SPAGETT Posted February 3, 2020 Share Posted February 3, 2020 (edited) Hello: Longtime lurker, first time poster. I was wondering if someone could help me out with a program. I have been trying to create a program that takes a profile with marks where I would like to place some webs (Figure A) and create two new profiles (Figures B & C). Ultimately, I need to produce D & E, but would settle for B & C. I've separated the results in the drawing for visual clarity, but ideally they would just be produced in-place where Figure A is. I have been trying to make it myself, but have been struggling with the logic of it. Any help provided would be greatly appreciated. The webs on A can vary from part to part and produce the gaps you see on C, so I included two sizes I use regularly. B, always has a 0.020" overlap derived from the middle lines. D & E are roughly the same as B & C, but have some added thickness on the ends of the hollow side of the cavities--not on single leg cavities. They increase in thickness by 0.005" for a distance of 0.050" and then taper back to the original thickness over the same distance. Also, the transition from the thicker portion to the taper must have a radius with a minimum of 0.010". I am really grateful for any help with this. Thank you!

BIGAL Posted February 3, 2020 Share Posted February 3, 2020 Only 1 suggestion this is a hard task, as you have 3 lines for break point, you can use trim pick outer lines, then use the " F" fence option on the middle line it will trim out the gap. You don't mention how the 3 lines are created, if some form of manual method then the middle line is not actually required. Looking for all the 4 line segments is a bit daunting but can be done to add the fillet. Quote Link to comment Share on other sites More sharing options...
SPAGETT Posted February 4, 2020 Author Share Posted February 4, 2020 Thanks BIGAL. I suspected this was probably a difficult thing to program--I was just hoping that I was missing some simple solution as it related to automating. Some of my larger profiles can take an entire day to produce Figures D & E. Yes, the three lines are created manually. For automation, the middle line probably isn't necessary, but I include it because it is currently what I use to manually create my initial Fig. B/D parts. Then use the outer lines to produce Fig. E.

BIGAL Posted February 5, 2020 Share Posted February 5, 2020 Can help auto that step, something like pick line near corner I do a routine then know direction is away. Enter offset 0.0 is start corner (getdist. Pick other line. It looks like the line gap is fixed so draw 2 lines = gap between two lines picked, trim gap, fillet both trim lines. Have some other stuff in front for me maybe someone else will jump in and get started. 1 Quote Link to comment Share on other sites More sharing options...
SPAGETT Posted February 6, 2020 Author Share Posted February 6, 2020 I appreciate the offer BIGAL. I am currently working on something that will do just that for the time being, until I can comprehend the steps to create the profile automatically.
