The axes of polar coordinate interpolation (linear axis and rotary axis) should be specified in advance, with corresponding parameters. G112 and G113 can be used in place of G12.1 and G13.1, respectively. Specify G12.1 and G13.1 in Separate Blocks. G13.1 Polar coordinate interpolation mode is cancelled (for not performing polar coordinate interpolation). Specify linear or circular interpolation using coordinates in a Cartesian coordinate system consisting of a linear axis and rotary axis (hypothetical axis). G12.1 Starts polar coordinate interpolation mode (enables polar coordinate This function is useful in cutting a front surface and grinding a cam shaft for turning. Polar coordinate interpolation is a function that exercises contour control in converting a command programmed in a Cartesian coordinate system to the movement of a linear axis (movement of a tool) and the movement of a rotary axis (rotation of a workpiece). In this article, we describe how to use polar coordinate function on CNC Lathe machines which is called G12.1 and G13.1 G code. ![]()
