it looks like no circle but some spline,

look at replay:

and if this is the case I am talking about and you dont see CIRCLE - everything is alright and dont even think about G02/03 Smiley Happy

In the operation dialog of the tool path you are post-processing, double check that Motion Output Type in the Machine Control group is set to Arc - Perp to Tool Axis.

as juraj said, if there are no CIRCLE moves in the internal toolpath (I use: Right-click on operation -> toolpath -> list) then you will never get arc output.

Note if you are doing this for high speed machining, you probably WANT G1 output (although I am no expert, I have heard that the HSM algorithms have to "stop" at arc moves, then restart again after the arc, which will slow down processing/machining)

What if we want G2?I forced G2 (PB) output in circular move and reduced arc length,but still getting G1.Internal toolpath does have circular output.

If the internal toolpath has CIRCLE and posted outpot is linear moves, look at minimum arc length and radius values in post

Toolpath arc is much much larger then set minimum arc length in PB,so there should be no problem there.I used library's  Siemens post,if that means something in this case.

What is the operation type?

 

Another possible problem is the plane of arc and machine kinematics.
