Machining Inches per Revolution

on . Posted in Welding Engineering

Machining inches per revolution, abbreviated as IPR, is the distance in inches that a cutting tool travels for each revolution of the workpiece during a machining operation.  It is a critical parameter in machining processes and is used to determine the feed rate of the cutting tool.  By adjusting the feed rate and spindle speed, machinists can control the IPR to achieve optimal cutting conditions for different materials and machining operations.  Optimizing IPR is crucial for achieving desired surface finishes, extending tool life, and improving overall machining efficiency.  Different materials and cutting tools may require specific IPR settings to achieve the best results

 

Machining Inches Per Revolution formula

\( IPR =  IPM \;/\; RPM \)
Symbol English Metric
\( IPR \) = inches per revolution (feed rate) \(in\;/\;rev\)  
\( IPM \) = inches per minute (feed rate) \(in\;/\;min\)  
\( RPM \) = revolutions per minute \(rev\;/\;min\)
