Mori Seiki Lathe post issue

[MSL]

Hi,

I'm trying to take the M45 out from my turning operation. This happens right after a milling operation on our Mori Seiki lathe. I started my post with Generic Fanuc 4x MT Lathe post.

M45= C axis active

Hi Ara,

 

It looks like you added the "M45" into your post. Did you use the existing "C Axis mode" variables?

# --------------------------------------------------------------------------
# C axis mode
sm23    : "M23"      #C axis enable
sm24    : "M24"      #C axis disable

If yes, then the 'sm23' and 'sm24' variables are used to enable/disable C-Axis mode.

 

These codes are output using conditional logic from these two post blocks:

 

pcaxis_off_l

pcaxis_on_m

 

The main variable that is tested (and you can use as you see fit), is 'posttype$'. This variable is "2" when Lathe is active, and "not 2", when Milling. The 'posttype$' variable is "updated" (!posttype$) at the end of the 'ptoolend$' post block. That means inside of any of the "Tool Change or Null Tool Change" post blocks, you can test the previous (prv_) value of the variable, to see what the "last" mode you were in, and output the C-Axis enable/disable, based on the current/last values of 'posttype$'.

 

A simple line of logic for testing Lathe mode, when previous was Milling:

if posttype$ = two & prv_posttype$ <> two, *sm24 #Deactivate Mill Mode, if prv_ was active

That line above could be added to the 'ltlchg$' and 'ltlchg0$' post blocks, or you could modify 'pcaxis_off_l', and leave the existing structure in place.

 

 

The same for testing Mill mode, when previous was Lathe:

if posttype$ <> two & prv_posttype$ = two, *sm24 #Activate Mill Mode, if lathe prv_ was active

That line above could be added to the 'mtlchg$' and 'mtlchg0$' post blocks, or you could modify 'pcaxis_on_m', and leave the existing structure in place.

 

 

Hope that helps,

[MSL]

Hi Colin,

Correction, the post is a Mori post from post installation folder and yes it's using C axis  mode. I couldn't fix it today but I will spend more time tomorrow.

Thank you for your help.
