection to Your Order
CMM inspection is included by default on AS9102 first articles and available on production runs as a quoted line item. Submit your drawing with a note of the inspection scope you need.
