G92 threading cycle is used for threading on a cnc lathe machine. The added benefit of G92 thread cycle is that G92 G-code gives cnc machinist full control over the…
G92 is used for simple threading, however, multiple passes for threading are possible by specifying the X locations of additional passes. Straight threads are made by specifying X , Z , and F . By adding an I value, a pipe or taper thread is cut.
15 cze 2011 · The only options you have are "Cycle" which outputs a G92, and longhand, which posts out each and every pass (infeed, cut, exit, retract) with G32. However, it does still allow you to select an infeed angle with the G92 cycle, other than just 0 degrees (straight radial plunge infeed). For example, when I select a 30 degree infeed, I get this code:
13 gru 2022 · G92 Threading works exactly the same as G76 except you need to programme every pass. This would be a pain in the arse but hear me out. The Haas G76 cycle does not have any facility for a spring pass. This is where you add extra cuts at the end of a threading cycle to take out any metal left from the tool pushing off.
If the lathe control uses G92 for simple threading cycle, use G50 for the position register command. This applies for older controls only, since modern controls use advanced geometry offsets. The schematic illustration of a G92 thread cutting cycle is shown in Figure 38-8.
BASIC THREADING CYCLE - G92. Computerized control systems can perform many internal calculations and store their results in control memory for further use. This feature is especially useful for thread cutting, since multiple repetitions of block-by-block tool motions can be avoided and the program shortened quite significantly.
6 wrz 2011 · G92 Threading cycle. We normaly cut tapered thread with this G92 cycle. On our new puma 400LM with Fanuc 32i he cuts straight. has it to do with a parametersetting?
