What is the formula for calculating a bridgeport / lathe feedrate in Inches per Minute, when all you know is the RPM & .200/revolution of the leadscrew?
My bridgeport has a simple powerfeed on the x-axis, and no indication or divisions of how fast its moving? By experience, I can see & feel the feedrates, but have no idea what they really are!
IPM=RPM*.200 ?
