Tips for making acog that interacts with a linear pattern.

[mdwelchALZ5M]

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 🙂
