160 SolidWorks Sheet Metal Tutorial: K-Factor; bend allowance; calculating manual/by table/ software Video Lecture | SolidWorks: Essential Training (All Commands included) - IT & Software

welcome to our number 160 this tutorial
will be a political tutorial but it will
be important to Toria to understand the
logics behind the sheet metal bending in
order to get an accurate sheet with
those dimensions in this tutorial we
will talk about the sheet metal please
locate the allowance menu and then talk
about different materials calculating
the k-factor and incisional or k factor
values and then at the end of this
tutorial we will see some programs that
calculate the K factor
so there we have a new bot file start
with the plane and draw a bishop all the
fine detail will give it some dimension
you
very good symmetry relation and now Mack
sheet metal beam from this be shaped by
be this large here give it a length of
150 as you remember we talked in the
early tutorials that we will talk later
about the paint allowance over here so
we will discuss this menu now if you
open the build allowance you will find
money with it calculate giving allowance
you have been table which will be the
topic of the next lecture and decay
factor and then we build allowance which
is a longer equation that include the K
factor we will look at the format of
that allowance and then been deduction
and bin calculation the last to the
almost based on experience and so we
will discuss more the first three
options and then in tutorial after the
next one we will talk about the gauge
table
we are repaired by given table and K
factor a saving time method
so well for now pick a key factor as you
remember in the previous tutorial we
said this will be a stainless steel
sheet and we assign point four key
factor and we will see how we came to
this value and then when you are done
click OK
we sit on the tree you will get you will
get the Cutlass and the with them
and we splash but if you want to get
back to the theoretical values you
should it be cheap with the over here
and there you combine or adjust the
allowance but you cannot pound it and be
this much reason for that we said it
considered the whole war in the same
type of leader one thing which it
went on and let's say just supply a
material to make clear that we are
dealing with a thin sheet
why there is a bit allowance the reason
for that there are different materials
and as we said when you've been a sheet
of aluminium will not give you the same
dimension as building a sheet of Steel
also on will be covered also the type of
breasts you are using if you have a
person with a bigger bending radius also
that will affect for example decay
factor
the keypad is the ratio between the
natural line and the thickness of the
sheet metal as we can see here here we
have the neutral line and here we have
the thickness is T over there the place
of the neutral lumpkin can change
depending on the bend radius and the
dent
Anke now again go to the sheet metal
understood about the next given
allowance the bit allowance is kind of
more accurate way because but use the
complete formula which we can see it
over here event allowance is PI
multiplied the radius the bend radius
plus KP a over 180 so this is the
formula of the beam allowance in one of
the next tutorial we will talk about the
gauge tables a popular method in the
industries which combine both methods
has a tendency to get back to live okay
now you may think it is complicated
process but it is not because the values
of covertly calculated for the most used
sheets they are bending tables we will
talk about in the next tutorial and also
there are even a faster way called gauge
tables will be possibly topical into it
after the next and then if you go to the
Wikipedia you can read more understand
this topic and you will notice it is so
I recommend you to read this article
about bending it will give you a wider
understanding about sheet metal bending
and here you will see the types also do
you have the bunch and at the end you
will see more detail about per click a
packed and then allowance as you said
and then you have a general table that
we may use for the most standard cheap
metals of aluminium and steel and here
the value of the K factor you can pick
according to the radius then radius for
example we have this our sample this
that will be values over there we have
give them radius per second and
thickness is 1 millimeter material is
steel you can find the value 18.4 but
also as you notice here that as you
notice here when Bend radius is
increasing compared to the thickness the
value of K pass is increasing as well
and the hardness of the material
we think the key factor between of the
street is Colin Dominion
you
here is an example for a sheet metal
industry example four fingers and they
have also their or completely being on K
factors we can start it here and you go
to the bin deduction you can see very
easily these values over there and
calculate a key factor as you remember
we use steady speed our sample remains
in thickness on millimeter and the a
side and this angle identify the a side
on six 126 then calculate and here you
will see you get after it is close point
for every remember we said if you
increase the building radius that what
enquiries the K factor here you have the
bending radius let's make it two
millimeter and you will know this decay
back to the cane point five so on you
will make a point for from one point six
now return to our intervene voting
machine affected by the values there you
can change it according to the website
or you can keep it going for already 38
and you know from where I've been
38 click yeah
you
