In a low volume/high-mix job shop or a prototyping shop - tool life is nearly impossible to track by any method. Reducing setup time and crashes is the primary focus. I used a 'ping pong' method for years where we had double the tool holders and double the workholding so that we can be prepping a job with tools and fixtures while another is in the machine. Drastically reducing changeovers. The Pro Pallet systems are the ultimate way to change over machines for totally different parts/materials/tools a number of times in a single day.

Another good one 👍 Hope you'll release that video about tool cards soon as this is one of the subjects on my table for the next quarter. Thanks again for all the priceless contents 🙏🙏🙏
We use Okuma and Mazak machines. They are equipped with collision detection system. You just model your tools, workholding, your blank and part (import from CAD) and voila, the machine won't let you go any closer than 3mm to any of these. Except of blank and part. This is really good for 5ax simultaneous machines where it's very easy to crash machine itself. It needs some effort, but if you make some automatization of model generation it really worth a penny.
Love the Q&A videos, but what happened to the last robot video? At the end of the last one you mentioned a video showing the final setup and use. Hope that’s still coming!
If I am not mistaking, Doosan has only Fanuc control and there you can set max and min load for every tool, and min load is for example: if your load is 0% for more then 2 seconds it stops because it thinks that insert is broken. It is a little bit complicated but not if you are gonna use it a lot and save your self a lot of time and collisions.
Can you tell us how you select mitee bite clamps and the quantity of them for particular operations on a fixture with regards to tool feed and cutting forces. With multiple sizes and clamping forces, do you have a schedule of ranges for radial depths of cuts for particular clamps. I don't have any experience with the clamps and it seems that it would be expensive and time consuming to find out by trial and error which clamps are best for particular roughing and finishing operations. Another aspect to using fixture clamps, do you program to the clamp capacity or do you select the clamp to match the program cutting parameters? Maybe some combination of both?
You did some great videos with NYC CNC on how you manage tool life, and how you standardise origins - you should link to that in the description. Great video BTW
I teach my employees (and practice myself) methods that will catch bad Z offsets or other mistakes for the initial setup. Sure it slows things down a bit. But problem with trying to rush through a setup is that it leads to costly mistakes.
@@PiersonWorkholding Sounds like a little BS going on here.... I will have to look thru mine tomorrow. I bet you are still laughing thinking about how many people you can get to do this.....
I put my job up on the machine when I left at the end of the day. It was not on the machine when I returned in the morning...the tool that was in the spindle was not there and the heat shrink tool holder melted at the bottom in such a way that it could not be used anymore
Unfortunately, some people live sad, sad lives where the best part of their day is clicking a thumbs down icon. Fortunately, they're only 1% of viewers.
1:28 . I just paused to see what tool do you use to examine a drill. and WHAT did i see? well ,I dont know that it cant be done.so I have to try it tomorrow.
@@PiersonWorkholding interesting. I've never saw a spinning cycle for this. Usually setting new and therefore clean tools but I'll will make sure the SPINDLE probe is clean when touching off with it even though it's tucked away and shouldn't be dirty. Although unless you're doing in process measuring and then a spinning probe could push chips away to achieve highest accuracy as possible. I just would think that a spinning tool is no beuno against a calibrated unit such as the tool setter. But interesting nonetheless even though Ive never saw this type of probing cycle on our Haas or Mazak but will be exploring it when I go back on tuesday!
to rebut/reply to myself after a few moments of thought, spindle probe is plastic tipped most likely softer than anything it touches so that's not good, and there is a possibility of touching off harder tools than the tool setter (which is carbide and harder tools that such as pcd or diamond coated(maybe not you but I have used both) so I definitely wouldn't want those spinning when touching the tool setter. We could make the argument that it's all relative but it is not if you have two different probes (tool setter and spindle probe) so if the tool setter wears down it's relation to the spindle probe would change over time. I'm just thinking in reliable terms over time/ways that relationships could change over time introducing tolerance issues when the two's relationship shall never change. The less variables the better, right? I understand it could be a while before it's noticed or even become a problem depending on other processes, but it could be something down the road. and that's enough for a discussion point from me-not to be a nay-sayer or to say you're doing it wrong but more as for discussion to garner perspective or maybe overlooked points.
@@cobburn I highly doubt any wear will ever occur. First off, the tool only spins backwards in the probing cycle. Second, regardless of tool/probe hardness the pressure it touches is incredibly light. Finally, people a lot smarter than me created this a long time ago so I'm sure they got it right. So how do you touch off face mills without spinning the tool?
@@PiersonWorkholding I thought the same that it is light pressure and spinning slowly. Diamond coated tooling isn't directional. and now you have softer tools against something harder albeit slowly and backwards. I just never saw it as our renishaw probes and macros only orient the spindle so this is intriguing to me. maybe it only spins for a face mill? I know the drill macros don't. my toolsetting pad has a divot in the middle of it actually I assume from many years of nonspinning use. smart people have gotten plenty wrong and it's not always about intellect. And smarts doesn't mean common sense. Internal bureaucracy can play a role or a change goes unnoticed. Look at Boeing, smart guys there huh and look where their MAX is. A company you'd think knew what they were doing. Things get compartmentalized and budgets for R&D get used up. Im not trying to be a dick and say what you're doing is wrong. It's a discussion and Im learning as well. It just looks really bad when it's on paper. No such thing as stupid questions right? I touch off a face mill like I would a big end mill, step it over and touch it off where an insert is. maybe it's just the face mill macro that spins? now i Have more questions and why I always ask questions. i'm naturally curious and it's not to point out any little thing. Learning goes both ways.
How to avoid crashes? Can't be done. You can reduce the number of crashes. Single block. Read program and know where it will be heading next. Get comfortable with switching between absolute position and distance to go.
"Never crashed a lathe". Hold my beer.
😂😂😂
HAHAHAHA
Need to run one first.....

Very insightful.. your q and a is a discussion that every machinery should hear.. thank you.
Thanks for your videos! I'm new to all this and they are super helpful. I hope you'll make more fixture fridays!
I don’t have a HAAS but great video. I go over my program about 5 times and pray I got it right.

Did you just look at a drill throug a refractometer? Reversed 😂
Don't laugh until you try it!

The haas atm function is how you get your money out the machine you just need your debit card and pin number
7:14 thats exactly what happens to me sometimes when i sleep. Even when i turn off the whole machine it still moves and stuff
Were you using a refractometer to inspect the end of a tool?
Yes! Machinist tip: You can use the lens of a refractometer to inspect drills. It doesn't work with endmills though.

@@davids.682 lol
Well spotted.
I was thinking the same thing ????
I put my job up on the machine when I left at the end of the day. It was not on the machine when I returned in the morning...the tool that was in the spindle was not there and the heat shrink tool holder melted at the bottom in such a way that it could not be used anymore
7:57 do you ever miss the button and the edge of the button goes under your finger nail? Thats what happens to me :P
The doosan has the spindle load function to it is self learning i use a lynx 200 lmy
Not a machining question but I like your black shirts. What brand are they?
Hanes Tagless or Hanes Beefy-T. Basically whatever there's not a supply shortage of.
very helpfull thanks
How do you justify a thumbs down to that? It's better then the videos you're not making🤔😒
Unfortunately, some people live sad, sad lives where the best part of their day is clicking a thumbs down icon. Fortunately, they're only 1% of viewers.
I had a dream where a 45mm U drill, went crash into the work bed and drill a hold on a new vf2ss
Please bring your lathe guy to your video and have him explain how o avoid crash on lathe. Thank you.
1:28 . I just paused to see what tool do you use to examine a drill. and WHAT did i see? well ,I dont know that it cant be done.so I have to try it tomorrow.
Make sure you don't point the lens directly at the drill tip or damage may occur.
@@PiersonWorkholding i have been doing it the wrong way for all my life
I'm just curious as to why the tool was spinning when touching the tool setting probe?
Using the rotating tool probing cycle is a good habit. It spins off chips that might be stuck to the bottom of the tool.
@@PiersonWorkholding interesting. I've never saw a spinning cycle for this.

Oh yes you can, if your good as me! I've been running my VMC for 3hrs 27minutes and 43seconds. Ain't crashed yet!
Damn it!!! %$#@@÷ Y'all had to bring up crashes. It's your fault I just screwed up my perfect record. 😁
@@aoiattentiononinvention8031 But you did reduce the number of crashes by 3 hours and 27 minutes. Be proud.
