Tool breakage detection okuma p300m

[cabrone]

Need a macro for okuma osp p300m that will check the tool to the tool probe after the tool is used and if length is short (broken tool) alarms the machine

[nickc]

renishaw software on our machine uses m204,this should be installed by your okuma guy when he set the probe up

[Brad Lisle]

I highly recommend using the Renishaw macros, however if you don't have the Renishaw macros/software installed here is the Okuma macros for tool setting/breakage. You can change the O# to what ever you like and assign it to whatever library M-code you like, I however typically set them to M201 for tool setting and M202 for tool breakage. Be sure to read the comments as there are a couple of parameters I recommend setting. You will also need to make sure you calibrate the tool setter using the Okuma macros, see the attached sheet for procedure. Let me know if you need help assigning and registering the library files. 

Save the following into a .LIB file:

 These macros use common variables,  VC30=X-axis shift, VC31=Y-axis shift and VC32=spindle orientation. Note that when the cycle is complete the macro will reset the common variables back to zero. With the variables at zero it will act as if tool is on center. In program tool breakage would look something like this:

VC30=.25 (X-AXIS SHIFT, THIS EXAMPLE IS FOR 1/2" ENDMILL)
VC31=0 (Y-AXIS SHIFT, THIS EXAMPLE WE ARE SHIFTING X-AXIS NOT Y-AXIS)
VC32=0 (SPINDLE ORIENTATION, IF YOU TAKE CARE WHEN LOADING TOOLS TO)
$ (ALIGN A FLUTE IN LINE WITH SPINDLE ORIENTATION YOU SHOULD NOT NEED)
$ (TO USE THIS OFTEN. TYPICALLY ONLY NEEDED FOR ARBOR HOLDERS WHEN)
$ (YOU CAN'T CONTROL THE TOOL ORIENTATION)
M202 (TOOL BREAKAGE CHECK)
