You mentioned that the opener could be used on larger cans than can be cut in one cycle, and that you may wish to improve on this. Is the magnet capable of lifting up the lids of these larger cans? In the course of cutting, will the lids break leaving jagged edges as a result of improper support due to a weak magnet? Additionally, you have the magnet listed as being cast.

You have the blade listed as being stamped. Would stamping provide the stiffness, and edge needed to cut metal reliably for any length of time? | You have the blade listed as being stamped. Would stamping provide the stiffness, and edge needed to cut metal reliably for any length of time? | ||

You have a very full FMEA, with a failure and effect for almost every part. However, is it not possible that a single part can fail in more than one way? For example, couldn't the switches falsely trigger instead of merely not triggering at all? Could this be represented in your FMEA? Additionally, some comments on you FMEA findings would be most welcome.
Your component listing is a little sparse, picture wise, however, you have provided a very nice open shot of the complete gear train. It might be useful if you could label the gears and refer to them in your Listing. It might also be useful for you to calculate the speed reduction, and torque increase that the gears provide, at least up until the intermittent gearing begins, as you mentioned in your improvements.
