Haas machine soft limits / work zone

[Chris Rizzo]

I've got a trunnion the the right side of the table, and use the left for vice work. Any ideas on a way to limit machine travel out of the trunnion zone? If the spindle is down and someone hit's X home, the trunnion get's wiped out.

On a HAAS not that I am aware of. Other machines that have safety zone abilities built into to them yes, but HAAS is not one of those machines that I am aware of that can do it. Make a Policy the damage is coming out of that person paycheck. If at the school good luck.

Unfortunately the school of hard knocks taught me to always zero z 1st unless dealing with a wheel cutter stopped in the slot but that another story.

 

good luck

Last resort I'll go gorilla-style and build a big weldement to house the trunnion. I'd rather wipe out a (disposable) haas spindle than a trunnion. Although it will undoubtedly kick the z axis off too.

Chris,

Build a geo file of the exact table and a 3d box the shows the position and size of the trunnion.

Use that as a base line for all the work on the other side of the table.

watch out for the coolant noozles ( and air if equipped) on the head of the machine.

 

That now becomes you violation zone.

This wont help when the operator moves the machine in manual mode.

Yea, thats true. On a Hass lathe you can.

Haas should add a saftey zone in the mill software. I have to remove the air nozzle when I put on the forth axis on the VM-3.

There are only 2 of us that run the machine. So Im safe, so far.

anyone who can manually crash a CNC might want to consider training with one of those sticks with the fuzzy thing on the end.

 

 

you might also consider installing a secondary home button on the haas. it will move machine to an easily designated position AFTER auto retracting z.

 

if one really wanted to go crazy you may be able to floppy-load parameters that tell the machine it has half the travel it actually does.
