Feed Rate Calculator
Convert strokes per minute and progression into feed rate, throughput, and material consumption.
Using this calculator responsibly
The Feed Rate calculator is an engineering aid for checking a shop-floor estimate before a setup, quote, or process review. Enter values in the units shown, confirm material properties against the applicable specification, and keep a record of the assumptions used. Calculator output does not override machine capacity, tooling limits, part requirements, or a qualified engineer's approval.
Before using a result in production, repeat the calculation with the extreme values allowed by the print or process window. Check that the selected material, thickness, geometry, and safety factor reflect the actual job. If a result approaches a press, die, fastener, or machine limit, stop and verify it with the equipment manufacturer or responsible engineer.
Inputs and results
Read every field label before entering data and avoid mixing inch and metric values. A useful result should be traceable to the job number, revision, material certification, and machine or tooling record. Treat warnings, invalid ranges, and unusual outputs as reasons to inspect the inputs rather than as values to work around.
Feed rate is how much material the feeder advances per minute — the progression times the press speed. It drives throughput and material consumption.
Formula: Feed rate (in/min) = Progression × Strokes per minute
Worked example
- Progression 1.25 in at 120 strokes/min.
- Feed rate = 1.25 × 120 = 150 in/min, and you make 120 parts/min.
