RE: [CAD_CAM_EDM_DRO] inexpensive 4 axis CNC software (yeah, right!)

Re Rotary Axis

I did'nt comment earlier because I thought the enquiry
was for CNC control software for the 4rth axis and not CAD/CAM.

I can confirm that Dolphin has rotary table support in which the
X or Y axis can be replaced with a Rotary axis for Indexing and
Interpolation (not 4 Axes simultaneous).

If the requirement is to Contour, Pocket, Drill, Engrave
(including True Type fonts) on the outside of a bar then Dolphin
has these facilities.

If any further details are required contact me direct.

Ha Ha Ha Ha Haw!!
Yup, it's a long shot all right.
Last time I checked out Mastercam mill level 3 (not quite up to 4 axis yet
without a nasty custom post processor) we were talking about $15,000.00 USD.
Most 4th axis work is faked on the rotary axis anyway, (one axis is swiped,
and used to drive the rotary table) and the rotary axis typically moves in
very simple ways, and not in conjunction with more than one other axis.
(okay, I ignored helical tapers)
You should be able to fake it with any normal CAM system by hand coding the
rotary moves, and doing the appropriate axis swap.
If you need full four axis simultaneous interpolation, for "surfacing on the
round" like say machining a human head like shape, you are in for either a
programming nightmare from hell, or a post processing nightmare from hell.

>ok, so it's a long shot. but does anyone know of an inexpensive 4 axis CNC

software that will run a closed loop CNC mill on windows NT or 2000?
