Leadwell MCV-550 toolchange macro

[gbowne1]

Would someone here a post a copy of the toolchange macro from a Leadwell MCV-550 with a FANUC control.

Preferably one that has a 10 or 11 control or a 0.

The one I have is not working very well.

In what way is it not working well? Normally the issue is when you need a copy of a Tool Change Macro is when you don't have it at all. If you have a Macro program that once worked, problems more likely occur through proximity switches not being made during the tool change sequence. With the Umbrella type tool changer on the Leadwell machines, there is a bit of interaction between the Macro program and the PLC via the interface System Variables.

Unless you're missing the Macro program all together, or you know for sure that the one you have is corrupt in some way, another Macro program may not help.

If you post the one that you have, I, or someone will be able to tell you if its OK, but it will definitely be helpful for you to describe the problem.

Bill

I'd check for a stuck 'mag forward' limit switch, or chips hitting it early- its caused ours to drop tools before. I found out the hard way on newer (MCV-760 0M-C) leadwells that theres a thing in the ladder that disables the cycle stop if ATC dont fnish the last step...I was setting one up, atc was balky, I changed the tool by hand(atc cycle hadnt finished, just homed/reset), I dumb thumbed my offset and it tookoff (only 50% rapid- still quick)towards the table- hit stop/did i hit the wrong button-pounded stop again/paniced and hit estop just as a $500 Hertel drill coasted into the table... thinking it had a bad op panel, dug into it and found they had decided ATC was more important than stop??? at least it didnt disable estop.

anyway, the only other common problems were misalignment(at atc height, reset/shutoff air/slide mag left-right, be sure it engages smooth) and tools stuck in the taper- if the 'unclamped' switch hits before knockout dimension(usually does as its only like .02") the slide will try to pull away, often taking thge pocket/spring/part of the umbrella casting with it. best fix there is get the taper reground, replace the bellevilles and dont run any old tools- we have a bad habit of not checking drawbar pull till the taper/tools are already suffering 'fretting corrosion' from vibration/moving, then they get sticky...

I dont have to old macro- we pitched the umbrellas years ago and went to table mounted(we only use 2-4 tools) fixed pots... a little slower/loses some work envelope, but easy to clean/nothing to break... you will probably need the macro for your 6 anyways- addressing/logic probably evolved for better or worse on newer ones...

Mine is a MCV-550S.. there's a couple different models.

When I bought the leadwell, someone had cleared out the control, including all the 9000 programs.

The actual 0M control on there replaced the 10/11 that was on the original machine.

I've tried variations on this one.

As for tooling.. I only use the best CAT40 I can get. Now I use ERI America tools that are balanced G2.5 and I found that the more expensive tools clamp better. I also only use the best quality knobs I can get. I do have a replacement spindle that came from a low time machine. The belleville washers are new. Leadwell sent me a bunch and so is the gripper(s).

M19 is right, it does orient but it seeks a little bit excessive. The encoder is new. Goes to the 2nd, and moves the carousel to the right pot index just as it should to whatever number I called. Just the S arm does not complete the change. I don't get any op. messages or specific alarms. Manual jog (CW & CCW) via the two button panel works fine.

I'm so used to keeping my old Fadal 4020 carousel clean.. that I routinely clean the whole ATC, spindle, etc. on thel Leadwell. Fadal's will toss tools at ya if you aren't meticulous. I even take one of those spindle wipe tools and clean it that way.

I was wondering maybe this macro is stored on the macro cassette.

Yeah tc I do have to work on the 6M toolchange macro too.

I'm supposed to end up with a MCV-610 here soon too. This is in part due to a payment from a customer. Instead of paying me, they are giving me a old machine and sending a check for the rest of the amount due.. Gee I'm (almost) running out of space!..

Unless most, if not all, the work is done in the PLC, there is interaction between the Macro program and the PLC. For example, if a lot of the work is done by the Macro program, then it needs to be held up until proximity switches for Carousal Advance etc are made. This interaction can be achieved via Interface System Variables. I have a number of Tool Change Macro programs written to use these System Variables, but for it to be viable, you would need to study the PLC program to determine if the Interface signals are used, and if so, which ones.

Your program above is for a machine where the PLC does ALL of the work. The Tool Change routine in the PLC would be initiated by the M6 in the Macro program. O9001 would be called by M6 in the main program, and then M6 inside O9001 is treated as a normal M code.
