Just recently purchased the shapeoko 4 XL and I’m still learning all the tricks of the trade. I have the Amana bowl bit 45982 and I’m looking for all the parameters/settings to add the bit to my tool list. Does anyone have any recommendations?
Never used one myself but there seems to be pointers in this thread
My bowl bit is Whiteside (not Amana), but 3/4" diameter like yours. I’ve only ever used it on endgrain cutting boards (Hard Maple and Walnut), and I used these feeds and speeds, which are conservative and avoid chattering and other bad noises:
Depth of Cut: .02"
I’m sure you can be much more aggressive on softer wood or non-endgrain.
Thanks I will give that a try.
plunge very very slowly… no more than 5ipm… these bits are NOT made for plunging at all.
Even feed rates I tend to be conservative, 20ipm to maybe 40ipm depending on the material
DOC about 0.04" max
RPM: Don’t go to the max of the router, more middle of the road.
(I tend to cut a bit more conservative and aim for a nicer finish… I’m sure you can feed faster than these but… think of a bowl bit mostly as a finishing pass bit, not a roughing bit… and you want cut quality there)
oh also add it as a regular endmill as if the rounded part is not there, with the full diameter of the bit,
and set the stepover such that you overlap on the bottom flat part
