5 AXIS OKUMA PROGRAMING

[OTOMMYO]

I am trying to wirte program for a 90 deg head on our Okuma 5 axis mill, and when i post it it gives me xyz moves as if im milling top plane.

I write the program in the side plane and everything looks good till i post it and xyz are wrong. Anyone have experance with this? please help i am using X2 MR2

In V9 you had to use the aggregate chook for these types of operations. I would guess the same for X. Sorry can't be of more help. One of the guys will step in and help ya out. Go in your chooks folder and see if it's there.

Ok to ask a dumb question,

 

Why do you need to use an angle head when you have a 5 axis mill?

[OTOMMYO]

not a dumb question i should have been more clear.

 

It is a Okuma MCR 25B Double Column with a Work Envelope of 14’ x 8’ x 6’ (auto change 90 deg. head)

 

tried the chook but x2 wont accept that version.

I'm not sure about that machine, but if you are working from the top plane but want to cut the side of a part. On the first page of your toolpath params you need to set your planes tab to top, right side, right side that should do it. (right side can be replaced with what ever side your tring to machine)

 

Hope this helps...

Still wont post right. when the 90 deg head is on and i want to mill a pocket on the right side it should post it like this....

 

G0 H1 Y1.(Y1. CLEARANCE PLANE)

G0 X0. Z0.(CENTER OF BORE ON RIGHT SIDE OF PART)

G1 Y-1. F10. (Y-1. DEPTH OF POCKET)

X-1.

G3 X1. I1. J0.

X-1. I-1. J0.

G1 X0.

Have you by chance contacted your dealer and see if they have it in the post you have and may just need to turn on an misc integer to get it to post right. From what I remember there needs to be a combination of a router post and mill post to use the aggerate chook the correct way. I know post pretty darn well and this is one area I leave to the experts.

Selecting an aggregate head

Both Mastercam Mill and Mastercam Router support aggregate or angled heads. Depending on the capabilities of the specific head, they can have several tools mounted at once, swivel or rotate to different positions, or can be fixed at different angles. In general, aggregate heads can be used for any type of operation that is supported by their individual tools.

 

Before you can select an aggregate head in an operation, you need to define it with the Machine Definition Manager and add it to a machine definition. Tell Mastercam about the geometry of the head and its tool stations, its rotary and tool change capabilities, and other properties. At this stage, you can choose to either set tools in the tool stations or leave them empty.

 

Follow these steps to use an aggregate head for a toolpath.

 

Select the machine definition and desired toolpath. In the Toolpath parameters tab, right-click in the tool selection window and choose Get aggregate (if you are using Mastercam Router) or Get angled head (if you are using Mastercam Mill).

 

The Aggregate selection dialog box appears. Use it to select a tool station from the available heads.

 

Click on a head to expand it and see the individual tool stations.

 

Tool stations which are properly oriented for the selected geometry are shown in bold.

 

Click on the desired station to select it for the operation.

 

If no tool is mounted in the tool station, right-click on the station to add one. You can either get a tool from a tool library, or create a new tool definition.

 

 

When you choose OK, you will return to the Tool parameters tab. The station name will appear in the Tool name field, and the tool itself will appear in the tool selection window.

 

If necessary, select the Axis Combo button to choose the proper axis combination that has been defined for the aggregate head.

 

Continue entering your other toolpath parameters as you normally would.

 

If you need to use the same tool and tool station again in another operation in the same toolpath group, you can just select the tool from the tool selection window. You do not need to complete all the other aggregate selection steps described above.

 

HTH get you going in the right direction.

The post also has to be able to support aggregate heads as well

We have a local Mastercam user with a MCR double column, using the 90 degree head. They are Mastercam users as well. I can get some info from them on Monday

[Greg Williams]

Ah Double Column now I see.

 

I find the best solution is to use Slope machining

 

There are two command formats:

(a) (G69 [X_] [Y_] [Z_] P_Q_R_ ]

( [G49 H1]
