Use this engineering calculation for a transparent preliminary estimate or independent arithmetic check when geometry, materials, loads, operating conditions, and units are defined consistently.

Feed Millimeters Per Tooth (mm/tooth)

Required number input.

Teeth

Required integer input.

Speed Rpm (rpm)

Required number input.

Milling table feed rate from feed per tooth, cutter flute count and spindle RPM. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Millimeters Per Minute (mm/min)

The resulting millimeters per minute returned as a number.

• Cutting speed and drilling time are nominal planning values. Tool material and geometry, workpiece machinability, feed, depth, coolant, rigidity, acceleration, chip evacuation, wear, and setup time determine practical cycle time and quality.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check assumptions against drawings, measurements, current material data, and the applicable design code. Apply required load combinations and safety factors, then obtain qualified review and testing for consequential designs.

• Milling Removal Rate

  Milling material removal volume per minute from radial engagement, axial depth and table feed.

• Cutting Speed

  Cutting surface speed in meters per minute from rotating tool or workpiece diameter in millimeters and spindle RPM.

• Drill Time

  Ideal drilling feed time from hole depth plus approach, feed per revolution and spindle speed; excludes tool changes.
