Tips for making acog that interacts with a linear pattern.

Hi!

Sorry not sure if this is the right place to ask so please move if need be.

I'm running fusion 360 and would appreciate some advice in order to realise a design.

I have a plastic sheet with a uniform series of gaps formed in it. I would like to laser cut some discs that will interact with the holes in the sheet to pull in through a mechanism with one full rotation.

I was wondering if anyone can point me to some tutorials or tool documentation that would help to achieve this in fusion360?

My first thought was to make a linear pattern that mirrors the gaps but with some tolerances, then transform to a circle.. not sure if this is the right approach?

Thanks in advance for any constructive advice.

All the best!

Hi,

Create a screenshot and show what you want to achieve and share the file.

Rack and pinion.

Hi thanks to both of you for your replies. I will attach a step file and an image which indicates the direction of travel I'm trying to achieve.

So just to expand on this a little, I want to laser cut a disc which will insert into the gaps in the plastic sheet and cover the whole sheet in a single rotation. I'll then assemple a shaft with these discs and spacers to cover both ends of the sheet as well as the middle to pull the whole thing through a mechanism I'm building.

Because the spacing of the adge and the middle gaps is different, I'm not sure that the rack and pinion method is appropriate. But I probably wrong?!

Thanks 🙂
