The thing is that the job sheet is independent of the post selection, that is you can pull up the same job sheet regardless of what machine you want to use.
So it seems to me that the machining time should be a function of the CAD chain length multiplied by the feedrates.
I've tried many different values in the NC setup Machine rapid speeds and this value seems irrelevant at this stage, too. The job sheet gives exactly the same time, no matter what I put in.
Give you an example: I did a planar finishing pass at at stepover of .005 and a surface accuracy of .001. producing 47000 lines of code. This was clocked to be 6 hours and something.
Then, I redid the finish pass again at a stepover of .004 and a surface accuracy of .0005, producing 69000 lines of code, but the machining time is only 3.5 hours.
It sounds like some kind of a math glitch in the internal formula.
