Creating Keyhole toolpath in carbide create

How to create key hole toolpath in carbide create? and what will be settings of keyhole tool such as feed, spindle speed and plunge rate?

See:

Carbide Create V7 Question- Keyhole toolpath

I’ve seen more and more references to people trying to work out how to make keyholes in CC. We’d be open to adding that as a toolpath in V7 so I’d like a little feedback. To simplify, we’d probably define the location with a circle, like the drilling toolpath, and then you’d define how tall you’d like the keyhole to be, and what direction from the center, Y+, Y-, X+, X-. We’d probably implement the toolpath as a plunge, line to the end and back, then a retract. We would not offer to “expand”…

I have a specific Freud bit and will include the custom tool database below. The Freud site had F&S that were fantastically aggressive for their bit. Basically you just draw a circle. The circle can be size but the keyhole tool path will just go straight down to the depth of cut you specify in the tool database. It will then plow forward the length you specify. I typically go 1" to make sure the keyhole entrance is not so close to the end of the keyhole.

The parameters are from the specifications for my Freud 70-104. You will have to get the specifications for the bit you have. The OEM will have the measurements or you can just measure it.

Here is a picture from the Freud site about my bit.

I think it’s a great idea!

Explanation is clear enough and it worked. Thank you so much.
