or the tounge piercing that when they talk it sounds like they have a speech impediment
--------------------------------------------------------------------------------
Ever notice when they have their tounges pierced,they always have to let everyone know by hanging their tounges out of their mouths?
Why is this?
now now guys,
im probly one of the youngest ones here and i am willing to bet most of you, at one time, had long hair, or a pierced ear, even a tatoo, wore bell-bottoms, listen to that rock music, and you probly did it to be unique. with the population growing as it is its harder and harder for these kids to become unique.
by the way i have had my tongue pierced for 2 years and not many people even notice, most of the people that i work with dont even know yet, mainly because i dont talk funny with it or show it off, i did it for me:D

We balance everything running over 5000 rpms, especially boring bars, less wear on tools, better surface finishes, and round bored holes. we weren't even thinking about the spindle...lol
just the parts.

One other thing with G10's. We probe alot of parts every time befor the start of the program. The probe set the work offset. But the G10 line will reset it.
Jim
When we probe parts we use a g10 line to give the basic offset. Then probe the part, the probe will only update the info we want if there ar any shifts after the probe gets done we make them before it starts cutting, using the custom macros fixture offset callouts.
pete
if you are on a fanuc you can try using just the callout for the B axis as in the macro number for the B axis
#5224=90(or whatever you want to shift it)
#5524 is the B axis callout for G54

thats just what i was going to say, but if you are using a fanuc control the g10 line looks like this
G10 L2 P1X0.0.Y0.0 Z0.0 (P1 Being G54 P2 -G55 and so on)
extended offsets use a L20 instead of the L2(
B axis shifts are your friend
pete
the first 3 do but the last 2 dont have the same path, how can i change that?
EDIT: i figured it out thanks

Im posting a lathe program with 5 operations and 2 tools, when i post it only one op comes out in the posted code, all 5 will post individually but when i select them all they only post one. I know its not the post prosessor because i tried it with every one i have.
thanks in advance
pete
I was just wondering how many years everyone had under their belts(mastercam or machining in general) i my self only have 5(2 of which were in school) years total, and less than a year of programming exp.
anyone else?

Nice arguement but such an absolute statement is misleading. As always the particular application needs to be looked at. At my facility we use the tool probe in the machine, it takes like 10 seconds max to measure a tool, which is only done once. In our toolchange macro, we check the value in the offset register. If it's equal to 99 then it touches off to establish the length of the tool. After the tool runs we then check for breakage. Sure this takes time but the time we spend saves us scrapped parts and crashes.
well you are correct in saying that the particular application needs to be looked at.
What i was trying to say is that basicly the presetter can greatly improve set-up time and save money, any time the spindle is not turning(unless measuring parts) it is not making money.
with a presetter you can measure tools wherever you want to also.
a probe can't easily measure a drill at full diameter, or a port tool at a given dia/angle. when a depth of a certain dia. is critical you cant count on every drill angle or port tool to be ground exactly to what its supposed to be. why wait until the part is cut to find out that you had the wrong anlgle on a tool?
we only use the probe in the machine as a broken tool sensor because that is all its good for.

Is there a way to export from the "off-line" presetter to the CAD station? So when it's posted, it can post the TLO data as well instead of having to type it into the machine, (error inducive in it's self, 'specially with fat fingers.. )
not exactly to the CAD station but,
yes there is, there is actually a "post-processor" in our presetter that sends the data for a particular job to the file folder where the part program is stored, and it gets loaded right into the machine with the part program.
we also run a check to make sure that the tool length is equal to a given dimension(plus or minus a certain tol.) before it cuts the part.
pete
CNC machines are built to cut material not measure tools, measuring tools in the machine costs money. with the money you save on set-ups with a tool presetter you can pay for it within a year, depending on how many set-ups you do. we have 2 now and i dont think i have ever touched off a tool before(except for when i was in school).
Say you saved 10 hours a week on set-up with machine rate of $50 an hour(this is a very low rate, i know) you would save $26,000 a year if the tools were preset offline. Also it is a good idea to load the offsets into the machine by program, not by operator(saves the chance of fat-fingering the tool offset values)
Just my 2 pennies
Thanks James
for some reason when we got our post this code all had ## in front of it. I cant think of any reason why, can you?
if mi1 > one & workofs <> prv_workofs,
[
sav_absinc = absinc
absinc = zero
pbld, n, sgabsinc, pwcs, pfxout, pfyout, pfzout, pfcout, e
pe_inc_calc
ps_inc_calc
absinc = sav_absinc

i guess that is what i was asking,i know what i need to do now but how to do it is another story. i have made a lot of post edits but ive never changed anything like this, so what i need to know is what are the variables for the wcs and previous wcs
