    Very handy calculator
  

*by B***D on Reviewed in the United States on December 10, 2011*

As an engineer, I am programming and setting up new jobs daily. Feeds and speeds are nearly an art than a number you can get from a book. Each insert grade, material type, hardness, type of cut, type of machine all play factors in feed and speeds. The Machinery's Handbook can give you an estimate on what it should be but after you run the part adjustments are usally needed. Watching and listen to the cut is really where you dial in the correct feeds and speeds. Vendors usally have a closer estimate than a handbook. That said, putting a table for feeds and speeds for every situation is impossible. I can't not fault this calcuator for not having a chart do to this.  As for the other features, I thought this calculator has plenty of them. I won't go threw all of them but one thing I like to mention is its ability to store certain data. I will give you an example: If I wanted to calculate an RPM in need to enter a diameter and Cut Speed (SFM). Say a decide that I want to increase my SFM; I can go back and re-enter the SFM and the calulator will update the answer. I can even re-enter the RPM and the SFM will update as well. I do not need to erase and start from scatch because the other information still resides in it. I can erase it all by pressing the ON button twice.  This calculator is very handy and I can't see why anyone would give a bad review. I think this calculator was well thought out and works great. The price is a bit steep but anything that is specialized typically is. I highly recommend this item.

    Great for routine tedious calculations in the machine shop
  

*by P***K on Reviewed in the United States on September 22, 2016*

This calculator does all calculations involved in conventional machining including pre-programmed standards for tap, drill and threads. It does not however have recommended cutting speeds as noted by other reviewers. So it's a good idea to have a machinery handbook or ready reference handy for this as well as if you need info on the aforementioned standards. If you're a design engineer or into prototyping you'll probably need at least an engineer's advanced graphing calculator or appropriate software for your laptop. This is of limited value for calculations of complex geometries. There is a newer version out now which does have material data-cutting speeds and I would most likely rate that a 5. For what it does it's a handy tool.

    Best Plastic Brain Any Machinist Could Wish For
  

*by C***E on Reviewed in the United States on December 8, 2011*

I have only just got my head around most of the features available on this device and in the short time I have been using it I have wondered how I managed without it. The threading data alone has proved most useful and has negated many wasted trips across the shop floor to look at charts. The Zeus book has become all but redundant however Machinery's Handbook still has its place. The trig functions have proved their worth as have the speed and feed calculations. I have read that one of the shortcomings of this calculator is the lack of material data relating to cutting speeds but with new cutting tools coming out a lot of this information would be redundant in no time. I have used this calculator for turning, milling, drilling, reaming and grinding and all these processes require different parameters that are easley handled. This calculator has proved its worth in the time I have had it.
