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.

Two types of machining paths are addressed with a G71 command. The first type of path (Type 1) is when the X-Axis of the programmed path does not change direction. The second type of path (Type 2) allows the X-Axis to change direction. For both Type 1 and Type 2, the programmed path of the Z-axis cannot change direction.

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. Depth of cut. Retract height. Finishing allowance in x-axis and z-axis. Cycle cutting-feed, spindle speed. G71 U...

Fanuc G71 for Boring Oprtaion - this programming example also illustrate how G71 turning cycle can be used for internal machining (boring operation).

G71粗车外圆加工走刀路线。刀具从循环起点A开始，快速退至C点，退刀量由Δw和Δu/2决定； 快速沿X方向进刀Δd深度，按照G01切削加工，然后按照45°方向快速退刀，X方向退刀量为e，再沿Z方向快速退刀，第一次切削加工结束；

Haas cnc lathe uses one-line syntax of G71 roughing canned cycle. This cnc program example shows the use of G71 turning cycle for ID roughing (Inside roughing). You might like. In the below cnc programming example. 1 – A boring bar is used for the whole the roughing operation with G71 Rough Turning Cycle.

Jan 2, 2024 · There are essentially two ways in which G71 cycles vary from one controller to the next. They can be either 2 line or 1 line syntax. Let's see what each entails. Two Line Versus One Line G71 Syntax. If you have a later model Fanuc control, it probably has 2 line syntax.

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.

Nov 18, 2021 · Motorola Moto G71 5G Android smartphone. Announced Nov 2021. Features 6.4″ display, Snapdragon 695 5G chipset, 5000 mAh battery, 128 GB storage, 8 GB RAM.

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).
