Fanuc Wire W1 Taper Cutting
Hi all.
Looking for some help machining an internal tapered gear using a Fanuc W1 EDM.
I have managed to create a program using AutoCAD just tracking the points of the gear, using G90 (absolute) coding and then tracking the difference between the top and bottom forms using V and U.
A sample of that: Y.4635 X.0196 V.146 U.0062
4 lines to describe the gear tooth on a sub-program and then use an M98 and Q figure to duplicate. It worked, the graph shows both the top and bottom forms properly and the length.
Then I come to setup the taper cutting on the machine. I have never taper cut before so am learning from the ground up and using the manual. But the manual is a translation from the Japanese so it doesn't exactly work grammatically.
I need some information on how to setup the taper screen (Set/Taper) where you change the taper cutting data. (I tried to change to simple taper cutting but it only came up with a 40 alarm)
What cutting mode do I use for instance? Is it just 1 for taper cutting or 10 for direct instruction of the UV axis?
Do I need to use G51/2 if I'm using an NC style of program?
Any other things I might need to know?
I can post some images if needed or if anything isn't clear.
Any information you can spare or suggest would be really appreciated.
Thanks
Chris.
