We are using a 3 axis Leadwell machining center with edgecam for cam software. When machining a slope from one flat surface to another the only success we have had is using parrelell lace and a ball nose end mill. This is impractical because the run time is enormous if a reasonable finish is achieved. Any suggestions would be appreciated.

If the surface is flat in 2 axis', you can re-orient the part and face it. If the surface is not large, you can use a form cutter to achieve the angle. Other than that, if you wish to 3d mill, you are stuck with that single option.

If you have conventional milling machine tool (traditional Cincinnati) you can fly-cut the flat surface with a form tool.
Fly cutting is a traditional way of machining a flat surface with a blend in radius, other ways are to use a shaping machine or a planning machine depending on the size of the material.
You have not given any more information so we can only give limited feedback.

Thank all for ideas. it seems realigning the part and cutting slope as a flat surface is ideal. I envision drawing stock with the top parrellel with the surface and putting a CPL aligned on a corner and picking the feature manually. Does that sound practical?

If the part is completed using two separate setting you still have the problem of blending in the two separate cuts, but if it is not critical this may suffice. Generally speaking operations should be completed as far as is practicable in the same setting.
Hence when turning a coupling for instance the whole part should be roughed out both sides and then the back end completed (because of its open tolerances) and then the front flanged end last. This will ensure the Bore, O.D. and spigot (all precision tolerances)will be completed in the same setting as well as the scribed PCD for the driller. The fitter when aligning the coupling then will have a true surface to clock the OD when setting, and this reference is true to the spigot and bore.
Only you can decide if a double setting will do.

A few questions:
1. What is the approximate distance along 'X' and 'Y' for the sloped section?
2. Approximate slope angle?
3. Material?
4. Current machining parameters (SFM, IPT, DOC, WOC) for rough and finish?
Thanks.
