Problems with angular head

[Bjarne_M]

Hi I am new to the forum here

 

We have purchased a new machine FRAL400 a milling machine, that we have problem with the angle head..

Control we use is simens840D

and we use Mastercam X3

I have an X-axis 22000mm on the y-axis 5000mm

We have a problem with our angle head, angle head has a C axis that rotates

360 degrees, when we work in the 0 degrees stays the milling head vertical down,Then we can use this

program to mill the contour

 

N10 LOAD_TABR

N20 T="390125FRES"

N30 L06

N40 G17 G54 G64 G90

N50 Z1700

N50 TOOL_HOLDER(0,0)

N60 TOROT

N70 G54

N80 F5000

N90 S500 M03

N100 G0 Z1925

N110 G0 Y60.5 X-80.208

N120 G0 Z1720

N130 G1 Z1700

N140 G1 X-42.708

N150 G1 X372.5

N160 G1 Y-60.5

N170 G1 X-42.708

N180 G1 X-80.208

N190 G0 Z1925

N200 M5

N210 ROT

N220 M0

 

 

 

but when we turn our head 45 degrees, we must replace the x axis with the y axis

so then we must create new programs to the next angle

though the contour is the same

then we have to program like this

 

N230 TOOL_HOLDER(45,0)

N240 TOROT

N250 G54

N260 F1000

N270 S500 M03

N280 G0 Z1925

N290 G0 X60.5 Y-80.208

N300 S500 M03

N310 G0 Z1720

N320 G1 Z1700

N330 G1 Y-42.708

N340 G1 Y372.5

N350 G1 X-60.5

N360 G1 Y-42.708

N370 G1 Y-80.208

N380 G0 Z1925

N390 G0 Y-200

N400 ROT

N410 M5

 

 

 

but when we post out, the mastercam X3 using the same contour on all axes

like this

 

 

N10 LOAD_TABR

N20 T="390125FRES"

N30 L06

N40 G17 G54 G64 G90

Does anyone have experience with an angle head,

or been in the same situation that can help me with this ?

 

Thanks for all posts

[Tony35]

since nobody chimmed in i will take a stab at it

 

i dont have any angle head exp. but

do you have your planes set right?

machine def set correctly for the angle head?

post setup for angle head?

you have multi axis on MC?

 

hopefully that helps get ya in the right direction if not looks like a fun toy to play with anyway

welcome to the forum

[gcode]

Bjarne,

That is a very cool machine!!

Mastercam has a feature called aggregate head

that can handle what you are trying to do.

If you are new to Mastercam, you are probably going to need some help from your dealer to

get a post procceessor set up.

[JDowe]

No experience with this - but what about 5-axis

toolpaths limited to 4 axis output - it needs

a special post to do this - this particular toolpath looks like curve 5 axis

[GoetzInd]

Im with Gcode. Awsome machine. Do you know what these parts are for?

I agree with Gcode......we have a DMU50 and had to get a new post for it....once you index the head.....probably "B" axis your X & Y axis' flip......we had a problem in the beginning but got a fairly decent post (still in the final touch ups) from in-house.......Maybe they even have an already configured post for ya....have your re-seller contact them....

 

Good luck.....

 

BTW.....welcome to the forum

I used to work for a MC reseller and I once made a post for a mill aggregate head we just used a router post, MD, CD, All I did was change (one number) in the heading of the post pocessor and it became a mill. I can't remember witch one it was. You can compare the posts beside each other and see. It was a one (1) or a (0) should be only one number difference between then. There should be a generic fanuc router post with and aggregate head in your install. The aggregate head is common in routers.

 

From there you might need a little help using it.

Now is this a Horz machine with a aggragated head on it or the machine head has an option to program angels.

 

Looking at the first statements looks like a little post work and a understanding ow to program 3+2 should sustain what you need.

[Bjarne_M]

This part is a gearbox for a winch.

 

this is a horz machine, which we can unload and Load 7 different various accessories.

And have a tool magazine whit 170 seats.

 

We have one who has made a post processor for us

but he says that there must be something wrong with the parameters of the angular head.

it changes -X to +X when we go from milling to drilling when we use the same angels

 

We can change the post, so it's right

but we want that we can program this manually to,

 

as we were told when we had 1 day training on the machine, and the manu was that we should just write Tool_Holder (0,0) and our angles, and then should it change X,Y,Z by itself

We have contacted the seller, but is pretty poor service from them.

 

We have 2 different angle heads 1 with C axis, and 1 with a C and A axis "Tool_holder(C,A)"

 

 

only C axis

 

 

C and A axis
