Cutting point command (Type 2) ON

Q: What does Mazak G-code G43.9 do?

G43.9 — Cutting point command (Type 2) ON on the MAZATROL SmoothX control (INTEGREX e-670H). Cutting point command function provides a special type of tool-tip point control in order that the cutting point (point of contact between tool and workpiece for chip removal) may precisely describe a tool path as programmed on the machining surface. Therefore, the tool path itself, once described in a machining program, need not be modified according as the geometry (tool diameter, corner radius, etc.) of the tool to be used is changed, which is not the case with the ordinary tool-tip point control.  This function is valid only for five-axis control machines.  If the required option is not added, giving a command for selecting the mode of cutting point Tool rotating type Table rotating type Mixed type

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.

G43.9 is modal (group 08) — it stays in effect until another code of the same group replaces it.
