CNC machining time for a batch

Set these parameters: “Processing time per item”. In Numloom, enter “Number of parts to machine” (items) to obtain “Machining time” (min).

Calculations currently require access to Numloom on Google Play Internal Testing. iPhone and iPad support is planned.

How it works

Machining time = Number of parts to machine × Processing time per item ÷ 60

In Numloom: “Number of parts to machine” → “Machining time”.

items → min

Processing time per item · s/item

This page shows the formula and parameters. The calculation runs in Numloom.

Assumptions and limits

Calculation basis: “Number of parts to machine” (items) → “Machining time” (min). Use the parameters shown for this particular operation.

The estimate assumes the stated operation has a constant time or rate per item. Machine time and person-hours differ; setup, downtime and parallel work require their own measured allowance.

Enter a whole number of the items counted.

Coefficient sources

Initial settings: Processing time per item = 45 s/item (example in the original task description).

These starting values are not a standard, calibration certificate or manufacturer recommendation. Replace them with values measured for your process or specified for your product.
