The material determines density and machining reference values. Check the supplied condition.

Select the shape of the purchased stock.

Finished dimension along the stock axis. Verify any value suggested from the file.

Finished width of rectangular stock across its length.

Finished thickness of rectangular stock; enter this separately for a DXF drawing.

Largest outside diameter for round stock.

A closed STL mesh can provide the volume. Without a volume, material-removal time remains an assumption.

Initial value: 2 mm. Adjust it to the actual stock and workholding plan.

Setup and programming are spread across this quantity.

Selects the model used to estimate machining time.

Optional measured time instead of a material-removal estimate. G-code analysis does not simulate a controller and does not include every auxiliary time.

Affects reference values for auxiliary time, setup, and programming; it is not an automatic feature inspection.

Initial value: 2. Each additional orientation increases setup and handling effort.

Actual number of holes per part; this cannot be detected reliably from CAD files.

Representative diameter for the simplified drilling-time estimate.

Representative hole depth; check approach and overtravel.

Initial value for the approximate material-removal rate.

Effective number of teeth on the intended milling cutter.

Initial value: 0.45. Share of the theoretical material-removal rate, with interrupted cuts represented approximately.

Enter the current purchase price. The app does not invent a market price.

Initial value 0: add separately purchased cutoff or sawing costs.

Enter coating, heat treatment, and outside work from a supplier quote. Enter 0 explicitly if none applies.

Use an existing internal rate or estimate it from the machine costs below.

Example value including employer costs; replace it with your own internal rate.
