Fanuc Alarm 37: CAN NOT CHANGE PLANE IN CRC Fanus Control Model: Fanuc 0i, 16i, 18i, 21i, 31i Series Description The Fanuc Alarm 37 occurs when the control encounters a command to switch the active work plane (G17, G18, or G19) while Cutter Radius Compensation (CRC), also known as G41 or G42, is active. How…
Two very important commands are used to eliminate sharp corners of a workpiece or give them a specific shape: Chamfer and Radius. Through these commands, you can round the corners according to the design or create a bevel. The advantage of this is that the workpiece will be safer to handle, its strength will increase,…
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…
Before you start writing a CNC program, it’s essential to understand your machine. First, identify the type of CNC machine you are using, such as a milling machine, lathe, or router. Next, take note of the axes it operates on—most machines have three axes (X, Y, Z), though some may have more. Finally, know the…
What is G00? G00 is a rapid positioning command used in CNC programming. It tells the CNC machine to move the tool quickly from one position to another without performing any cutting operation. The main purpose of G00 is to save time by allowing the tool to travel at the machine’s maximum speed when it…
In CNC programming, the M03 (or M3) command is used to start the spindle in a clockwise direction. For the command to work correctly, it must be paired with an S word, which defines the spindle speed in Revolutions Per Minute (RPM). The standard format for starting the spindle is: G97 S[speed] M03 Simple G-code…
In the world of precision manufacturing, CNC (Computer Numerical Control) machines are the workhorses that turn raw materials into intricate components. While both CNC milling and CNC turning are subtractive manufacturing processes—meaning they remove material to create a final shape—they operate on fundamentally different mechanical principles. The primary difference lies in which part moves: In CNC milling,…
In CNC programming (specifically for lathes/turning centers), T0101 is a command used to select a specific tool and its associated offset. It is most commonly found in Fanuc, Haas, and similar control systems. The code is typically split into two parts: Why are there four digits? While it is common to see the numbers match (like T0101, T0202, or T0505),…
CNC (Computer Numerical Control) lathe programming might seem like learning a foreign language at first, but it follows a very logical structure. Most industrial lathes use Fanuc-style controls, which rely on G-codes (preparatory functions) and M-codes (miscellaneous functions) to tell the machine exactly how to move, spin, and cut. Think of a CNC program as a recipe: you define the…
CNC stands for Computer Numerical Control. It refers to the automated control of machine tools using a computer, where pre-programmed software and code dictate the precise movement and operation of cutting tools, drills, lathes, and other machinery. Unlike traditional manual machining — where operators physically guide tools using handwheels and levers — CNC machining relies…
