4.8.3.5 G2: Clockwise Circular/ Helical Interpolation

 Function:

Circular interpolation: The cutter conducts the cutting of the processed object in the clockwise direction

at the feed speed given by parameter F on the circular arc with the fixed radius or the fixed center of a

circle of the specified plane.

Helical interpolation: The cutter moves in the clockwise direction on the circular arc of the specified

plane，which is circular interpolation and simultaneously moves in the vertical direction of the specified

plane at the feed speed given by parameter F, which is linear interpolation.

 Format:

Format 1: N_G2 X_Y_Z_A_B_C_P_Q_I_J_(I_K_/J_K_)T_ E_E_F_

Format 2: N_G2 X_Y_Z_A_B_C_P_Q_R_T_ E_E_F_

 Parameter explanation:

N_: The row number of G code in NC program

X_Y_Z_: Specify the terminal positions of axis X, Y and Z corresponding to the terminal point of circular

arc; Unit: unit, data type: REAL.

A_B_C_P_Q_: Specify the terminal position of each added axis, Unit: unit, data type: REAL.

I_J_: Specify the coordinate position of the center of a circle of XY plane, Unit: unit, data type: REAL.

I_K_: Specify the coordinate position of the center of a circle of XZ plane, Unit: unit, data type: REAL.

J_K_: Specify the coordinate position of the center of a circle of YZ plane, Unit: unit, data type: REAL.

T_: Specify the quantity of one full circle, Unit: circle, data type: UINT.

E_: Specify the acceleration and deceleration of the cutter. The positive number refers to the

acceleration; the negative number refers to the deceleration, Unit: unit/second

, data type: REAL.

F: Specify the feed speed of the cutter, Unit: unit/second, data type: REAL.

 Instruction explanation:

 Two axes among axis X, Y and Z make the circular interpolation on the plane specified by

instruction G17/G18/G19. The 3rd axis specifies the plane to make the linear interpolation

vertically.

 The added axis A, B, C, P and Q make the linear interpolation. The linear interpolation and circular

interpolation and start up or stop simultaneously.
