OT - Mazak Tool Break Detect

[John Morris]

Anybody had any luck getting the tool break detect to work using G-code programs? It works in mazatrol and simply calling the M-code does not work, I can postion the tool and open the probe, but still not activity on calling the M-code. Mazak says it will not do it, but I'm thinking why not?

Could you do a sub call to the mazatrol program?

Work fine on our machines

We have made our own tool break detect program in ISO for a MAZAK PFH-5800... It's working very fine, but I honestly don't know if it will work on a 1992 model.. Looks like this:

I can see this is going to be tricky.

 

This machine does not have the Laser for tool break check, all I have is the probe that comes out and basically has 2 proximity switches, one decelaration sensor and the one that actually measures the tool position.

 

Second, I cannot call a mazatrol program from an EIA. (I can call a EIA from mazatrol only).

 

Finally, this machine does not have the macro option.

 

Although the program from Guffie has got me thinking about the skip function thing, maybe I can make that work somehow. I can get the machine in position, I can open the probe with an M-code, I can probably figure the distance to travel to the first proximity switch, but I need to figure way to check the activation of the switch. G31 as shown above my work, I'm not sure. Even if I don't get an alarm but the machine just stops trying to touch the probe it will prevent a crash.

 

Anybody have any insight on the G31 (G31.1-.3) option before I get too deep into the manuals?

[Guffie]

I must admit that I'm not that much expect on the G31 codes... I only use the program, and have got it from a EIA freak some years ago... But it's working perfectly on our Mazak machines...
