Fusion Post Processor Testing & Validation
A post is only as good as its testing. We validate Fusion posts with test part libraries, output comparison, machine simulation, NC verification, dry runs and supervised machine trials, so you can trust every program that leaves Fusion.
Catch problems before they reach the machine
Many post problems only appear in certain situations: a specific cycle, a rotary near its limit, a tool change after a tilted plane, an arc across quadrants, or a rarely used option. Testing one or two parts does not cover them. When a post is new or changed, a structured test plan is the difference between confidence and a crash.
ENGIMANDI validates Fusion posts with a test library of Fusion documents covering every operation type, cycle and option your machine uses. We compare output against approved reference programs to catch unintended changes, run Fusion machine simulation, back-plot the NC code in independent verification software where needed, and plan dry runs and first cuts with your operators. You receive a test report and the library to re-run after future changes.
Read how to validate and test a CNC post processor, post processor verification before CNC and back-plot simulation and NC code verification.

How we validate posts
Layers of checking.
Test Library
Fusion documents covering every operation, cycle and option.
Output Comparison
Diff against approved programs to catch unintended changes.
Machine Simulation
Fusion simulation with your machine model and limits.
NC Verification
Back-plot the actual G-code in verification software.
Edge Cases
Limits, rewinds, tilted planes and rare options.
Machine Proving
Dry runs, single block and first cuts with your team.
Validation tools
Fusion and independent tools.
Typical projects
- Validating a new 5-axis post before production
- Regression tests after a Fusion update
- Checking a post from another supplier
- Test plan for a new machine installation
- Quality records for aerospace customers
- Proving a post without machine access

Testing & validation questions
Is Fusion simulation enough?
It is a strong check, but it simulates the toolpath with a machine model. Verifying the actual NC code adds another layer of safety.
Can you validate a post you did not write?
Yes. We review and test posts from any source.
Why re-test after updates?
Fusion and post updates can change output. Regression tests catch this quickly.
Can you test without our machine?
Much of the testing can be done remotely. Final proving is done with your operator.
What if tests find problems?
We fix them, or see debugging and error fixing.
