How to call the same tool before next cycle.

[Anonymous]

Hi, 

I'm boring out a part on a Fanuc based lathe. I'm using the same boring bar for both the roughing and finishing, tool T0303.

In the Gcode posted from Fusion 360, T0303 is called to do the roughing cycle, but not called again before the finishing cycle, which is straight after the roughing.

I want the tool to be called up again, even though its just been used, so that i can adjust offsets and re run that cycle without running the rough cycle. 

Is there a way to force tool calls in post or in tool settings? I could edit the Gcode, but for large programs with lots of tools that gets a bit tiresome.

Thanks

Ben

You will have to look into "Safe start all operations" I know Haas mill has it but dont know if you can copy something similar from lathe or if your post has it but dont know to search for it under that name. What post are you using?

I'm using the built in "FANUC Turning / fanuc turning" post. 

How do i set it to safe start all tools?

It will need to be added to your post.

You can stick a manual NC in the gcode use optional stop in between the tool paths to stop the machine the M1 will be at the end of the first toolpath so you can do your check.

He should be able to insert a Manual NC - Force Tool Change in between operations.

So with this code, I need a T0100 between lines N31 and N32. That would allow me to run the whole program, then if the size is not correct, adjust offsets and re run (FACE1 2) lines N32 - N48. 

The reason I want to do it this way is because the machine is worn, and the operators are usually very inexperienced.

N31 is the manual NC added as Neil said you can forces a tool change as well, all the options you have are below.
