Problem- using extra tools.

[TAdams_R&D]

I am using Fanuc controls and require the use of 30 tools. The machine only has 24 positions. How can i add the extra tools to use manually in my program?

Adding a manual tool change would be easy, just position the tool within easy reach of the opperator and program a

M00(Load Tool #25)

The problem is what to do about tool offsets.
You could choose your tools for manual change carefully.
Like tools that don't need to use diameter compensation such as Drills and roughing endmills.
Also make sure the tool length offsets of the choosen tools is less critical.
You need to offset the tool length by hardcoding the actual length within the Nc-Program.
Or use the actual length from within your Cam Program.
Instruct the Opperators to use exact tool length callout to make this repeatable to replace worn or broken tools.
A little more work but doable.
Good Luck

Check your tool offset page, I'll bet it has more than 24 tool offsets available.

I do a similar thing on a lathe when I need to use a longer than usual tool but leaving it in the machine would cause it to hit the chuck or steady. I leave it out, run the program to that point then M00. Bolt in the tool including it's holder with pre-set offset, use it then M00. Remove it and continue. A comment in the program with the M00 ensures the operator knows what to do.
works fine as long as the tool is not cutting critical/toleranced sizes.
