Here is another cnc programming example, this cnc programming example shows the use of G71 Canned Cycle and G70 for Fanuc CNC Control.
G71 Turning Cycle
Although I already have posted about the G71 Turning Canned Cycle(Rough Turning Cycle), but that blog post just illustrates the use of G71 and G71 parameters.
This cnc programming example shows a complete contour cutting with G71 and finish cut on contour with G70.
G70 finishing cycle for fanuc cnc control can also be used with G72 Facing cycle for fanuc control. Usage of G70 Finishing cycle with G72 Facing cycle is same as shows here in the following example.
