The G71 roughing cycle is used to rapidly remove excess material from the stock billet. In this article I explain how we program using G71.

Dec 16, 2024 · G71 is a powerful CNC lathe cycle for efficient material removal, defining key parameters like depth of cut, retract value, and finishing allowances. The cycle requires a subroutine to define the part’s profile and can be used in either a two-line or single-line format.

G71 turning cycle is used for rough-material removal from a cnc lathe component. G71 turning cycle makes large diameter cutting easy. Cutting can be done in simple straight line or a complex contour can also be machined very easily.

Sep 6, 2019 · The G71 roughing cycle is used for rough-material removal from a CNC lathe component. It enables CNC machinists to remove material quickly on a CNC Lathe while also writing the cutter path as a subroutine that can be reused during the finishing cycle (G70).

Fanuc programming example which shows the use of multiple fanuc canned cycle in cnc programming, Following canned cycle are used in this cnc lathe programming example. This programming example also illustrate how G71 turning cycle can be used for internal machining (boring operation).

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.

Jan 2, 2024 · Master the G71 Rough Turning Cycle with our detailed guide, including programming tips, syntax differences, and practical examples for efficient CNC machining.

G71 roughing cycle on the lathe can be called “auto turning cycle”. It is not a repeating cycle in the way that peck drilling is. G71 needs some parameters so it does not cut into the true profile of the part.

Mar 18, 2024 · Master G71 Type 2 rough turning with pockets using our detailed guide. Learn the differences, invoke cycles, and improve your CNC machining skills.

Apr 3, 2024 · Fanuc’s G71, G72, and G70 canned cycles are invaluable for lathe operations, particularly for internal machining such as boring and facing. These cycles automate the roughing and finishing processes, enhancing efficiency and precision. G71 is …
