CALCULATORS BY INDUSTRY

Machining calculators

Relate entered cutting speed, RPM, feed, travel, removal and cutting-force assumptions.

Batch Completion Time

Estimate whole batches and synchronized parallel waves using one elapsed setup delay and a full cycle for every partial batch.

Use batch completion time →

Cutting Speed & Spindle RPM

Convert an entered surface speed in metres per minute and effective cutting diameter in millimetres into rotational speed.

Use cutting speed & spindle rpm →

Milling Feed Rate & Travel Time

Multiply entered RPM, effective teeth and chip load, then estimate ideal feed-travel time for a defined path and number of passes.

Use milling feed rate & travel time →

Milling Material Removal Rate

Rectangular-engagement removal rate in cm³/min = axial millimetres × radial millimetres × table feed in mm/min ÷ 1,000.

Use milling material removal rate →

Turning Material Removal Rate

For the stated turning relation, material removal in cm³/min is surface speed in m/min × depth of cut in mm × feed in mm/revolution.

Use turning material removal rate →

Before you use these calculations

Use the effective cutting diameter and engaged teeth for the operation.

Enter tooling and material parameters supported by the supplier or your measured process.

Ideal arithmetic excludes machine limits, rigidity, wear and setup constraints.

Start with the example, replace the assumptions with your measurements, then change one input to see its effect. Save or export the scenario if you need to keep its basis.
