Need help on Part Counter

[fahed]

I am using a CNC Lathe with a bar feeder attachment and the cycle time for a part is 1minute 33 seconds, My problem is its a mass production and when I place M30 at the end of the program I have to press "CYCLE START" after a component falls off, I loose some time there since time is very important,

If I replace M30 with M99, the program runs over and over again after parting, but the problem here is when I press the "POS" button on the controller, Part Count = 0, Cycle time = How much time the machine has run after I hit the "CYCLE START",

I need the program to run without hitting the cycle start button over and over again and see how many parts have fallen and also the cycle time for each part not the whole session.

I doubt that you cannot get individual cycle time, because cycle time counter is restarted only when u command M30 & as in your case u command M99...So can't get the individual cycle time.

For the Part Count, follow the instructions -



Before pressing cycle start, turn the Part Counter to 0


In your program command,


#xxxx = #xxxx+1;
M99;

(Where xxxx is the Parameter number which traces the Part Count...)

(Consult your Machine Dealer to know about the parameter which stores PART COUNT).

I use a Galaxy Midas 0 machine, In the Parameters I could see in Help of the mahcine its shows 6700~, But when I used 6700, I get a error, illegal parameter used.

U have to ask to machine dealer...Or do post a new thread asking about parameter number which traces part count in forum of


"Paramteric programming".


But i suggest to ask to machine dealer...

According to my knowledge, the program mentioned is right...

I use macro variables as a part counter. How you would use it depends upon what control you are using. Mine is a Fanuc 10TF. At the end of the program, just before the M99, I have a "#549=#549+1. I can adjust that number while in MDI mode if necessary, like when first setting up a job,I can adjust to zero, or subtract bad cycles. Do you know which control you have, and whether you have Macro B installed?

[fahed]

I use a "FANUC 0i mate-TC", Could you help me in detail how do you set that parameter in MDI mode. I have never used the MDI mode.

[Ashish B]

Simply Program the following code in MDI.


#xxxx = 0,

(where xxxx is Parameter which traces the Part count

setup so that your main program is a sub routine then loop it to the number of parts/bar

I called up the dealer, He gave me this code "M90" before m99, & this worked, Thanks all for your help.

Hey what's M90 ??

[fahed]

My Machine dealer says its a code to add 1 to the part counter, so if I put M90 10 times in my program, I would a part count of 10, Can you tell me what is Macro B and what is the advantage of it.

Thanks in Advance.

M90 is a machine-builder added in feature not available on most makes of machines unless they too want to build in that M code. They would add it to the PLC side of the control. Don't expect to be able to use it on other makes of tools.

Macro B is a programming tool that allows you to have changeable parameters within your program. If you have a family of parts, for example, with different bore sizes, one program could be written that would suffice for all, with a simple change in the macro variable table that would modify what the program would do. There are conditional branch commands, calculating functions, I/O testing (if you know the address for that I/O). Counting is one of the simpler things you can do with Macro B. You could also set up the macro to stop the machine (M30) when a certain number of parts is reached. Powerful tool.
