Milling Time Calculator
This will compute the time an end mill to take to remove material based on feedrate,area, depth, cutter diameter, and depth increment.
This is used for pocket milling and face milling. Use the other calculators on this web site to calculate the feed rate.
The reason for the .65 default step over is that this is percentage of cutter that will not leave "posts" at direction change when zig zag milling.
