Bending
Glintify detects every bend from the geometry, standard bends with grade, radius and axis, hem bends (150-210°), bridges and special bends. K-factor per DIN 6935 is calculated per bend, and a bend sequence is suggested to minimise collisions. Changeover time per tool change is added per batch.
What Glintify detects
The system analyzes the part's geometry and extracts every manufacturing-relevant feature without manual input.
Bend lines, angle, radius, axis direction, bend length, hem bends
What is calculated automatically
All measurements are extracted directly from the geometry.
Quality rules
The system automatically checks whether the part fits within your capacity and flags designs that can cause production issues.
Typical setup

Cost example
Line-by-line breakdown of the part cost using your machine data and prices.
| Cost item | Amount |
|---|---|
| Changeover 1 tool | SEK 38.00 |
| Bend 90° × 4 (2 m total) | SEK 6.40 |
| Total bend time (incl. changeover) | SEK 44.40 |
| Material DC01 2mm | SEK 18.50 |
| Total part cost (200 pcs) | SEK 62.90 |
The same routing line as in Monitor
On top of our time-based calculation, bending is also costed as a routing line ("beredningsrad") in Monitor's format: production group (work center), setup time, cycle time, allowance (F-time) and piece time, priced with the production group's cost factors. The line can be exported as an article with routing straight to your ERP system.
| Routing line | Explanation |
|---|---|
| Production group | Fetched from your ERP system or created from the machine park |
| Setup time | Per batch, not per piece — spread over the quantity |
| Cycle time | The technical time per piece, calculated from the geometry |
| F-time % | Allowance on top of the cycle time |
| Piece time | Cycle time × (1 + F-time %) |
| Cost factors | Machine, wages + social charges and fixed manufacturing overhead in SEK/h, with a staffing factor |
Markups for MO (material overhead), LO (subcontracting overhead), AFFO (general overhead) and profit are added at quote level — exactly as in Monitor's pre-calculation.
Bend radius, flange and hole distance in press braking
Guideline values for sheet metal bending in steel (DC01/S235) using air bending on a press brake. Glintify checks every bend in the STEP file against your own limits, this table is a typical baseline.
| Thickness t | Min inner radius | Min flange length | Min hole distance |
|---|---|---|---|
| 1.0 mm | 1.0 mm | 4.0 mm | 3.0 mm |
| 1.5 mm | 1.5 mm | 5.5 mm | 4.5 mm |
| 2.0 mm | 2.0 mm | 7.0 mm | 6.0 mm |
| 3.0 mm | 3.0 mm | 10.0 mm | 9.0 mm |
| 4.0 mm | 4.0 mm | 13.0 mm | 12.0 mm |
An inner radius below 1·t risks cracking and uncontrolled springback. A flange below 3·t does not span the die opening and requires special tooling. Rule of thumb: the V-opening is roughly 6–8·t in air bending, and the resulting inner radius is about V/6.4. Bending force grows with t² and drops with a wider V-opening, so tooling choice drives both the achievable radius and the required press tonnage.
Air bending, bottoming and coining
The method drives both tolerance and tonnage, and therefore cost per bend. Glintify calculates tonnage and setup time per method from your press brake and tool library.
Air bending
The sheet never reaches the bottom of the die. One tool covers many angles, which means fewer tool changes and lower setup time. The radius follows the die opening and springback must be compensated.
Bottoming
The sheet bottoms out in the die, giving repeatable angles and less springback. Requires tooling per angle and therefore more tool changes on mixed-angle batches.
Coining
The radius is coined into the material. Tightest tolerance and minimal springback, but high tonnage and tool wear, mainly used for small radii and tight requirements.
