FAQs

Quick answers about OptiStack's shimless tooling and fractional kit workflow.

Coil slitting software is used to generate buildable arbor setups from your coil width, slit pattern, machine presets, and real inventory. OptiStack Pro produces a top & bottom arbor stack map plus a BOM (assembly order list), so operators can load the setup without recalculating or guessing spacer combinations.
Slitter knife spacing is calculated by converting your strip widths and quantities into slit lines, then placing knife pairs across top and bottom arbors based on mechanical rules, clearances, and reserves. OptiStack computes this automatically using your machine presets and real spacer inventory, ensuring consistent and repeatable knife positions.
A slitter arbor setup is the physical build sequence of knives and spacers on top and bottom arbors. OptiStack generates a load-ready stack map showing exact positions, plus an assembly order list (BOM) for each arbor. The solver checks usable length, reserves, and strict inventory to ensure the result fits your machine and is physically buildable.
Yes. OptiStack generates an export-ready setup sheet with a clear assembly order list (BOM) for both top and bottom arbors. The sheet includes exact spacer widths, quantities, and where they go in the build—ready for print or digital reference on the shop floor.
OptiStack will not fake a setup. If your inventory cannot realize the required pocket widths within your tolerance band, it returns a blocking reason and a missing tools list (exact spacer widths and quantities needed). This prevents unbuildable setups from reaching the floor and saves operator time.
