add dwell to lathe roughing cycle

[Sbarner]

Hi All,

 

After the 4" diameter piece of aluminum I'm machining has been drilled with a 2.125" diameter spade drill, I have to do some turning of the ID. The piece is 8" long, and while I'm having success with turning the ID, I'm having problems as well. I'm feeding at .025" per rev, and having problems evacuating the chips from the bore. Consequently, when the boring bar gets to within about .5" of the bottom, I watch the Z axis load monitor and the spindle load monitor start getting EXTREMELY high.

 

So then, I was thinking that I wanted to add a one to two second dwell at the beginning of the pass. THis would allow the coolant to have a couple dedicated seconds to wash the chips out. But, short of hand-coding each G04, I'm stumped for a way to output the dwell. Any thoughts?

 

Oh...I'm using X3, with MPLMASTER on a Haas SL-20 lathe.

 

Thanks all.

Yeah break the chain into pieces. Now use the toolpath editor to then make a feed change or use cantext to insert G4 into at that point. What I would od it make a feed rate change using the toolpath editor for the last .5 to allow the chip clearance to catch up. Should only have to do it for a couple passes.

The toolpath is a standard lathe rough.
