Machined Machining

Hello everyone,

I dry on a curved machining part with a precision of 0.1mm.
I can't find the function for my full bridle to fit the curve I sketched (in red on the picture).
I found 2-3 questions in the same genre, but I can't transpose it to my problem.

Attempt n°1: I manage to make a gable, but afterwards, the holes are not suitable, so this order of the functions is not good.
Attempts 2 to 4: unsuccessful attempts
Attempt n°5: I manage to prepare my machining in a flat version, but I can't get the back of my part to fit on a gable on 1 axis only.

Has anyone ever faced this problem

Thank you in advance and have a good day to you

Hello @arkam3D ,

Your description of a room " curved on a single axis " lacks clarity...

I see three possibilities:

  • the " outer " face on the right is spherical: it is sufficient to replace the rectilinear segment by an arc of a circle in the " Revolution1 " function;
  • The outer face is cylindrical: I propose as a first function an extrusion of a sketch with the curve in the form of an arc of a circle. The " inner " shape is then obtained by removing material by revolution;
  • the part is generally curved, both outside and inside: simply take your model and apply a Flexural type deformation (Insertion > Function > Flexion) to the " Revolution1 " function with the appropriate radius.

In all three cases, I reduced the radius of the curve to 500mm to better visualize the result. Simply change this value to 2200mm in the appropriate function.

It remains to be understood what " suitable holes " mean: axes parallel to Z, axes normal to the outer face, to the inner face...?

Hello

attached is a version with two configurations, the 1st is with the " foldable " version for cutting and the second is the " Finished Part" which does not unfold but is for the MEP so the increment in an ASM

Hello
Thank you @ac_cobra_427 and @m.blt for your answers.
Indeed, I explained the history of the holes badly.
The solution I was looking for was "flexing" by making the holes before the flex.
I'm going to see a little bit how this function works, which I didn't know about.
