I understand a single device design can be made simpler. However, like I said, this is using a template design that can be changed by changing the radii. This is where I see the problem. The design is for Sewing Machine stitch pattern cams. The way I have it, all I need to do to change the stitch pattern is to change the radii, fix the connector conic curves and save the new cam design. There are 2 layers, each with 24 active lobes and 24 connector lobes. The two layers are offset by 7.5 degrees. I think you will understand that recreating the whole design for every different pattern couldn't be simpler unless I could import the radii which I generate in a spread sheet. I can't predict what lobes do what for future stitch patterns. This particular pattern is for hearts. The top layer changes the direction and length of the fabric movement for each stitch while the bottom layer changes the left right position of the needle for each stitch. Each rotation of the cam is one pattern and consists of 24 stitches. The cam followers are 5mm in diameter so the conic curves need to compensate for that to prevent premature changes. Also, the follower can get stuck if the transitions from one lobe to the next is too great for an increasing radius. The cam followers move in an arc which you can see so the location of the lobes move as the radius changes. I've put a lot of effort over the years into this design with many iterations. With it, I can create a new cam in a day if I don't run into problems. I must say I've run into many problems too.
