Hello.
I have posted about this already on here and I got no replies at all. Am I asking wrong, or is this something no else has run into?
I will try again and hopefully someone with more experience than myself will be able to point me in the right direction.
I am having a problem in v24. I generate a drawing for a hole and then select ‘contour ramping’ in 2 axis milling to interpolate the hole. I am using a Fanuc 18 post processor that I downloaded from Bobcad. When I post the program, it gives me all of my circular moves to make the hole, but no ‘z’ move to move the tool down into the part. So, I wind up with a bunch of lines of code that are I’s and J’s only. When I run it on my machine it moves to the top of the part and proceeds to do the number of revolutions that are programmed without moving down any further.
If I draw a rectangle and do the same thing, the code posts perfectly. I get an x, y and z move on each line.
I get the same result (no z move) when I try to do thread milling.
What I am (obviously) trying to accomplish is helical interpolation to produce holes with a cutter. Am I trying to use the wrong cycle? Do I have a parameter set wrong?
Any help/suggestions would be greatly appreciated.
Thanks
Scott
