00:00:07,766
Derived Toolpaths lets you copy the parameters of an existing tool path and use it in a different type of tool path.
00:00:15,800
the next thing we need to do in our part is a Finish mill the pockets.
00:00:20,466
now we could duplicate the 2D contour tool path and then reselect our geometry.
00:00:27,166
or we could derive our parameters from a tool path that already has those selections.
00:00:34,366
Our 2D adaptive tool path for the pockets
00:00:37,900
already contains the geometry selections that we need for all the remaining pockets. We'll use that for our derived tool path selection.
00:00:48,366
the process is simple. In the browser
00:00:51,566
select a tool path that will be the basis for our new operation
00:00:56,233
right click your mouse and hover over
00:00:59,100
create derived operation
00:01:01,533
from the fly out window you can select the new tool path type. We're going to pick 2D Milling and Then 2D Contour.
00:01:12,466
now we have a new 2D contour tool path, that contains the same tool parameters
00:01:18,033
and geometry as the original operation.
00:01:21,900
now the process of creating a derived operation
00:01:25,200
automatically opens it for editing
00:01:27,466
The first thing we need to do is select a tool. so on the tool tab, go to Select
00:01:33,833
and grab a quarter inch flat end mill.
00:01:36,800
on the Geometry tab
00:01:39,566
we already have our 4 chains selected. if you should find that Stock contours is checked, please unchecked it.
00:01:46,200
On our Heights tab
00:01:48,933
We'll want to make sure that our bottom height is set from the selected contours and that the offset is set to zero.
00:01:57,333
Lets go to our Passes tab
00:01:59,833
On this page we're going to tell it we want to do
00:02:03,266
Multiple finish passes.
00:02:05,466
Let's check that the dialog opens up with additional information.
00:02:10,100
The number of finish passes is two
00:02:14,066
and the Finish pass step over distance
00:02:17,733
will be .015"
00:02:21,266
Because we might have less room on the inside of the cavity, we're going to our Linking page and adjust our Lead in values
00:02:31,266
Set all these numbers to .050"
00:02:37,200
and leave my sweep angle set to 90°
00:02:40,866
and that's all we need to change. OK this
00:02:45,733
and there's a Finish cuts for all the pockets.
