morph between curves

[HEAVY METAL]

The tool looks like its gouging walls on the od channel in a few areas. I don't know why it is not staying between by two curves. I'm set to 4 axis output. B axis horizontal. I put file on FTP (31620-01001-spiral)

Too big to post here. I.ve tried different settings but not getting the path to stay in channel

morph between curves will try to cut the whole surface/solid face you select, not just stay between the curves. the curves are just used to define the 'pattern' of the stepover. Try using a 2D containment boundary under cut pattern, or set some check surfaces in collision control and tell it to trim the toolpath between gouges, and set your linking parameters for gaps to follow surface

Check out start and end margin settings also.

I used the check surfaces and that helped alot. Still trying to tweak is som more. My plane right not is to rough out down the middle with curve set to 4th axis output. then use the morph to finish .The crunch time with the check surfaces added is pretty long I noticed.

sometimes copying the surface and trimming to your curves is a fast remedy?

I may take a set of surfaces and turn them into a net surface. Then you get some nice options for toolpaths doing it that way. Times where I want to flowline a fillet for instance. I have made a model with .01 bigger radius than the part I am machining for everything except for my fillet. I then come back and then make a surface from the 2 joining walls .025 bigger than the fillet and the fillet surface or surfaces. I then create my edge curves and then covert multiple chains into one for a top spline same for a bottom spline. I then have my along and cross chains and then done. A little bit of modeling work, but the toolpaths that come from it are easy to run and control.
