yes exactly

thing is we don't have a CAM system at the shop yet and haven't
needed one for most of the work we do ,this was the first job in
about 4 years that we couldn't quickly program by hand at the machine
so we decided to farm out the programing at $80/hr rather than spend
big bucks for software that would just collect dust most of the time

the programers (all three of them) just couldnt figure out how to get
their high end CAM system to handle the Y-axis along with the A-axis
and went with a 3 axis centerline toolpath (X,Z,A)
rather than a true 4 axis path (X,Y,Z,A) that would have done what we
wanted
probably more of a wetware problem than a software one
- much harder to debug ;-)
