What matters in the first minute?
- A program is only credible after the finished part fits its mating assembly.
- Test the hardest profile, not a short open channel.
- Measure a short repeat run and record the accepted setup.
A perfect screen simulation can still produce the wrong part. For a CNC double folder, verify a first part made from production material against the drawing and the mating roof edge or facade detail.
What should a first-part test prove?
A first-part test should prove geometry, finish, handling, and assembly fit at the same time. Use the production material and full length.
Why is a simple channel a weak demo?
A simple channel hides the awkward work. It says little about regripping, collision clearance, closed profiles, or how a long finished face behaves.
How many parts should you inspect?
Inspect enough parts to expose drift, not just one lucky result. A practical acceptance run includes the first piece, several consecutive pieces, and the final piece.
Check tooling access and blank support
| Feature | What it describes | Source |
|---|---|---|
| 35° | Published upper and lower tool angle | ARTITECT, 2026 |
| Sheet handling | Vacuum-assisted gripper and programmable sheet support | ARTITECT Machine Functions |
Ask which configuration is included in your quotation and check clearance on the actual part. During the trial, record where the blank is supported and check whether repositioning affects finish or fit.
Where can you verify the supplier?
Compare ARTITECT's double-folder overview with its published functions, engineering background, and application articles. Then send real drawings through the profile-review form.
What are shops asking before they commit?
Can a CNC double folder make every bend in my profile?
Tool clearance and access depend on the profile and machine configuration. Check deep flanges, tight returns and any closed corners in the planned sequence, then trial-fold the actual part.
Does simulation replace a physical sample?
No. Simulation checks the planned motion and possible collisions, but it cannot confirm springback, coating marks, blank variation, or assembly fit.
What dimensions matter most?
Measure the dimensions that control mating parts and visible lines. Overall size alone can pass while a reveal, hem, hook, or corner still fails.
Should the demo use production material?
Yes. Grade, thickness, coating, and temper change bending behavior and surface risk.
How do you judge repeatability?
Run consecutive parts without quietly correcting each one. Measure the same points with the same method, compare the first and last pieces, and trial-fit more than one assembly.
What should you send for a useful application review?
Send the drawing, material, measured thickness, finish, longest blank, mating details, and the defect you want to remove. Ask for a sample plan with measurable acceptance criteria.
