Inspection Software
Off-line programming and inspection planning platforms that let you write, simulate and validate measurement programs from CAD - independently of any single hardware vendor.
How it works
Inspection software takes a CAD model (with or without PMI), an inspection plan and a measurement device model, and produces a validated measurement program that can be run on the shop floor. Modern platforms simulate probe paths, check collisions, and generate ballooned reports linked back to drawing features.
Typical accuracy
Programming quality does not change the CMM's MPE, but it dominates real-world uncertainty via probing strategy, alignment, sampling and datum construction.
Applications
- Off-line CMM and scanner programming from CAD
- Collision simulation and cycle-time estimation
- Feature-based reporting linked to drawing balloons
- First-article, PPAP and AS9102 report generation
- Fleet management of measurement programs across multiple sites
- Version control and central program library
Strengths
- • CMM time is expensive - off-line programming reclaims it
- • PMI-driven programming reduces drawing interpretation errors
- • Central program libraries protect against operator turnover
- • Same platform across CMM, scanner and portable arm reduces training
Limitations
- • Requires disciplined CAD/PMI hygiene from engineering
- • Simulation is only as good as the fixture and stylus model
- • Some platforms are tied to a specific hardware vendor
- • Licence and training costs add up in multi-seat deployments
Vendor-tied vs hardware-neutral platforms
PC-DMIS, Calypso, MCOSMOS and MODUS are closely tied to their parent hardware. PolyWorks and Verisurf are hardware-neutral and can drive multiple brands from one seat. Neither approach is wrong - but the decision has long implications for training, licensing and multi-site standardisation.
PMI-driven programming
When engineering delivers CAD models with proper product manufacturing information (PMI) attached, inspection software can generate 60-80% of a measurement program automatically. The bottleneck is almost always PMI discipline in CAD, not the metrology software itself.
Buying considerations
- CAD import range and PMI fidelity
- Hardware neutrality - can it drive your existing and future devices?
- Simulation depth: probe changer, rack, fixture, collision
- Report templates matched to customer requirements
- Central program management and version control
FAQs
Can we program off-line without the CMM?+
Yes - a laptop and a CAD model is enough for 80% of the program. Final touches (probe angles, real-world collisions) are done on the machine.
How long does it take to become productive?+
For an experienced CMM programmer moving to a new platform, 1-2 weeks of guided use. For a new starter, 3-6 months to real independence.
