General Mach Discussion / Re: Auto tool zero - touch probe - please help

« on: October 04, 2008, 11:59:09 AM »

hey fellos sorry for not understanding the question to good I am just a newbe
but as far as a can tell on the tolerance as long as I set all the tools to the same hight with the drill stop attached. and also when you are doing a tool change and you are taking one tool off then mounting the other tool on just make sure theres no burrs and the next tool is but it up against the collet holder. the tollerance is pretty precise I would say plus minus .001 to .002 .
the reason I decided to go with the drill stops was because it was the cheapest way and fastess way to do a tool change and also all the drills would be set to the exact height
where I dont have to do a tool hieght offset every time I would run a program.
hope that helped.

hey ray
dont know what you mean by(measured the repeatability) but the way I do my part is basically I use one tool  to set my X,Y, AND Z  and that tool sets all my other tools
thats because I set them all up to the same Z as my first tool setter, (first tool) and basically when I run my program and I use multiple tools it works very acurate , but I must say I never move or losen the drills stops they are set pemanatly. even though I can readjust them if I had to.

I dont know if this might be of any help but what I do so set my tools is I just use one tool as my tool setter that tool will always touch the work piece and of that tool I set  my other tools I just add some drill stops that way when my program says tool change all I do is tell it to go to a certain height take that tool of then just put the next tool in and press start and it works fine.

hey ED
Is there really any money in the protype work  I would think there would be more in the production.

I have to say this has been a good topic
I must say once you have reached a certain level of knowledge how do you know its time to go work for yourself.
and also I say to myself if my boss made it (without the internet and many sites like this when you ask for help people are always helping with thing you dont even know how to do) I would think its alot easier to work for yourself  than it was before.
I have a question how do you guys see the machining and fabrication indrusty going is there still hope for a joung guy like me to go out there and start a shop.

so let me get this straight
on my g- code that I have posted I would just leave H and D at 0
and since I am using cutter comp all that I have to input the tool diameter for each tool, on my tool table offset.
is that the way it works
or do I input (H1 for tool 1) (H2 for tool 2) ect.
my point being is how do I make it  smaller if the part being cut is to big (.010)

hello and thanks for the replys
so if D=the tool number
and if H=tool lenght offset
what should I input on my code I have posted
or do I go to my table offset and input something in there
I am still unsure  on how they work if you could please explain a little more
on how to use them I would appreciated. sorry but this is kind of new to me.
thanks again

G-Code, CAD, and CAM discussions / can someone tell what the letter H and D stand for

I have been running my programs on mach but I dont know what the letter (H) stands for it appears after every tool change and the only thing that appears is H0
do I have to input some in there. and also there is the letter(D) it always appears after the g41 and g43 but it also say D0.
I am using cutter comp. when I do my toolpath. I use mastercam to generate my g-code.
can some let me know how to use those 2 letters.
here is one of my programs.
