cams and spirals

[Steve Truscott]

Hi Art,
I see Vexx has a golden spiral generator . I need an Archimede s Spiral for a cam in a project. Is that on the horizon?
While I am here I was looking at cam design in general with constant speed, constant accelerat ion et al. So far I have not found any informati on on generatin g them on the net. Could they be a subspecie s of spirals?

Hi Steve:

   I didn't add for that in the spirals, but will look at adding a selection for it
in that dialog.

I realise this thread is over a year old now, but I have a similar requireme nt for a nice, smooth-moving cam for an electro-mechanical clock design I'm working on. The option to easily design a cam including a smooth increase/decrease of accelerat ion which I can then copy out to my CNC router for cutting would be brilliant . Quite how many derivativ es of position (velocity, accelerar ion, jerk, snap, crackle, pop) Art decides are enough to fire his imaginati on are not for me to decide

Kit:

    Ill give it some research. I've just had a large crash here and am still in the end
stages of rebuildin g. Im almost there and have nothing committed to other than research
for a couple of months to determine what I feel like doing next. Cams and Worms are under
considera tion.
