Tornado cycle

Q: What does Mazak G-code G130 do?

G130 — Tornado cycle on the MAZATROL SmoothX control (INTEGREX e-670H). Tornado tapping cycle is provided to machine a tapped hole by one axial cutting motion with the aid of a special tool. While usual tapping cycles require multiple tools to be used in sequence, use of this cycle function spares tool change time as well as repetitive cutting motion in order to enhance the machining efficiency. This cycle function is only available on machines equipped with the Y-axis control facility. Note: Tornado tapping function requires the following parameter settings for macro-call G-codes: J37 = 100009401 (Fixed value for the number of the macroprogram to be called for tornado tapping) J38 = 130 (Fixed value for the number of the G-code to be used for macro call) J39 = 2 (Fixed value for the type of macro call)

Q: What is the programming format of G130?

The following format refers to hole machining on the face [or O. D. surface]. G17 [or G19]; G130 R_Z_D_T_V_F_H_I_J_K_Q_E_M1 [or M0]; X [or Z] _Y_; (Setting of hole position) G67; Hole machining axis R E Cutting surface

Machine-specific. This G-code reference is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (EIA/ISO programming manual H747PB0030E). G-code availability depends on fitted options, and groups and behaviour differ between Mazak models and control generations — verify against the manual for your own machine before programming with any code.
