Angle style for 3 + 2 machining

Jaanyaar — Thu, 16 Nov 2023 17:07:37 GMT

Hi!

This is a simple 3 + 2 machining including 5 toolpaths spaced by 72 degrees.

The order in PowerMill is so:

1. A0

1_1. A-72

1_2. A-144

1_3. A-216

1_4. A-288

But post processor outputs angles in different style:

1. A0

1_1. A-72

1_2. A-144

1_3. ~~A-216~~ A144

1_4. ~~A-288~~ A72

A piece of code:

TOOL CALL 13 Z S4000 DL+0.0 DR+0.0
M3 M8
L A0.0 FMAX
L X25.192 Y0.0 R0 FMAX

...

Which setting in post processor makes the order of angles similar to PowerMill?

Try the angle roll over

Thanks!

The order of angles in the above example is clock wise (-).

If I set it to (-360;0), then all angles are in minus, even for other examples that the order of angles are in counter clock wise (+). Not suitable for CCW direction.

If I set it to (0;360), then all angles are in plus, even for examples that the order of angles are in clock wise (-), Not suitable for CW

If I set it to (-360;360), then half are in plus sign, half in minus, like the the example above.

More help is needed.

Have you tried adjusting the angle style?

You might need this set to mathematical or relative.
