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.

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

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...

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.

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.

该指令应用于圆柱棒料外圆表面粗车、加工余量大、需要多次粗加工的情形。 F、S、T—粗加工过程中的切削用量及使用刀具。 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； 半精加工完成后，刀具快速退至循环起点，结束粗车循环所有动作。 上述循环指令应用于工件内径轮廓时，G71就自动成为 内径粗车循环，此时径向精车余量Δu应指定为负值。 图中给出了4种切削模式（所有这些切削循环都平行于Z轴）下U和W的符号判断。 …

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).

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.

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).

G71 is a roughing operation. It is going to remove as much material as possible. The common tool or insert is 80°. Compare the angles for 55° and 80° angles.
