5 axis cnc Porsche head porting

Wow, a Haas that is running. You don't see that everyday.

Unfortunately, I have to agree. Both of my Haas machines have been very problematic.

haas vfs vf3 cincinatti horiz. cin. 5 axis, pays to be a machinist

i run a HAAS VF2,VF3,VF5 and VF9 nice video

Nice Machine, I run a new VF3 with the same 5 axis setup at work, pretty slick, can't wait to do some after hour's cylinder heads for myself.

Also, you really have the tool changes cranked up, the local HAAS dealer sets them up much slower due to the issues with tossing tools, and spindle taper damage.

Cheers.

actually i'm pretty sure that he has the high speed ATC option.

yup you were right, the HAAS machine with Side Mount Tool Change about 2.8 second tool to tool.

because, during atc the Z axis will move up and down ( it's not fixed in Z axis tool change position) and also design for the arm is shorten then the other machine.

The video doesn't show it, but each port is machined from both directions as well. 3 axis machines can be converted to 5 axis which is exactly what I did. I needed to uprade the control for 5-axis, buy a post processor, upgrade Mastercam, and buy the trunnion. I am still a newbie and true 5-axis programming is very involved and has a steep learning curve. 3+2 is very easy and convenient as well.

Ah I see... So the section has an undercut which could not be practically possible to machine on a 3axis.
How much'd you spent on the conversion and what tolerance and surface finish can be achieved with a converted 3 to 5?

The conversion with all that I mentioned above was ~$40k. I am very impressed with the tolerance and surface finish that this can produce though with any surfacing it depends on how long you want to wait :-) Fixturing becomes very important because the origin (G54) is ALWAYS set where the trunnion's rotational axis intersect.
