00:00:00
hello everyone, today we’ll talk about
00:00:03
trajectories that follow the bends of the part,
00:00:06
such as smoothing, processing along
00:00:08
the flow, these trajectories are 2d 3d and have
00:00:11
a lot of power, and let’s start with something simple, even
00:00:14
primitive, draw two non-
00:00:16
parallel lines and process the
00:00:18
space between them trajectories
00:00:20
smoothly for almost all the
00:00:24
trajectories under consideration we will need two lines
00:00:26
between which processing will take place
00:00:30
[music]
00:00:40
when selecting a chain, always select them
00:00:42
so that the vector faces in one
00:00:44
direction if you make a mistake,
00:00:46
use the change direction button
00:00:49
[music]
00:00:53
after selecting the first chain, click on this
00:00:55
button and then start choosing 2 otherwise
00:00:59
the program will try to understand them as
00:01:01
one element, we have selected a chain, selected a
00:01:04
tool and look at the settings
00:01:06
of which there are almost no here, select the step,
00:01:09
select parallel or perpendicular to
00:01:10
the lines, processing will take place, then
00:01:14
we see incorrectly labeled
00:01:16
settings
00:01:17
allowance is actually the processing depth
00:01:20
and fast depth is clearance as I
00:01:24
tried no matter how to adjust the trajectory so that the
00:01:26
cutter did not go beyond the boundaries of our lines, it
00:01:28
didn’t work out so this trajectory is
00:01:30
well suited for the top of the workpiece since the
00:01:33
main task there is to properly
00:01:35
process the surface between the curves
00:01:40
[music] the
00:01:45
next trajectory is also somewhat
00:01:47
dubious linear
00:01:50
[music]
00:01:58
too strange signature of the parameters, but these
00:02:01
two more settings for cutting by plan 1 and
00:02:04
cutting by plan 2 1 and 2 refer to
00:02:07
our first and second lines and something
00:02:10
interesting can be done thanks to it,
00:02:12
although this function is buggy
00:02:15
[music]
00:02:44
now I’ll move plant so that it
00:02:46
intersects the coordinate 0 you can
00:03:40
extend the approach and
00:03:42
retraction, you
00:03:53
can also adjust the processing depth,
00:03:56
the maximum step and finishing pass
00:03:59
[music]
00:04:15
in general, this trajectory covers all the
00:04:18
needs for smoothing in 2d let's move to
00:04:26
3d I
00:04:27
will draw our nice curved part
00:04:29
by extruding the profile along the
00:04:32
guide
00:04:33
[music]
00:05:00
I will select the profiles of the part then indicate its
00:05:04
path
00:05:17
Now let’s select the type of trajectory, we have two
00:05:21
options: flow
00:05:22
and smoothing, let’s check how both of them
00:05:25
work in the flow trajectory, select
00:05:28
our surface and click on the button with
00:05:30
lines,
00:05:31
these lines will tell you how and in what
00:05:33
direction the processing will be carried out,
00:05:36
that is, here we select the longitudinal or
00:05:38
transverse processing directions
00:05:40
as well as the side from which this processing
00:05:42
will begin, we will select the cutter for the sake of oral and
00:05:48
indicate the step, everything is quite simple
00:05:51
[music]
00:06:06
now we will take smoothing
00:06:08
[music]
00:06:12
we will select the processing surface then we
00:06:16
must definitely select the lines between
00:06:18
which and along which
00:06:21
the chain will be selected from the curvature of the trajectory, we will
00:06:24
select along the edge body selection method
00:06:26
you need to use edges
00:06:35
here there is a small glitch I can’t select
00:06:39
one edge confirm the selection of the chain and select the
00:06:42
second edge
00:06:43
the program will consider that it is still
00:06:45
one chain so you will have to first
00:06:47
select one edge accept then
00:06:50
add the second as I am doing now
00:06:52
or create curves on edges, which
00:06:55
is a more competent solution, now
00:07:00
we’ll choose a cutter with a
00:07:03
step in the longitudinal or transverse
00:07:05
direction and adjust the transitions
00:07:09
[music] the
00:07:42
result is generally the same
00:07:44
[music]
00:07:47
however, let’s now complicate the geometry
00:07:50
of the part, I’ll add radii
00:07:52
and see how to deal with it now
00:07:54
our trajectories
00:07:58
[music]
00:08:02
and
00:08:04
[music]
00:08:09
we select new surfaces but flow
00:08:12
trajectories and look at the direction of
00:08:14
the lines
00:08:15
[music]
00:08:27
for each surface
00:08:29
the lines have their own direction and often
00:08:32
get together and this is still a good
00:08:36
result. If I had done this detail in
00:08:39
solidworks and then moved it here, I
00:08:42
would most likely half of these lines went
00:08:44
perpendicular to the main direction and
00:08:46
when calculating we would get an extremely
00:08:48
strange result, or in general
00:08:51
the trajectory would throw an error; however, even
00:08:53
now I’m leading the trajectories unhealthy. Now
00:08:57
we’ll try smoothing, since the edges
00:09:00
that we used in our
00:09:02
trajectory, we have a heresy of radii, we need to
00:09:04
create a new one and here, if you don’t
00:09:07
need great precision, you can do the
00:09:09
following:
00:09:10
select a spline and approximately repeating
00:09:13
the bend, draw lines on both sides
00:09:16
[music]
00:09:37
select them
00:09:39
[music]
00:09:51
already quite well
00:09:54
and
00:10:02
now let’s do everything scientifically,
00:10:04
select the bottom part of the parts and create a
00:10:07
curve on edges
00:10:08
[music]
00:10:20
and now we’ll extend the side lines a little so
00:10:23
that they extend beyond the border of the part
00:10:26
[music]
00:10:42
and shift them to the radius of the tool
00:10:46
[music]
00:11:02
select them and recalculate the trajectory
00:11:06
[music]
00:11:16
now everything looks great, also in
00:11:19
this trajectory, unlike the streaming one,
00:11:21
you can use limiting contours
00:11:25
[music]
00:11:44
and we’ll talk about similar trajectories of multi-seeding
00:11:49
processing next time, but
00:11:51
for now, thank you for your attention, like the
00:11:54
video if you liked it
