Hi,
I would like to correct my statements made earlier in this thread.
"It seems that our friends at Cypress have something missing what SolidWorks' developers had for years. And they used NX's parasolid geometrical kernel for it."
Edit: As of today, NO, SolidWorks cannot make this swept-cut feature as it should look like in the real world. It can only do simple shapes as long as the helix doesn't go fully around the cylinder or in other words if the pitch is only 1/4 or less and the development of helix angle is very shallow to none. This development angle is used for placing the solid tool body to be used for cutting the sweep. Here is what I found on youtube video clip for a simple shape and also I noticed the path was used is not even a helix and there is solid tool(conical shape) body's side face is parallel to the main cylinder's axis showing no development angle at all as it can be seen from 0:52 thru 1:24 in the video.
In real world the grinding wheel's side face is placed at an angle to create the cutting edge in the flute and that's why an endmill has a slight curved shape in the flute. Normally it is matched closely with the development angle of the helix for a few reasons. By doing so the cross section of the cut is not a planar curve and it is 3d spline. It is hard to visualize but it can be observed carefully in real life when a tool-grinder resharpens the endmills.
I hope NX folks add this capability soon in the future release.
Regards,
SSC
