I have made some punches for sheet metal and this one seems to be simple but it has me stumb. Please help.
Its 50mm in Dia a 5mm lip a 28mm outside rad cone and a depth inside of =/- 8.5mm then there is a 12mm hole
Solved! Go to Solution.
Sorry I also then have to make a FlyPress tool for it which is not such a big problem but if you have some ideas it would be great
I hate to tell you that you are doing it all wrong - but we can correct that.
First of all, do a search on Punch and/or Dimple here.
Start from a sheet metal template.
Turn off autoproject of centerpoint - or delete the autoproject from any sketches.
Create a rectangle and then Face feature.
Start a new sketch on the face of the part (must be on the part, not on Origin Workplane.
There must be a sketch point in your first sketch (no projected origin point or other projected geometry).
Lets start with just a Cut circle with a size dimension (no location dimensions - the sketch should be underconstrained).
Get that working and then we can proceed.
This may help you ..
Hope I am doing it right ?
Note in your image that the edges (yellow) were autoprojected into your sketch - you don't want any extraneous geometry like this in your sketch. I recommend turning off autoproject edges in Tools>Application Options>Sketch tab.
Thanks for that. it helped a lot. I think I still want to run with the help that JDMather is giving me so that I can learn from a expert. But thanks again.
It appears that you have a Point rather than a Center Point at the center of your sketch.
Punch tools must have a Center Point in the first sketch (this is used for placement of the Punch feature).
(see attached image for technique to change the Point to a Center Point).
If you want to be able to change the size of your Punch it would be a good idea to name the diameter of the circle (refer to the attached image). In any case, dimension it.
Create a Cut feature with the circle.
Communicating this process will take a bit more work because I can't attach image files and you are using an earlier version of Inventor so you would not be able to open my Inventor file.
JD is very good at what he does I just thought a video would be a good visual for you the steps in the video are the same steps JD is giving you.
