Excellent that how I do it but with gauge blocks instead. It would be helpful if you showed rotating the tool by hand and checking all cutter edges. Very few are exactly the same and you need to find the lowest cutting edge. This is the runout to the cutting plane of the tool itself. I have seen as much as .014" on a face mill.
I measure my tool offsets with a Blum laser. To get the stock offset, I use a 3x optic and touch off the stock in increments of 0.010 mm. Sometimes I will rotate the tool with my finger, if it clears the Sharpie marker, then I am within -0.001 mm to -0.009 mm. Last, I face 0.040 mm to 0.100 mm off the top, and call that new offset the top of the stock. Now I should be within 0.001 mm.
I'm enjoying your CNC Mill Fundamentals series. I'm just getting started and I have a newbie question. Why measure first with the puck then update the offsets? Why not just measure off the 1-2-3 block? It seems like an extra step, but I'm sure there's a good reason you do that and it would be nice to understand why. Thanks!
So, in the video we explained that, the fixture is best... but since there was a negative number in Z... it could be confusing to a new student so we chose option B so you could clearly see 6.0 offset. There was a Z in G54 because the machine had been probed.
The easiest way to manually input tool offsets would be to use a pre setter, a relatively in expensive piece of equipment and easy to get hold of, or even a height gauge and a couple of blocks, i would only use this technique if I had no choice
Why you're doing it by moving the spindle up and not down? I was thinking that while machining the movement is down towards stock and measuring that way will eliminate whatever backlash or flex in the machine might be.
I use a datum tool something like a spot drill that is set to zero in the tool offsets then i use a piece of paper to set all the other tools according to datum tool. paper is 0.05mm so i bring the tool untill i feel it touch the paper then move the tool down 0.05mm and set the z but i think using this method could be more accurate
Hmmmm. I guess that is assuming all of your inserts are all seated properly, your shell mill is exactly square to that plain. And the seats are exactly the same.....
I have a question about the American measurement system, since Brazil uses the metric system, and in the US it uses English! Do machines convert measurement systems?
Proper way. Put a tool presetter on table, touch it of with spindle, write down value in machine coordinate and write that number down. Put in your tool, zero it on presetter, press tool measure and add value that wrote down before. BOOOOM done
let me preface this by saying I am a machinist.I think I could learn a lot from Titan.maybe I am being just too picky but if he touched that off you should have torqued it the same way you did the part.

nicely presented man.. thats effort right there. good kid
Great video! What's your opinion on subtacting the whole g54 .250 instead of every tool? Are there any minuses for this? Thanks

Great video. Do you purchase or make your 1/4 inch pucks? If you purchase them, where?
Can you show how to set tool heights with a probe and a height gauge indicator?
That's a separate video that can be found on the academy.titansofcnc.com

How accurate can this be for your average joe?
What was the point of adding the -0.250? If you used the same method with every tool, as you should, the .250 would make no difference.

Young man, we say "We are ready to make some chips", not "cut" some chips. Titan nut gonna be happy if you re-cut da chips ;)
Good vid, thanks!
Thank you

This could be a commercial for Renishaw and Blum. Manually touching off tools is MORE expensive than the common electronic tool and work probes.
I have a new 1 2 3 block ...that i had quality control check....easier to use just the 1 inch.
I have a question about the American measurement system, since Brazil uses the metric system, and in the US it uses English! Do machines convert measurement systems?
Yup they sure do
Why would you teach anyone to do it this way? Wouldn't it make more sense to pick up each tool to the table?
Many different ways, this was a basic technique used for our teaching series, Building Blocks... located at academy.titansofcnc.com
Proper way.
Put a tool presetter on table, touch it of with spindle, write down value in machine coordinate and write that number down.
Put in your tool, zero it on presetter, press tool measure and add value that wrote down before. BOOOOM done
I trust no-one that wears a hat backward. :-)
Lol
