This problem usually occurs when you run these Canned Cycles in a sub-program…
Fanuc Alarm 5: NO DATA AFTER ADDRESS Fanus Control Model: Modern Series: Fanuc 16i, 18i, 21i (Models A & B), Fanuc 0, 3, 6, 10, 11, 12, 15 The Fanuc Alarm is a standard Program/Storage (P/S) alarm found across nearly all modern and legacy Fanuc CNC control series. Description This alarm appears if no numerical value is…
Facing is the process of making the top surface of a workpiece perfectly smooth, straight and level. It is widely used in CNC machines. In this process, the cutting tool usually moves in the X and Y axes and cuts the material in a small depth (Z axis) to eliminate the uneven surface. Facing is…
G75 is an excellent CNC group cycle, one of the best advantages of which is that this command does not require repeated code writing, but rather contains complete logic in a single command. This code is a great way to save time, protect the tool, and achieve better quality. G75 is typically used for radial…
Fanuc Alarm 157: TOO MANY TOOL GROUPS Fanus Control Model: 16i / 18i series, 21 / 21i series Description Each control model has a defined number of tool groups. This alarm is displayed when this number exceeds the machine’s limit. If the programmer does not delete unnecessary tool groups, the control stops the machine’s operation….
FANUC Alarm 71: Data Not Found Fanus Control Model: 30i, 31i, 32i Model A, 16i / 18i Series Description When you use a specific G-code or M-code that is linked to a specific parameter or macro, but it does not exist in the data memory. How to Fix Alarm Check the program coding and see…

The G72 Facing Cycle is an important programming command that is widely used in CNC lathes. This command smooths the surface of the workpiece by removing material to a certain depth. G72 is a very useful facing cycle, especially for circular profiles and medium-hard materials. It completes the facing operation by repeating the programmed tool…
