Special-process drift
Heat treat, welding, and CNC outputs need early warning before they become major or minor audit findings.
Aerospace
Traceable evidence for special processes and supplier lots.
Aerospace manufacturing demands documented control on tight tolerances and special processes — often under AS9100-style expectations. ProCalc supports the same floor toolkit your engineers use: SPC, capability, DOE, and disciplined problem solving — locally in the browser.
Industry pain points
Supplier lot approval
First-article and ongoing lot comparisons require defensible capability baselines on shared CTQs.
Escape containment
Nonconformances need fast clustering, supplier isolation, and corrective-action trails customers expect.
How ProCalc solves them
Control-plan-aligned SPC
Monitor hole diameter, surface finish, torque, and NDT results with charts your reviewers can follow.
Capability before release
Run studies and compare supplier lots on the same critical characteristics before production approval.
Investigation discipline
Defect maps, swap studies, and structured corrective action document the trail from escape to closure.
Example use cases
Special process & machining control
Catch drift on heat treat, welding, or CNC before it becomes a customer finding.
First article & supplier lots
Build a defensible baseline before approving production or releasing downstream assembly.
Escape & corrective action
Map defect clusters and document supplier vs. process causes for audit response.
