In the same vain... what type of mill would make a good 5 axis
conversion??
I just bought a large rotary table with an integral servo drive and
motor. It has a 12 diameter slotted face plate and must weigh at
least 6-800 lbs.
I'm looking for suggestions on what VMC might be big enough to

Or am I on the wrong track. Should I just look for a 5 axis mill with
dead controls and convert it?
Any suggestions?

Seems to me that
My 12 inches CNC rotary table weighs closer to 250 lbs.

I am sure there are other machines that can do the job. But in any
event it is going to use a lot of money and/or time to get it to go; 5
axis is expensive.

This one weighs considerably more. I can pickup 250 lbs, but I had a
hard time sliding this one once I got it in my pickup truck bed.
We used an engine hoist to load it as there was no way that two of us
could lift it.It is programmable and has some type of air lock
device in it also

agreed - the kinematics is in the g code program - just having the machine
control the axes is enough to be able to cut 5 axis parts

I was under the impression that the kinematics had to be written in EMC2 for
the coordinated movement between all the axes to function
that is exactly correct for conventional 4/5 axis control
if you want to simplify the programming you can develop kinematics for the
machine
this will allow simple programs to do complicated motion - it is not
necessary for 5 axis motion - sometimes it is not desirable
to get where you need to
Hi Dave:
So when are special kinematics needed? When are they not? Are you
rotating your gear blank about AB to establish the desired cutting plane,
locking it in that position, and then cutting with XYZ?

A cam system will still need a 5 axis post processor to be able to output 5
axis gcode.
It will need to be matched to the machines kinematic capability.
The simplification of programming a (in the control) kinematic module allows
is plain operator/programmer readable code.
If you have a program
one example
if you have a XYZAB machine like my cinci (AB tilts the tool) a kinematics
in the machine allow me to program a drill cycle, use W instead of Z, and
drill along the axis of the tool no matter what angle the tool is tilting.

As I hand code and can therefore control direction the rotaries move I can
cut against the play/backlash inherent in the cheap rotaries I use, often the
B axis will be locked though for greater rigidity.
Im mostly cutting light weight brass blanks though.
A reason I hand code is I cannot afford
I am interested in adding a trunnion and rotary table to my existing
machining center. The frame is excellent but the control is dead so I was
thinking about using EMC2. Is there someone out there that has a successful
running machine that I could talk to and get me going? Also is creating the

it would be a simple thing to modify the kinematics to do a tilting rotary
table

on a mill with stacked A on B, I hand craft the gcode though, as it
happens to suit the work I do.
