Kind of. Volumill will adjust the feed-rate based on external/internal arcs. Mastercam has a modifier in the filter in 2018, in the 2d contour tool paths to adjust the feedrate on arcs, I did not see it in any of the Dynamic tool paths however. I still think machines achieving the actual programmed feedrate is more of a problem than not adjusting the feedrate for Arcs. One extremely talented guy on here was working on a post to make the adjustments for arcs, but Mcam doesn't really have it supported IMHO.
I think that is solely dependent on what features are being cut. I would be interested in where the 27 percent came from. A boss will have less air cuts if the stock is symmetrical than compared to the same boss when the stock is not even on all sides. Ex. a rectangular boss out of rectangular stock vs. a square boss out of rectangular stock.
2017 comes with a pretty good post. There were issues with fwd/reverse live tooling calls and canned cycle issues in earlier versions of the "free" post. I personally would not by a post if you are using 2017, but it depends on what type of work you plan on doing with it.
Generic Haas ST 4x MT lathe
Yes, if setting 23 is off, then you can bring in a O9xxx program. However, it is bad practice to use 9000 programs as part programs, as they should only be used for macros.
This is incorrect both work
Haas requires .2 above the hole to give the spindle and z axis time to sync. Also, if you are tapping the same hole more than once, then the "repeat rigid tapping" setting must be on.
Everything FANUC, my default is .05 above the hole.
Under 1/8 diameter Titex drills, easy +/- .001 on Aluminum. When you are doing hundreds of thousands of 2-56 and 0-80, way too much time lost reaming.
Job I did with a .026 titex drill, +/- .0005. Every hole was checked. Few thousand or so holes now.
Decent keyless chucks or collets. And checking runout is key.
Is your work offset the center of rotation of the trunnion? This is a must for using inverse time on a table/table.
The units for Inverse time is actually time. The whole premise is that you are using similar units of all axis, which is time. The other big factor in the calculation is how long the line length is from point A to B.
Unit conversion for inverse time
Distance between point A and B / Feedrate =time
Units for time inches/ (inches/min)= min
Take the inverse of the time it takes from point a to b
1/time=inverse time feedrare
Units for inverse time 1/min=min^-1
