Circular motion

[Ashan]

Someone

please give a sample program for circular interpolation formate in Allanbradly control 8200 series

for example for Fanuc

G02 X2.Y2. I-2.

Thanks

[Marty A]

well off the top of my head,on our okuma with

a fanuc control

 

go g40 g80 g54 g90

xo yo s1100 m3

g43 z1.00 h6

g1 z-.50 f20.0

g1 g41 d6 x.50 f10.0

g3 x-.50 r.50

g3 x.50 r.50

g1 g40 x0

go z3.00

g40 g80 m19

g0 g91 g28 z0

m30

 

hope this is what you need,agin it's off the top

of my now.

For the 8400 controls(should apply)

 

G02 cw

G03 ccw

X Y I J all abolute and all 4 MUST be output for every arc

 

Arcs must be broken at quadrants

 

HTH

[Ashan]

Thanks all

Now I will manage

First time I see this control

Katie,

Im only asking but if all arcs have to be in quarters then MayDay's ex would not work????????

 

I don't think arcs have to be broken into quarters.Id like to hear your reply.

[DavidB]

"Doh" Quadrents not quarters my mistake.

[crazy^millman]

David it depends on the Ladder or Circut logic of the Machine and how it handles the arc center calucations. Some machines are writtne to understand different things for the posted code. I know on soe mmachien you can write one line of code to get a full circle just by putting a R- vaule where as on other machine you can do thsi with just as G03 X Y I J where as other machines that same line will only give you a 12 o'clock to a 3'oclock cut. That is why the psot are changeable to fit the spefic needs of what ever controller or machine you are running.

 

I hope that made sense.
