Lathe dwell

[Paul Felger]

Hey guys,

Is there a way to dwell in a particular chosen corner in the finish toolpath?

Thanks

[Paul Felger]

Or slow down on aproach of a corner then pick the feed rate back up, like you can on mill?

 

Thanks

Paul,

 

I think t he toolpath editor is going to be your friend in this case

[Paul Felger]

I was afraid of that, I hope X3 has some better lathe stuff! Mill has it all Or am I just being lazy?

On our Hitachi lathe a dwell is accomplished with a G4 command. It needs to be inserted right after the line for movement. Time is controlled with a P value.

 

Example

 

G1 Z-1.0

G4 P1.0

X 1.5

 

Here the machine will feed to Z-1.0, dwell for one second and then feed to X 1.5

yeah, I do that all the time, edit here edit there.. It would just be nice if MCX2 Lathe had that option, and even ask how many revs. you want so you dont have to figure it out (not that its that hard to do), Im just surprised that a groove tool path has it, but no finish tool path. I use some very small rad. tools (.0015R) on finish and if I dont dwell it will blow right by, and snapping it off.

Have you tried change at point?

This is what I normally use.

 

In operations manager, left click on Geometry

then in Chain Manager, right click on Chain you want to add dwell to and pick "Change at Point".

Dwell is just one of the options you have.

Calvin,

Just tried it out. Pretty handy function.

 

Thanks,

What do you do when "Change at Point " is greyed out ?

[Ron Branch @ Verisurf]

Move to the next point the one you are on is a rapid move and it will not allow change at point on rapid moves only feed moves.
