I like Infinity QS because they are able to generate the
X hi/lo-R chart that is most appropriate for CNC machining. You can see how to do it
here. They can also do many other charting methodologies, such as Xbar-R and I-MR when they are appropriate. They really should not apply to CNC, though, unless you are doing low tech wood or plastic machining.
I have never been able to get Lighthouse to do X hi-lo/R charts - but the last time I tried to use them was quite a few years ago.
