Swarf 5ax would be best done using chains

1 operation each for front wall, and back wall
select bottom chain 1st to set tool offsets, top rail to set tool tilt or rotation
keep the chains simple and short when learning, long contours can have sync problems

Parameters
comps ON - "Computer"
entry/exit - both on and set the same, length=10, thickness = 2 , height =0, pivot = 0
depth cuts and multipasses work similar to contouring operations
Chord height affects the surface finish, big # = big facets, suggest 0.001mm or less for finishing

geometry
4 axis = ON
chains ( bottom contour 1st, then top)
surfaces = controls the tool depth on the cutter edge instead of through the centre line

I also have made progaram swarf5axis but it is only for finish cut,i like to making program rotary simulator cut 4 axis,but not succefull,see line below:

Are you saying that the picture does not look good ?
1- the verify looks very rough , big facets etc ?
or
2- the verify picture does not match the mastercam model ?

if #1, your verify settings are incorrect, try using "true solid" and high quality not speed, tools should be "as defined".

if #2, your comp settings are wrong, only use "Computer" for any 4 or 5 axis operation, using "Off", "Wear", "Reverse wear" and "Control" will not give correct code. Unless your machine is capable of adjusting comps in 4-5 axis, most will only do the 2 that make up the tool plane (is XY,XZ,YZ). The other just controls the depth.

The settings I suggested, I used on your session, and the verify shape ended up the same as the model.

Note--
swarfing--is best done with wireframe, not surfaces.
Depth control- let mastercam control that with a surface for the floor- your tool won't gouge the part. "Use bottom rail distance" is good for having the tool project past the lower contour, it will not control the leading or trailing quadrant points on the bottom of the cutter

Thanks for your help me,swarf wireframe i have made is only for finish cutting,can you help me how to cut the cylinder shape.i have post immage after manifacturing for you check:http://www.mediafire.com/?cwnf3kgmiow
thanks!
