2D profile+depth cuts+rest machining

[SlaveCam]

I need to cut a 2D profile to a cylinder using depth cuts. It takes very little material at the beginning, so I'd like to apply the "rest-machining" method using a stock model to a simple 2D contour to eliminate air cutting.

Is This Possible?

Managed to do this using waterline HST toolpath with the profile extruded as a drive surface and a boundary containment, if there's an easier way, I'd like to know...

use trim

use trim

Ive always felt that trim is the least use routine, but it can work wonders

I use trim all the time. Since using mcam area and dynamic mill I use it way less but previously it was the only way to get the desired path.

Also don't be fooled by the must use a containment boundary for Area Rough and Opti. With a good stock model these toolpaths work, but have to be aware of the possibility of getting some odd results.

I would take a look at the HST Project toolpath.  You can have it do multiple depth cuts and trim to a stock model.  the source for the cuts can be curves or a contour toolpath (any toolpath really).  You won't have cutter comp but if your using the trim toolpath you won't have correct cutter comp output as well.

 

 

if you have the multiaxis curve toolpath that makes it easy to trim cuts to a stock model as well.  Works for 3, 4, or 5 axis machines.
