For the Citizen experts. Is there a way to incorporate the cutoff process and start position process directly into the program rather than having to do it manually?
What macros does it read for the cutoff, and for the move to start position? These questions are for a L20 M7 and M8
Thanks in advance
Brett

Yes there is a way.

Load the attached file into the machine and call it as a SUB program at the beginning of $1. MAKE $2 WAIT UNTIL IT IS COMPLETED.

$1 ................................. $2
M98P322
!2L322 ........................ !1L322


This is for the L7-20. There is NO M7 or M8 machine.

You need to call the cutoff tool into position and position the stock FIRST!!

[chet470]

Thanks for the reply. I new to citizens and was referring to the model # on the manuals, it says 5m7 or 5m8 which is where i got the m7 m8 from. Anyway thanks for the information. And what excatly is program 322?
If i have to position the cutoff tool first would something like this work

$1................................................ .................$2
IF[#5041LT0]GOTO500......................................!L322
T0100
G0X[#814+.05]
M98P322
N500
!L322

My goal in this scenario is to put a safety check in place in case guys forget to move to start position which seems to happen regulary.

[chet470]

Didnt see the attached file! Thank you!!

This program will got into alarm if the cutoff tool is not in position. The screen will read "Call Cutoff".
If you do a tool call as you show it will add cycle time on EVERY cycle.

FYI,
5m7 = L5-20 (5th Generation L20), Type VII

5m8 = L5-20 (5th Generation L20), Type VIII (Added capibility, Gangblock)

See the attached file for a line-by-line explanation of what will be done by that program.

Just to expand on your breakdown, M is for Mits, F is for Fanuc

I am trying to use this on my L6-32 but i am having trouble with the G53 -#818. It wants to go to minus what is in my mc data from machine zero. It is not going to the start position.

[cogsman1]

For that machine change that one line to be

G53Z#872-#818

The system settings are different between some models.

[jessebpm]

thank you. I am trying to learn how all this stuff works. Kinda got thrown to the wolves with the swiss machines. Learning as i go though..

[jessebpm]

I am still having problems with this on the L6-32. I changed the g53 line to #872-#818. The first time I ran the program it worked just like it should, went right to start position after cutoff. Now every time after that It wants to go forward toward the guide bushing and alarms out.

[ProProcess]

what alarm?

[jessebpm]

Z axis over travel. Traveling toward the GB this time.

[ProProcess]

Well, are you in OT?
Can you move Z1 in manual?
When you run your code, what is the MC COORd for Z1?

[cogsman1]

What does the "distance to go" show? What axis' still have movement to go?

[jessebpm]

just Z1 axis list a distance to go. It is something like 10 inches positive. If i go back to G53 z-#818 it also alarms but a negative distance to go.

[cogsman1]

There are only two options and one of them is correct. Be sure you are entering them in correctly.

G53Z-#818 (Z - #818 )

G53Z#872-#818

[jessebpm]

Ok i am certain i have entered everything in correctly. Like i said though if you do this first thing when the machine is powered up it works. if i manually do a start position or if i run this start position prog twice, the second time it does not work.

Here is what i just took out of the machine

Try this change

(START POSITION)
IF[#5022EQ[#872-#818]]GOTO991

Let me know the "Machine position for Z1 when you do a normal "Start position" and the "Machining length" from your MC DATA IF this does not work.
