z Diameter or radius programming: currently, because there is only one bit parameter No
1.2 to select the diameter or the radius programming and is valid to only X axis, Z and Y
axis use the only radius programming in G2, G3, and X axis is selected by the
parameter;
z The tool nose direction of C tool compensation is 0 in G17, G19.

Command function: 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). This method is useful in cutting a front
surface and grinding a cam shaft on the machine.
Command explanation: G12.1, G13.1 are non-modal
Linear axis: X or Z, Y or 4
th
or 5
th
axis
Rotary axis: axes except for feed axis(Y or 4
th
or 5
th
axis)
Before starting the polar coordinate, set the linear axis and the rotary axis by No.235
and No.236.
Taking example of the linear axis X and the rotary axis 5

Polar coordinate interpolation plane: G12.1 starts the polar coordinate interpolation mode and
selects a polar coordinate interpolation plane(below), and the polar coordinates are completed in
the plane.
