Having a go with F360....

[Davek0974]

Ok, first job :)

Something i used to make manually in small batches, would use a 5C collet block horizontally in vise, cut one side, rotate 90deg cut next and so-on. The diameter of the tool created a radius at the root of the square part.



Gonna have a go with CAM, modified the vise jaws so i can clamp a blank vertically and work round tip using a ball-nosed cutter.

Blanks are 1/2"dia and tip is 5.5mm sq. It also 605m36 steel so slightly harder than plain mild.

I have it drawn up in F360 and worked out the feeds/speeds in HSMAdvisor which gave me 420rpm, 84mm/min on a 12mm HSS tool. DOC is 11mm - 6mm radius and 5mm straight.

F360 wants to take the whole cut in one pass - would you feel happy with that, seems heavy. Although i selected 2d Adaptive, i think its too simple to work any magic on and it seems to have created a standard path.
