high feed setup

[Chuckles the Clown]

I want to try a high feed post, but not sure about the setup.

 

If I set the maximum feed it seems to go above that number when I post.

 

Is there any relationship between the original feed rate that was given for a particular tool, and the resultant high feed value?

 

Hope that makes sense.

Some of the other guys might get pissed at that but, damn, I think that's pretty freakin funny!

 

Thanks for the first smile I've had today; unfortunately I'm no help for you.

Chuckles,

 

There is no relationship between the original feed of the cutting tool and the feed values posted when using the high feed option. Also, you might see feed values higher than the maximum feed rates you specified because of the "air cutting feed rate" value. The air cutting feed rate is the feed rate the machine moves at whenever Mastercam detects that no material is being cut, for example: after a pocket is finished roughing and the tool is travelling across the pocket floor ("keep tool down") to take a finish cut around the periphery of an island in the pocket. If you set "air cutting feed" to or near the maximum feed rate your machine is capable of it saves a considerable amount of time, particularily in big mould programs. Also you might experience a situation where using high feed will actually give you a slower cycle time than what you had programed on the original toolpath because of deacceleration in the corners. At first, this wouldn't seem to be an advantage but the benefit comes in things like fewer broken tools, longer tool life and not changing those broken tools every 20 minutes. High feed is a combination of material volume based and machine dynamics so it'll take some playing with different combinations of feed, look ahead and acc/dec to find out what works best for your machine. Try hitting Alt-H and go through the Help stuff provided with Mastercam on Highfeed and you'll be a little wiser. Good luck,

Thanks for the info. Just trying to gather as much as I can.
