My problem is to model slideway for empty cans. Main problem is in round bars.
I need to have good models of bars for CNC bending bars machine.
I tryied to use a combination of:
loft - when bars goes only in Radious
loft with twist along the path - when can is rotated along the path.
But it do not looks good- i obtain not smooth regular shape.
What operations i should use in solidworks to make it in the proffesional way.
The can inside do not may to stock- so the profile along the path shall be always the same.
I'm adding the pictures of oryginal guide which i must modydi for inner can.
and my test-sample creenshots with bad method of modeling(not smooth shape)
Why don't you try using composite curve. After making the path that consists of several lines use composite
curve to create one path and than use the sweep.
Unfortunately flex command (+ twist option) do not give the tangent model.
I"m obtaining the same result with no smooth tangent shape. I' trying now with loft of 2 circles with spline control (tangent relation can be added) as a centre axis.
the problem is that while drawing path ( in the "twisted" part - it is so many freedom of movement for the splajn.
I make the strart and the and of the splain tangent to straight lines - but the middle of splain is still not fixed.
when i put 6 these splains with no mathing dimmensions the can may stock inside.
If I undestand you clear....
I shall draw six main composite paths for each bar?
Maybe if that doesn't work you could make a model that is straight and use the flex command. Under flex use twist. Choose the plains around which you wanna twist. This will simulate the real conditions.
howzit gave it a bash
you can controle spline pretty well with sketch points
you get vey good control
Thanks for fast response.
but it is fine for one bar.
When i draw 6 splines for each bar- they shall be in the same distance between each other
along the all path
(always the same place for can)
it is hard to place 6 similar bars.
. i will try this mathod and tell you if it was worked.
Ok guys! Thanks a lot for your sugestions.
Finaly i did the smooth shape with "parrallel" bars among all the path with loft operation.
I lofted - Two round profliles and give the moddle path (3d sketch - splajn with only one point to control -which i fixed into auxiliary sketch, begining and the end tangent to existing bars.
