HIGH SPEED MACHINING V9

[FISHING MAN]

Hi All,

 

I have read many topics on high speed machining,But I still not sure if I should be using it or not.I have a aluminum block that has to have a rectangular pocket machined 3.5 deep .What advantage would I have verse using zig zag toolpath?I saw a video on SurfC#@#@ using something simular.I am just not sure on how to set it up and if I should be using it.HELP

 

Thank you ,

HIgh speed pocket I find is only good if your machine is actually a high speed machine. The idea is to take lots of small cuts really fast instead of hogging it out. Our machines are good, but not high speed so we don't use it (it is slowwer for us).

 

The HSM surface toolpaths are great, however, with or without a highspeed machine.

John,

 

I would highly recommend using the High Speed pocket method, just turn off the Trochodial motion and use only the corner rounding radius option.

When roughing, our considerations typically have to do with the layout of the part.

 

If the design of the part allows you to make long uninterrupted linear cuts, using the Zig-Zag eliminates a large portion of time where the machine would otherwise be in Acc/Dec.

 

If the design is more closed, I would agree with Colin. High speed pocket with no Trochoidal, only corner rounding. Also a function to reduce Acc/Dec, as well as preserve tool life.

 

It would be nice if the corner rounding feature were available on all pocketing toolpaths.

Thank You,

By turning of Trochoidal the cutter is taking a full cut (slot).If I could e-mail my geometry and toolpath to some one to look at it would really help.
