Re: [Emc-users] G71 lathe roughing cycle

[Greg B. <sku...@ya...>]

I have not had the chance to run a dual turret lathe with a FANUC 
control, but I have a few thousand hours on a OKUMA dual turret.

Currently LCNC treats each axis as a reserved word and you can't duplicate axis.

Okuma's Method to work around this used G13 & G14 to define what the 
program code would apply to. G13 was for the upper turret, G14 for the lower. By adding P000xx codes ( "Priority code" ) 
you were able to define which moves were independant and which could be 
executed simaltainiously. (adding this might require a GUI mod of a 
split screen for the different turret programs, even though its all one 
top down program in the file.)


So far LCNC has been able to move forward as a "one size fits all" program package, where the only major divergant config is the type of KINS file the user chooses.

The ability to map/remap codes sounds like an important way to allow 
different machine type to move to more machine specific gcode 
structures. At the initial config a install script could be called to 
sell the interpreter for "lathe", or "mill" etc.

While the ability to define a multi turret or multi mill head type machine is likely a LCNC v2.8 or later type project, I would like the option of 
having G12/G13 pocketing in milling and G13/G14 for lather turret 
designation at some future time. Code mapping may be the first step in that 
direction.
