Edit Post to output correct thru spindle coolant codes.

[Justin Beebe at Folsom Tool]

I'm using thru the spindle coolant for the first time on our Haas UMC-750 machine. The M88 code turns the thru the spindle coolant on and the M89 code turns it off.  I am currently using X8 with a post I updated from X6. When I go to my coolant parameters page and select the drop down arrow for thru-tool the options are ignore, M08, and M09.  These are the same options that come up under the flood coolant drop down arrow. I also searched my post for M88 and M89 but nothing comes up.  I was hoping there was a way to make these codes available in the post and also have them show up on the drop down menu on the coolant parameters page.

 

Any help is appreciated.

You'll have to go into your post and search for the "X Style Coolant" block, and in there define the coolant codes your specific machine uses. For example, this is how I modified mine for an Okuma MA400:

 

# Coolant output code selection for X style coolant
# Note: To enable X style coolant, click on the General Machine Parameters icon
#   in the Machine Definition Manager, Coolant tab, disable first check box
#   Output of X style coolant commands in this post is controlled by pcan, pcan1, & pcan2
scool50 : "/M8"                 #Coolant 1 on value
scool51 : "M9"                  #Coolant 1 off value
scool52 : "/M50"               #Coolant 2 on value
scool53 : "M9"                  #Coolant 2 off value
scool54 : "/M50"               #Coolant 3 on value
scool55 : "M9"                  #Coolant 3 off value
scool56 : "/M339"             #Coolant 4 on value
scool57 : "M9"                  #Coolant 4 off value

 

After you do that, you can go into your coolant parameter page and define the label for each one, i.e. I have coolant 4 as "THROUGH SPINDLE AIR BLOW" and my options are /M339 for on and M9 for off.

cathedral,

 

Thanks for the info.  I'm still messing with the settings.  So far I got the M88 to work but it still posts a M09 to turn it off.  I'll mess with it some more after I finish my part.

Cathedral,

 

I have correct coolant codes working now.  The reason I was getting an M09 instead of M89 is because I had the box checked that said "first coolant off command shuts off all coolant options."  Now the problem I am having is the post is turning on the coolant in the wrong place.  Haas recommends the  thru spindle coolant be turned on before the spindle starts but it has to be after the tool change.  Here's an example of the code.

You're going to have to move some things around in your post to get the correct output location. Are you experienced/ comfortable with editing your post? It should be an easy fix, but unfortunately I only have experience with Okuma and Fanuc posts--the postblocks in my posts are probably different from yours. Are you using a default post that came with mastercam or one that you bought from a third party?

The post was purchased from In House.  I can send it to our reseller and they will fix it but I'm trying to learn how to do it myself.  I have low level post modifying skills.

 

Thanks for your help.

You need to start the M88 with the FIRST clearance plane move AFTER a tool Change. It will stop the spindle to turn it on, the restart the spindle and then continue.

That's how my VM-3 is setup.

Thanks machine guy I will look into that tomorrow.
