How to touch off a tool on a 3-axis mill.

In this session I show how to touch off an end-mill and store the tool length offset it in the Tool Length Offset Page on a Haas 3-axis mill.

Tom, Thank you kindly for this information 😊

[@CADCAMCNCOFFICAIL]

I see your channel guide very rewarding, thank you!

[@JustMe-er9ve]

Thanks Tom, another great video.

Great breakdown!!!

[@tomasobamela]

As always.....There is something I re learn . I have a renishaw on a Mori Duracenter. Nice machine and a nice probe along with a tool probe . . I think I would have to watch this video to get back into a Hass.

[@tomasobamela]

It's also really educational that people like you Sir Tom , that take the time to put these instructional videos together. So we can all enjoy at our leisure. I thank you. Have a great day Tom.

tomasobamela Thank you very much for your comments. I appreciate it a lot. Have a great day! Tom

Does this work for multiple tools on the same operation? How would I go about setting the next tools? Do I just touch the top of the probe and record it in offsets? Will I have to att the same value or 5in to ever tool?

[@hemligagosta6554]

all of the work offset g's were occupied on your control, but another way to do it is what is called the g59 method, at least here in sweden, you put the setter on the table, gauge block on top of that, touch of the spindle nose and enter the value in g59 z, subtract the gauge block, remove them and touch of the tools on the setter and enter their values in the tool offset, you'll gett positive values, since it is the length of the tool that shows, when you're done with that, put the setter on top of the work piece and touch it of on the nose, enter value in g54 z, subtract setter, and you're done, if you haven't touched of x and y that is. i know there are people in usa that collects both ordinary and weird stuff, so i have to ask if someone approached you about that controller, it must be one of the first haas, or as it originally was called, haa5, with a request on buying it for their collection of controls.

Hi, I personally think, that positive tool offsets are better, because in the table real lengths of the tools are stored and you can easy compare these values to real dimensions of the particular tool. It makes pre-milling checking easier and there is less possibilty to make stupid mistake. Are you agree with me? Is it possible on your haas machine to use positive offsets?

[@TomStikkelman]

Yes it is possible. I think different shops adopt different methods and they all work. It all depends what you are comfortable with.

[@JohnathanSadler-ks5bk]

I don’t understand why we start with a -8 instead of a positive 8.

[@abdullahalbdaiwi7270]

good videos but it's easier to touch off tool hight with a piece of paper on top of my stock or sometimes I use an indicator with light. the indicator is 2 inches above my part

[@Beerbatter1962]

Ah, but that is the beauty of the touch probe method. When he puts a second or subsequent piece of stock in the vice, he only needs to touch off the top of the part once. All the tool offsets are still good and don't have to be redone, because they're all referenced to the touch off probe not the top of the part. So technically you only need to touch off all your tool offsets one time.

I set up Haas machines every day I set my spindle nut 500 above finnished thickness then set all my tools the same way 500 above Finnish thickness

[@jimfran2761]

Good video but it's so much faster to touch off on the work piece with a piece of paper. I would only do this if I had multiple work location with varying heights. But keep the videos coming . I'm learning a lot from you.

[@TomStikkelman]

Thanks Jim. I appreciate the feedback. Tom

[@Factory400]

I always touch off relative to the table since I want/need to use the tools for a variety of jobs and setups. The tool offsets are consistent regardless of what I am doing. My method varies slightly from Tom's, but basically the same. It is an excellent workflow. Quick, easy to explain to the newcomers, and hard to mess up going from job to job in a busy shop.

[@Trendyrapslut]

then it's only good for one part

[@neilkitzler9268]

the downfall to this method is if you break a tool or a tool chips or crashes. you are unable to touch the top of the workpiece off after the cuts
