Sweeping Solids?

[sanstey]

Hello All,


This is my first post and I am a ProE Newbie so please be gentle

My question is: With ProE can an already created solid be swept along a trajectory to create a new solid?


My reason for requiring this is that I need to create cutter path geometry and I cannot think of any other way to do it.


All help appreciated.


Thanks Steve.

sanstey if you are talking about pro/ manufacturing. i think there is an option for doing this kind of operation.


and if this is for solid modeling. then yes we can use already made sweep feature to make a new sweep feature

Look at it this way. Assuming that the cutter is a rotary cutter, you can use a sketch of the cutter (e.g. a ball nose cutter will have a U-shape) and then seep the sketch. Creating a solid may not be necessary.

Thanks to you both for your comments.


For clarification I am trying to model this feature and am not using the manufacturing module.


Unfortunately sweeping a sketched profile does not work. Though it's very difficult to explain why without pictures.


I will create some pictures and get back to you.


Thanks


Steve.

The sketch should be NORMAL to the start point of the sketch. Preferably make the sketch Internal to the Sweep Command.

I am having a similar situation, I think...


I want to model the slot that would be created if a ball nose end mill was run along a ZX curve, but remained vertical. Hard to explain but I will try.


The end-mill starts at X 0.0 , Y 0.0, Z -1.0, then while staying vertical, does a radius which brings it to X 1.0, Y0.0, Z0.0. Travels to X2.0, then radius down to X3.0, Y0.0, Z -1.0


Making any sense?

Here's a picture of what I mean, I want the blue end-mill to follow the red curve

Redraw the curve at the center of the ball mill's sphere and make a swept cut; the profile would be a circlecentered about the new path and normal to the trajectory.


To move the curve, you would simply need to move it upwards in Z+ by the radius of the ball mill.

Here's a picture of what I mean, I
want the blue end-mill to follow the red curve
Model the cutter. define a point at the nose of the
cutter.
Define the cutter path. Define a mechanism for the cutter
to follow the path. Create a solid (The solid will be
jagged and can give you jagged surfaces even at a quality
10)
Subtract the solid thus created from your part.
There was an earlier discussion on a similar topic that
is to get a helical MILLED groove using an End mill
cutter.
A study of the link will also help.
