Here's a interesting measurement Macro from my Lathe.

I guess issued by G65 P9018 X xa;

O9018
#1=#4001
G00 X[24-10.0];
G31 X[#24+5.0];
IF[ABS[#5061-#5081-#24]LT5.0]GOTO 9018;
#3000=80(PS);
N9018#4=BIN[BCD[#4120]AND255];
G10P#4X[#5061-#24];
G #1 M99;

I thinking it could be made a little bit better becuase what it seems to do is some tolerance checking and X axes setting of the automatic tool offset.

aren't the macro's suplyed by tha probe manufacturer??

[gbowne1]

Yeah they are usually.

There's a few of them in my lathe. They all seem to do slightly different things. I'm used to the measurement in the mill.

My mill probe is a CAT40 renishaw MP3.

This macro uses the G31, G10P plus a IF statement and variables. My others don't.

That doesn't match the format I've seen for Renishaw Lathe Macro 9018. Normally 9018 is a Z Axis measurement, but the format looks different.

[gbowne1]

Yeah, that's why I mentioned it.

It's not a Renishaw macro.

It just made me wonder. Theres a similar macro in the FANUC manual.

[duivenhok]

can't help you on this other than that i could suply the renishaw macro's that are in my lathe

[fordav11]

I'd be interested to see a lathe Z measurement macro if you have one?

[duivenhok]

gonne look into it.
if i have em at home i'll post in a moment. if not gonne get them from work tomorrow.

[duivenhok]

as mentioned Z measurement macro including used submacro's.

I 'm bit familliar with parametric programming but translation this to what it actually does is gonne take to much time for me.
Might be easyer for you.

[fordav11]

ok thanks.
do you have any info on what the various user-input local variables are used for? For example #3, #4, #9, #17, #21, #26 etc and several on the G65 lines such as G65 P9030 D[#26] V[#22] E[#3*#7] H[#11] M[#13]

It appears #26 is the target Z point but even if the actual numbers are known a text explanation of the variable usage is needed otherwise it doesn't make much sense :-)

Or maybe you have another program that sets all those numbers? I assume there is another program because local variables are cleared on power-off/reset so it would be dangerous to run that macro program without something that re-sets the local variables first.

[gbowne1]

Me too. I would like to learn this type of macro / variables usage. I've only recently started using the Renishaw MP3.

There's supposed to be some sort of measures on my Mori SL lathe. No saved programs for this.

I still have yet to implement measurement on the 10TF.

[fordav11]

on older Mori SL lathes there's no probing but there can be a setting arm. no macros are used though it's purely for setting tools.

Read all about it http://www.promoil.com/tools/renishaw/21.pdf.

Myself, I only use diametrical meassuring once in a while on a lathe with loader system. but although is seems great its use is limmited.
When using a inserts drill the disc that shoots out at the back of the product might break the probetip.
Also you must be sure that u dont produce long "stringy" chips (not even once in a while) because these might twist and grab the probetip and break it.
For cast iron matrials (with I almost never have) and other short chip matrial its a great tool letting you produce the whole loader table without making scrap parts once in a while.

[gbowne1]

I've only just started using the Mori SL3H in the last 6 months o I haven't gotten very deep into it.

Well, the 0T / OT which has a A02B-0091 system also has measure too with the macros.

I just touch off and use the calculated X and Z for finished parts.

The 10TF I normally work on has macros similar to the 15T I investigated beforehand the build.
I use pretty efficient chipbreakers so chiphandling is pretty neat. We don't use insert drills except in milling.
