Oversized Tool on Toyoda FA550II 15M

[Garban]

I posted this in the Toyoda forum last week and got 0 replies. Maybe somebodt here can help me.

I need to use a 14" diameter tool on a new project in my toyoda. Obviously I can't put this tool in my tool changer. What I would like to do is build a "parking spot" on my tomb stone to place this tool while other tools are being run then load this tool from the parking spot and return it to the parking spot when finished. I have a 61 pocket tool changer. I would like to be able to do the following:
1. Create/edit a macro that if the T code “#20” = 99 then tool 0 is loaded into the ready position but #1033 = 009900XX.
2. Edit 09020 “M6 macro” that if #1033 = 009900XX it loads tool 0 into the spindle then loads the 14” cutter from the parking spot.
3. Edit 09020 “M6 macro” that if #1033 = 00XX0099 it parks the 14” cutter in the parking spot then loads the next tool "XX".
I’ve seen this sort of thing done before but am unsure where to start. There is no macro for the T code. If I do a T99 in MDI I get a AL40 T-Code Alarm. Am I crazy?

Thanks in advance

Crazy? I am not a psychological medical professional. Seems like you might be going about it the hard way unless someone can just give you the answer. If your machine can use M-codes to execute tool clamp, unclamp, and spindle orient, I would push for that.

Can be done in sub-calls:

(Tool pick up)
T20 M06 (Empty tool pocket)
G00 Xxx.xxx Yxx.xxx (Rapid to align with oversized tool)
G00 Zxx.xxx (Rapid to just above the tool)
M19 (Orient spindle)
Mxxx (M-code for tool unclamp)
G01 Zxx.xxx Fxx.x (Lower spindle onto tool)
Mxxx (M-code for tool clamp)
G04 Xxx.xxx (Delay)
G00 G28 G91 Z0. (Rapid to clear - ready to machine)

(Tool drop off)
G00 Xxx.xxx Yxx.xxx (Rapid to align with oversized tool drop off location)
G00 Zxx.xxx (Rapid to just above tool drop off location)
M19 (Orient spindle)
G01 Zxx.xxx Fxx.x (Lower spindle to tool drop off location)
Mxxx (M-code for tool unclamp)
G04 Xxx.xxx (Delay)
G01 Zxx.xxx Fxx.x (Raise spindle off of oversize tool)
Mxxx (M-code for tool clamp)
G00 G28 G91 Z0. (Rapid to clear - ready for next command)

Thanks Taxman,
I know what you're saying will work. But the possible hazard of some one manually typing T1M6 in MDI while the oversized tool in the spindle still exists. The machine will still TRY to put the oversized tool in pocket 20... messy. That's why I want the machine to recognize that if T99 is in the ready position or in the spindle the next M6 command must be handled differently.
The Toyoda manual say's it's possible to link a T code to a macro but doesn't say anything about how. This would be the safest way to handle this.

Thanks again. I will use your method if I can't find a safer solution in the next few weeks when the fixturing gets finished.

When I have had oversize tools in I made a cover over the toolchange button. As long as you can remind some one, somehow, not to do something stupid, it should be OK.
If they can use an MDI function, they need to think before executing it, and possibly at reduced feedrate.
You drive down the street and choose not to hit the trees.
And if you pay monkeys you get peanuts.
