'Fanuc 15T offset parameters'

Steve (2) from Wisconsin - Tue Apr 29 13:41:33 2008

I am programming a Fanuc 15T control on a VTL. There is no preset relation between a T-code and a tool offset. This is all designated ex. T1936 Tool 19 offset 36. I cannot find the parameter that will give me the offset of the instated tool. I am writing a custom macro to establish the tool radius and calculate theoretical points. Parameter #4120 gives me the tool post and offset associated to current tool but when programming for example #30=#[#4120+2900.] alarm variable out of range arises. Please advise.

Please advise. I am having no luck with the machine tool builder.

I did not want to have to write a program to loop through every tool change but this is the only way I see capturing the tool radius when needed.

T1632--Tool 16 offset 32

#1033=16.--Set by macro in tool change

#4120=1632.--Set by macro in tool change

#1=#1033*100--(=1600.)

#2=#4120-#1--(=32)got the tool offset number

#30=#[#2+2900.]--(this will grab the tool radius from offset page for offset 32)

Thanks for all your help and responding.
