FANUC CNC Milling Programming Basics - G01 Linear Interpolation 2

 Here is an illustrative diagram of a contour machining trajectory. Assuming the coordinate system origin is set at the lower-left corner of the workpiece surface, programming is done based on the tool center. A 2mm cut into the workpiece is made using the G01 linear interpolation command to create the milling path for this contour. In the program, it is important to first position the tool at X0Y0Z100 to verify the correctness of the tool position. Typically, the Z-axis is moved to a safe height of 100, followed by the movement of the X and Y axes to reach the initial confirmation point. Alternatively, coordinate system verification can be performed before executing the program, allowing direct movement to the plunge point at X40Y40.

Please refer to the example program below:

Numerical Control Programming Instruction Study - G01 Linear Interpolation 1

  When learning numerical control programming, G01 is one of the first interpolation instructions to be learned. Its purpose is to move the tool along a straight line at a given speed to reach the target point. The format is as follows: G01 X_Y_Z_F_ Here, X_Y_Z_ represents the position of the target point. When executing this code, the tool will move along a straight line at the set speed F to reach the target point X_Y_Z_, creating a linear motion. Importantly, this instruction implies that the tool must move in a straight line from its current position to the target point. Therefore, if we want to move along a specific line on the workpiece, we need to first move the tool to the starting point of that line. Let's take the example of a key-shaped contour composed of straight line segments to illustrate the application of the G01 instruction. Assuming the tool is cutting down 2mm into the workpiece for the trajectory. The contour consists of an outer and inner ring. When the outer ...

FANUC CNC Milling Programming Basics - G02/G03 Circular Interpolation 3

  In this example, we have a toolpath composed of a combination of straight lines and arcs. We will use a mix of G01, G02, and G03 commands for programming. It's important to pay attention to the changes in toolpath elements and adjust the modal commands accordingly. When using circular interpolation commands, be mindful of the clockwise or counterclockwise direction and specify the correct arc radius. Additionally, we typically program machining operations in the G17 plane by default, but there are also G18 and G19 planes for arc machining. When using tool radius compensation, it is necessary to select the cutting plane, although the default G17 plane does not require explicit specification. Examples of arc machining in other planes will be provided later.
