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

I have a manual universal head on a 3 axis mill with a Fagor controller.
To do a job like yours, I would change the plane. (Fagor G49 C45) and use the same code for each face.
