2d contour depth cuts

[jesse@desemco]

Is there a way to make my depth cuts start at the bottom and work up?

I am reaching thru a hole with a key cutter to make a counterbore from the other side.

I need to make 5 cuts in each counter bore, 24 holes

 

I can make surface finish contour do (almost) what I want. -I would like cutter comp. and I would like to transition at the exact center of the hole

 

thanks

invert the top of stock and the final dept

Contour toolpath, use the ramp option, with a plunge ramp motion. After creating the toolpath right click on it, choose edit selected operations and reverse the cut, one thing missing with this is it won't start every pass in the center, only first pass and at the end of the cut.

Does not seem to work.

I set my top of stock as the bottom of the counterbore

I set the final depth as the top of the counter bore

It still cuts from the top to the bottom.

I had to add finish passes to make it take depth cuts at all.

set the depth to finish depth wanted (-.500)

set top of stock to starting depth (-1.0)

use ramp option

works for me

create a contour with depth cuts off starting at the lowest (1st cut you wanna take)

mill toolpaths - transform

type - translate

on the translate tab under method pick between points

set your instances to the # of cuts you wanna take

from point leave at 0 0 0

to point = what ever you want for your depth cuts <<< put that in the z value

 

edit

just played with some settings in the source ops (and created a couple dummy ops) here is the code

and I would like to transition at the exact center of the hole

^just adjust the lead in/out^

for ramp up a hole , i simply use threadmill toolpath , it works like a charm, you just got to play with the settings

[jesse@desemco]

I can not ramp the hole, I have to use depth cuts. I'm using a small slot mill.

I am going to use incremental depths and draw my geo where I want it.

I made a path for 1 hole and transform rotate for the rest.

Thanks
