Plunge feed rates in circle mill, dynamic paths, etc?

[neurosis]

Are there any plans in the future to change these paths to use the plunge feed rates? When I am plunging a c-bore in titanium, I would like to be able to plunge down at a different feed rate than the helical feed outward.

 

Ive noticed that when you set an entry feed in the plunge area of the dynamic paths it also does not use the plunge feed rates to ramp down in to the material. It uses the full programmed feed rates. Even in aluminum this can be bad news unless you change your ramp angle to something ridiculous.

Off topic but same subject. Anybody know of any technical data related to Plunge speeds and feeds, ramp angles and such. I've been using helix bore, 2d ramp, and The HST opti paths quite a bit recently and and have been guessing at the values. So far so good but I'd like to optimize these parameters and get some real theory on paper.

Most cutters can only handle 1-3 degrees of Ramp, so on a small arc it does not equal much Z depth per helix.

 

as for the off-topic Q, check your tooling catalog, they almost always have maximum ramp angle, etc, Only time they don't is if the tool is not "designed" for ramp, but that's never stopped me you just have to be conservative

 

Helix bore is favourite holmaking path, why put 10 drills in your toolchanger when 1 endmill will do all the same size holes (not always the best time wise on production parts)
