broken tool detection


Recommended Posts

All,

 

I'm working with MPMaster to try and get broken tool detection for our Makino PS95. I'm using Misc Integers to do so. I have it down, but the only part that's hanging me up is outputting the tool diameter. The disc for the tool setter on the Renishaw is only 10 mm or so. SO if the tool is bigger than that, it has to be offset half the diameter. In the pretract section of the post I have this:

 

pbld, n$, sgabsinc, sgcode, [if gcode$ = 1, sgfeed], *sg28, "Z0.", [if gcode$ = 1, feed], scoolant, e$

if sav_mi1 = 1,

[

if tool_typ$ <> 3,

n$, "G65 P9858", prv_t$, (if tldia$ > .375, *tldia$) "H.005", e$

else,

n$, "G65 P9858", prv_t$, "H.005", e$

]

# if lock_codes = one & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$

# pbld, n$, *sg28, "X0.", "Y0.", protretinc, e$

# if lock_codes = one & rot_on_x & cuttype = 0, pbld, n$, *slock, slockcomm, e$

 

But all I can get out of that is the NEXT ops tldia$ value. For example, If I have a 1.25" shell mill followed by a 1/2" endmill, at the end of the shell mill, I can get the right macro call, but with the next ops tldia$:

 

 

(1.25 SHEAR HOG TOOL - 12 DIA. OFF. - 12 LEN. - 12 DIA. - 1.25)

I've tried using the prv_tldia$, but it's not happening. What am I missing?

It looks like you are working at the end of the path

 

I would suggest in the tool change section save the tool dia to it's own created variable

 

sav_tldia = tldia$

 

The use the created variable
